The Guyana–Venezuela territorial dispute is an ongoing territorial dispute between Guyana and Venezuela over the Essequibo region, also known as Esequibo or Guayana Esequiba in Spanish, *
 * a 159500 km2 area west of the Essequibo River. The territory, excluding the Venezuelan-controlled Ankoko Island, is controlled by Guyana as part of six of its regions, based on the 1899 Paris Arbitral Award, but is also claimed by Venezuela as the Guayana Esequiba State.  The boundary dispute was inherited from the colonial powers (Spain in the case of Venezuela, and the Netherlands and the United Kingdom in the case of Guyana) and has persisted following the independence of Venezuela and Guyana.

In 1835, the British government commissioned German-born explorer and naturalist Robert Hermann Schomburgk to survey British Guiana's boundaries. This survey resulted in what came to be known as the "Schomburgk Line", which extended beyond the area of British occupation and gave British Guiana control of the mouth of the Orinoco River. These borders were disputed by Venezuela, and tensions worsened after the discovery of gold mines in the region in 1876, culminating with President Antonio Guzmán Blanco severing diplomatic relations with the United Kingdom in 1887. As a result, Venezuela elected the United States as their representative, leaving no Venezuelan citizen to represent their country's interests. The United Kingdom and Venezuela went into arbitration with mediation from the United States, which resulted in the Paris Arbitral Award in 1899 and ruled largely in favor of Britain. In 1949, a memorandum written by Severo Mallet-Prevost, official secretary of the US–Venezuela delegation in the arbitration, and published posthumously, stated that the Arbitral Award resulted from the pressure by the Tribunal President Friedrich Martens and a political deal between Russia and Britain. Said memorandum led to complaints by Venezuela in the United Nations in 1962, which resulted in the Geneva Agreement, signed with the United Kingdom in 1966.

The status of the territory is subject to the Geneva Agreement, which was signed by the United Kingdom, Venezuela, and British Guiana on 17 February 1966. This treaty stipulates that the parties will agree to find a "practical, peaceful, and satisfactory solution" to the dispute. Should there be a stalemate, according to the treaty, the decision as to the means of settlement is to be referred to an "appropriate international organ" or, failing agreement on this point, to the Secretary-General of the United Nations. The Secretary-General referred the entire matter to the International Court of Justice (ICJ). On 18 December 2020, the ICJ accepted the case submitted by Guyana to settle the dispute. In December 2023, Venezuela held a referendum asking the Venezuelan electorate whether the region should become a state of Venezuela and its population become citizens, where it declared that the results showed overwhelming support for such action. No vote was held in the disputed region. Currently, Venezuela claims all of the land west of the Essequibo River, which it refers to as Zona en Reclamación or Zone in Reclamation. Historically, this did not include the tributaries of the Amazon River and the Pirara area which were only ceded to British Guiana in 1904 during arbitration with Brazil. The Northwestern border of the Essequibo follows the 1905 border as established by the British-Venezuelan Mixed Boundary Commission, in accordance with the Arbitral Award of 3 October 1899. Venezuela currently seeks to abrogate the legal borders and currently agrees only to the Essequibo River boundary.

Demographics
In 2023, the population of Essequibo was estimated to be around 125 thousand inhabitants, or 15.8% of the total population of Guyana.

Colonial history
Before the arrival of European colonizers, the Guianas were populated by scattered bands of native people. The Warao people are considered to be the first inhabitants of Guyana, followed by the Arawak and Kalina people. The native tribes of the Northern Amazon are most closely related to the natives of the Caribbean; most evidence suggests that the Arawaks immigrated from the Orinoco and Essequibo River Basins in Venezuela and Guiana into the northern islands, and were then supplanted by more warlike tribes of Carib Indians, who departed from these same river valleys a few centuries later. Before other European powers had made excursions into these lands, Spain had already declared ownership of this region, as per the Treaty of Tordesillas. The treaty was not signed nor recognized by other colonialists, such as the Dutch or the English, who inserted themselves into the Guianas between areas claimed by the Spanish Empire and the Portuguese Empire.

15th Century
The first European encounter with the region occurred when the ships of Juan de Esquivel, deputy of Don Diego Columbus, son of Christopher Columbus, arrived in 1498. The region was subsequently named after Esquivel. In 1499, Amerigo Vespucci and Alonso de Ojeda explored the mouths of the Orinoco and were reportedly the first Europeans to venture into the Essequibo region. By 1581, Dutch colonists from Zeeland established a trading post on the banks of the Pomeroon River, marking the beginning of Dutch colonization in the area. This Pomeroon colony eventually merged with the Essequibo colony, becoming a significant trading destination for the Dutch colonial empire until control was transferred to the British Empire.

16th Century
Dutch colonization of the Guianas primarily occurred between the mouths of the Orinoco River in the west and the Amazon River in the east. Although the Dutch presence in the Guianas was noted by the late 1500s, many early documents regarding Dutch discoveries in the region were lost. By the 1570s, reports emerged of Dutch involvement in trade in the Guianas, although scant evidence exists. At this time, neither the Portuguese nor the Spanish had established any settlements in the area. In 1596, a Dutch fort was constructed at the mouth of the Essequibo River on an island, but it was destroyed by the Spanish later that year.

Dutch interest in exploring the Guianas increased following the publication of The Discovery of Guiana by Sir Walter Raleigh in 1597. A Dutch expedition launched on 3 December 1597 from Brielle, traversing the coasts between the Amazon and Orinoco. The expedition, documented by A. Cabeljau, provided more realistic information about the region compared to Raleigh's account, revealing Dutch travels along the Orinoco and Caroní rivers and the discovery of numerous previously unknown lands. Cabeljau reported positive interactions with native populations and friendly encounters with the Spanish in San Tomé. By 1598, Dutch ships were frequenting Guiana in efforts to establish settlements.

17th Century
Another Dutch fort, supported by indigenous groups, was established at the mouth of the Essequibo River in 1613, only to be destroyed by the Spanish in November of the same year. In 1616, Dutch ship captain Aert Adriaenszoon Groenewegen founded Fort Kyk-Over-Al, situated 20 miles downstream on the Essequibo River. Groenewegen, who married the daughter of an indigenous chief, controlled the Dutch colony for nearly fifty years until his death in 1664.

To protect the Araya salt flats, known as the "white gold" of the time, from incursions by English, French, and Dutch forces, the Spanish Crown ordered the construction of a military fortress. Completed in the early part of 1625, the fortress was named Real Fuerza de Santiago de Arroyo de Araya, with Santiago representing the patron saint of Spain, Arroyo named after Governor Diego de Arroyo Daza, and Araya denoting the location. It was the first significant fortress of the Captaincy of Venezuela. Over the years, concerns arose within the Spanish Crown about the high costs associated with maintaining the fortress, particularly after sustaining damage from an earthquake in 1684 and subsequent flooding from a hurricane in 1725.

By 1637, Spanish reports indicated Dutch presence in settlements along the Amacuro, Essequibo, and Berbis rivers, with alliances formed with indigenous Aruac and Carib populations. Dutch forts were reported from Cape North at the Amazon River to the mouth of the Orinoco River by 1639. Captain Groenewegen was credited with keeping both Spanish and Portuguese settlements at bay.

During a speech to the Parliament of England on 21 January 1644, English settlers who had explored the Guianas asserted that the Dutch, English, and Spanish had long sought to discover El Dorado in the region. The Dutch were noted for their expertise in navigating the Orinoco River over many years, leading to subsequent encounters with the Spanish, who later restricted Dutch access to the river.

In 1648, Spain signed the Peace of Münster with the Dutch Republic, recognizing the Republic's independence and conceding small Dutch possessions east of the Essequibo River. However, in the decades following the treaty, the Dutch gradually expanded west of the Essequibo River into the Spanish Guayana Province. These new settlements faced regular challenges and destruction by Spanish authorities.

Significant Dutch colonization west of the Essequibo began in the early 1650s, coinciding with the establishment of the Pomeroon colony between the Moruka and Pomeroon rivers. Many of these settlers were Dutch-Brazilian Jews who had migrated from Pernambuco. By 1673, Dutch settlements extended as far as the Barima River.

18th Century


In 1732, the Swedes attempted to settle between the Low Orinoco and the Barima River. However, by 1737, Major Sergeant Carlos Francisco de Sucre y Pardo (the grandfather of Antonio de Sucre) expelled them from the forts at Barima, thwarting the Swedish colonization attempt for the time being. By 1745, the Dutch held several territories in the region, including Essequibo, Demerara, Berbice, and Surinam. Dutch settlements were also established on the Cuyuni River, Caroní River and Moruka River. Domingos, Bandeira Jerónimo, and Roque described Essequibo and Demerara as "sophisticated and promising slave colonies".

When Spain established the Captaincy General of Venezuela in 1777 under Charles III, the Essequibo River was reaffirmed as the natural border between Spanish territory and the Dutch colony of Essequibo. In a report dated 10 July 1788, Spanish authorities officially claimed against Dutch expansion into their territory, proposing a border: "It has been stated that the south bank of the Orinoco from the point of Barima, 20 leagues more or less inland, up to the creek of Curucima, is low-lying and swampy land and, consequently, reckoning all this tract as useless, very few patches of fertile land being found therein, and hardly any savannahs and pastures, it is disregarded; so taking as chief base the said creek of Curucima, or the point of the chain and ridge in the great arm of the Imataka, an imaginary line will be drawn running to the south-south-east following the slopes of the ridge of the same name which is crossed by the rivers Aguire, Arature and Amacuro, and others, in the distance of 20 leagues, direct to the Cuyuni; from there it will run on to the Masaruni and Essequibo, parallel to the sources of the Berbis and Surinama; this is the directing line of the course which the new Settlements and foundations proposed must follow." Dutch slaves in Essequibo and Demerara recognized the Orinoco River as the boundary between Spanish and Dutch Guiana, often attempting to cross the Orinoco to live with increased, though limited, liberties in Spanish Guiana.

19th Century
Under the terms of the Anglo-Dutch Treaty of 1814, the Dutch colonies of Demerara, Berbice, and Essequibo were ceded to the United Kingdom. The Dutch had steadfastly defended the territory from British, French, and Spanish encroachments for nearly two centuries, often forming alliances with indigenous peoples in the region who provided intelligence on Spanish incursions and escaped slaves. According to scholar Allan Brewer Carías, the Anglo-Dutch Treaty of 1814 did not establish a western border for what would later become known as British Guiana. Thus, explorer Robert Schomburgk was later tasked with delineating a border. Following the establishment of Gran Colombia in 1819, territorial disputes arose between Gran Colombia (later Venezuela) and the British. In 1822, José Rafael Revenga, Minister Plenipotentiary of Gran Colombia to Britain, conveyed to the British government, on behalf of Simón Bolívar, concerns about British settlers encroaching upon Venezuelan territory: "The colonists of Demerara and Berbice have usurped a large portion of land, which according to recent treaties between Spain and Holland, belongs to our country at the west of the Essequibo River. It is absolutely essential that these settlers be brought under the jurisdiction of our laws or be removed to their former possessions."

In 1824, Venezuela appointed José Manuel Hurtado as its new Ambassador to Britain. He officially presented Venezuela's claim to the border at the Essequibo River to the British government, which did not raise objections. However, the British government persisted in promoting colonization west of the Essequibo River in the ensuing years. In 1831, Britain merged the former Dutch territories of Berbice, Demerara, and Essequibo into a single colony, British Guiana.

Schomburgk Line
Under the auspices of the Royal Geographical Society, the German-born explorer and naturalist, Robert Hermann Schomburgk, undertook botanical and geographical exploration of British Guiana in 1835. This culminated in a sketch of the territory with a line demarcating what he believed to be the Dutch's western boundary. Subsequently, in 1840, he was commissioned by the British government to survey the boundaries of Guiana. This survey resulted in what became known as the "Schomburgk Line". The line extended well beyond the area of British occupation, giving British Guiana control of the mouth of the Orinoco River. However, Schomburgk asserted that it did not encompass all the territory that Britain could legitimately claim.

Venezuela contested Schomburgk's placement of border markers at the Orinoco River and, in 1844, laid claim to all of Guiana west of the Essequibo River. In the same year, a British proposal to Venezuela to adjust the border, granting Venezuela full control of the mouth of the Orinoco River and adjacent territory, went unheeded. In 1850, Britain and Venezuela reached an agreement not to colonize the disputed territory, though the precise boundaries were left undefined.

Schomburgk's initial sketch, published in 1840, remained the sole version of the "Schomburgk Line" until 1886, leading to later allegations by US President Grover Cleveland that the line had been extended "in some mysterious way

".

Gold Discoveries


The dispute remained dormant for many years until the discovery of gold in the region sparked tensions between the United Kingdom and Venezuela. In 1876, gold mines predominantly populated by English speakers were established in the Cuyuni basin, which lay within Venezuelan territory beyond the Schomburgk Line but within the area Schomburgk believed Britain could claim. That same year, Venezuela reaffirmed its claim up to the Essequibo River. In response, the British countered with a claim encompassing the entire Cuyuni basin, though this was merely a theoretical assertion that Britain had no intention of pursuing.

On 21 February 1881, Venezuela proposed a frontier line commencing one mile north of the Moruka River, extending westward to the 60th meridian, and then south along that meridian. This proposal would have awarded Venezuela the Barima District.

In October 1886, Britain declared the Schomburgk Line as the provisional boundary of British Guiana, prompting Venezuela to sever diplomatic ties in February 1887. In 1894, Venezuela appealed to the United States for intervention, citing the Monroe Doctrine as justification. While the United States was reluctant to intervene directly, it did suggest the possibility of arbitration.

Venezuela Crisis of 1895
The longstanding dispute escalated into a diplomatic crisis in 1895 when Venezuela hired William Lindsay Scruggs as its lobbyist in Washington, D.C.. Scruggs argued Venezuela's case, asserting that British actions violated the Monroe Doctrine. He successfully persuaded the US government to accept this claim and intervene. President Grover Cleveland interpreted the Doctrine broadly, asserting American interests throughout the hemisphere beyond just prohibiting new European colonies. British Prime Minister Lord Salisbury and British ambassador to the US Lord Pauncefote underestimated the importance the American government placed on the dispute. The central issue of the crisis was Britain's refusal to include the territory east of the Schomburgk Line in the proposed international arbitration. Ultimately, Britain acquiesced and tacitly acknowledged the US right to intervene under the Monroe Doctrine. US intervention compelled Britain to agree to arbitration of the entire disputed territory.

Treaty of Washington and Arbitration


The Treaty of Arbitration between the UK and Venezuela was signed in Washington on 2 February 1897. This treaty delineated the legal framework for arbitration, with its first article stating that "An Arbitral Tribunal shall be immediately appointed to determine the boundary-line between the Colony of British Guiana and the United States of Venezuela."

The Treaty laid out the procedural and legal conditions for the Tribunal to address and establish a border. Its third article mandated that "The Tribunal shall investigate and ascertain the extent of the territories belonging to, or that might lawfully be claimed by the United Netherlands or by the Kingdom of Spain respectively at the time of the acquisition by Great Britain of the Colony of British Guiana, and shall determine the boundary line between the Colony of British Guiana and the United States of Venezuela.". The Treaty also outlined the rules and principles guiding the Tribunal in demarcating the border.

Venezuela contended that Spain, from whom they acquired the territory, controlled land from the Orinoco River to the Amazon River in present-day Brazil. According to Venezuela, Spain only transferred its claimed Guiana territory to the Dutch, which did not encompass much land within the disputed area. Conversely, Britain, having acquired the Dutch territory, argued that the contested Guiana region was not under Spanish control due to its remoteness and lack of oversight, asserting that the indigenous peoples inhabiting the land had shared it with the Dutch rather than the Spanish, thus falling under Dutch and British influence.

The competing claims were presented to a tribunal consisting of five arbitrators: two from Britain, two from the US (representing Venezuela's interests), and one from Russia, assumed to be neutral. The US represented Venezuela on the panel partly because the Venezuelan government had severed diplomatic ties with Britain. Venezuela reiterated its claim to the district immediately west of the Essequibo River and proposed that the boundary extend from the mouth of the Moruka River southwards to the Cuyuni River, near its confluence with the Mazaruni River, and then along the eastern bank of the Essequibo to the Brazilian border.

On 3 October 1899, the Tribunal ruled largely in favor of Britain. The Schomburgk Line was established as the border between British Guiana and Venezuela, with two deviations. Venezuela received Barima Point at the mouth of the Orinoco, granting it undisputed control of the river and the authority to levy duties on Venezuelan commerce. The second deviation placed the border at the Wenamu River instead of the Cuyuni River, awarding Venezuela significant territory east of the line. However, Britain acquired most of the disputed territory and all of the gold mines.

Venezuelan representatives protested the outcome, alleging that Britain had unduly influenced the Russian tribunal member's decision. However, these protests were largely confined to domestic political circles and international diplomatic arenas.

Immediate Reactions
Immediately after the arbitration ruling in 1899, the U.S. counsels for Venezuela, former U.S. President Benjamin Harrison, Severo Mallet-Prevost, Benjamin F. Tracy, James R. Soley, and José María Rojas, were jointly interviewed and expressed their initial objections to the ruling:

"'Great Britain, up to the time of the intervention of the United States, distinctly refused to arbitrate any portion of the territory east of the Schomburgk line, alleging that its title was unassailable. This territory included the Attacuri River and Point Barima, which is of the greatest value strategically and commercially. The award gives Point Barima, with a strip of land fifty miles long, to Venezuela, which thereby obtains entire control of the Orinoco River. Three thousand square miles in the interior are also awarded to Venezuela. Thus, by a decision in which the British arbitrators concurred, the position taken by Great Britain in 1895 is shown to be unfounded [...] The President of the tribunal in his closing address today had commented upon the unanimity of the present judgment and had referred to it as a proof of the success of the arbitration, but it did not require much intelligence to penetrate behind this superficial statement and to see that the line drawn is a line of compromise and not a line of right. If the British contention was right, the line should have been drawn further west; if it were wrong, the line should have been drawn much further east. There was nothing in the history of the controversy, nor in the legal principle involved, which could adequately explain why the line should be drawn where it had been. So long as arbitration was conducted on such principles, it could not be regarded as a success, at least by those who believe that arbitration should result in the admission of legal rights and not in compromises really diplomatic in character. Venezuela had gained much, but was entitled to much more, and if the arbitrators were unanimous, it must be because their failure to agree would have confirmed Great Britain in the possession of even more territory'. "

The Venezuelan government showed almost immediate disapproval of the 1899 Arbitral Award. As early as 7 October 1899, Venezuela voiced its condemnation of the Award and demanded the renegotiation of its eastern border with British Guiana. On that day, Venezuelan Foreign Minister José Andrade stated that the Arbitral Award was the product of political collusion and should not be adhered to by Venezuela. In accordance with the 1899 Arbitral Award, a mixed British-Venezuelan Boundary Commission began work in 1900 to demarcate the border. Representing Venezuela, Abraham Tirado and Elias Toro surveyed the boundary area in accordance with the Award, alongside two British surveyors, all of whom signed off on the border in 1905.

Renewed Dispute
On 26 October 1899, in a letter to a colleague, Severo Mallet-Prevost, the Official Secretary of the US–Venezuela delegation in the Tribunal of Arbitration, stated that the Arbitral Award was the result of pressures brought on the judges by the President of the Tribunal, Friedrich Martens. After numerous bilateral diplomatic attempts failed to convince the United Kingdom of its seriousness to nullify the award, Venezuela denounced it before the first assembly of the United Nations in 1945.

In 1949, the US jurist Otto Schoenrich gave the Venezuelan government a memorandum written by Mallet-Prevost, which was written in 1944 to be published only after his death. Mallet-Prevost surmised from the private behavior of the judges that there had been a political deal between Russia and Britain, and said that the Russian chair of the panel, Friedrich Martens, had visited Britain with the two British arbitrators in the summer of 1899, and subsequently had offered the two American judges a choice between accepting a unanimous award along the lines ultimately agreed, or a 3 to 2 majority opinion even more favourable to the British. The alternative would have followed the Schomburgk Line entirely, and given the mouth of the Orinoco to the British. Mallet-Prevost said that the American judges and Venezuelan counsel were disgusted at the situation and considered the 3 to 2 option with a strongly worded minority opinion, but ultimately went along with Martens to avoid depriving Venezuela of even more territory. This memorandum provided further motives for Venezuela's contentions that there had in fact been a political deal between the British judges and the Russian judge at the Arbitral Tribunal, and led to Venezuela's revival of its claim to the disputed territory.

By the 1950s, Venezuelan media led grassroots movements demanding the acquisition of the Essequibo. Under the dictatorship of Marcos Pérez Jiménez, the Venezuelan government began plans to invade the Essequibo. President Pérez Jiménez anticipated the invasion of Guyana in 1958, but was ultimately overthrown in the 1958 Venezuelan coup d'état before this was finalized.

United Nations General Assembly Complaint
Venezuela formally raised the issue again at an international level before the United Nations in 1962, four years before Guyana won independence from Britain. On 12 November 1962, Venezuelan foreign minister Marcos Falcón Briceño gave an exposition in the Special Political and Decolonization Committee of the United Nations General Assembly to denounce the 1899 Paris Tribunal Arbitration, citing the Mallet-Prevost Memorandum. Briceño argued that collusion and nullity vices led to the favorable ruling. In his exposition, he stressed that Venezuela considered the Paris Arbitration as null and void because of "acts contrary to good faith" of the British government and the Tribunal members. Said complaints led to the 1966 Geneva Agreement. Venezuela also identified several improprieties and vices in the ruling, especially Ultra Vires. It claimed that the referees exceeded the scope of powers granted by the arbitration treaty in 1897 when it drew the border between British Guiana, Brazil, and Suriname, and also decreed freedom of navigation in the Amacuro and Barima rivers.

The Venezuelan claim of the nullity of the 1899 ruling has been acknowledged by several foreign scholars and jurists, such as J. Gillis Wetter of Sweden, in his work The International Arbitral Process (1979), awarded by the American Society of International Law. After searching the British official archives, Wetter found further evidence of collusion between Britain and Russia, concluding that the ruling was marred by serious procedural and substantive defects, and that it was more a political compromise than a court ruling. Uruguayan jurist Eduardo Jiménez de Aréchaga, former president of the International Court of Justice, came to similar conclusions.

Geneva Agreement
At a meeting in Geneva on 17 February 1966, the governments of British Guiana, the United Kingdom, and Venezuela signed the "Agreement to resolve the controversy over the frontier between Venezuela and British Guiana", best known thereafter as the Geneva Agreement of 1966. The agreement established the regulatory framework to be followed by the parties to resolve the issue. According to the agreement, a Mixed Commission was installed to seek satisfactory solutions for the practical settlement of the border controversy. However, the parties never agreed to implement a solution within this Commission due to differing interpretations of the agreement:


 * Guyana argued that, before starting the negotiations over the border issue, Venezuela should prove that the Arbitral Award of 1899 was null and void. Guyana did not accept that the 1899 decision was invalid, and held that its participation on the commission was only to resolve Venezuela's assertions.
 * Venezuela argued that the Commission did not have a juridical nature or purpose but a deal-making one, so it should go ahead to find "a practical and satisfactory solution", as agreed in the treaty. Venezuela also claimed that the nullity of the Arbitral Award of 1899 was implicit, as otherwise, the existence of the 1966 agreement would be meaningless.

The fifth article of the Geneva Agreement established the status of the disputed territories. The provisions state that no acts or activities taking place on the disputed territories while the Agreement is in force "shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty." The agreement also has a provision prohibiting both nations from pursuing the issue except through official inter-government channels.

In its note of recognition of the independence of Guyana on 26 May 1966, Venezuela stated:

"Venezuela recognises as territory of the new State the one which is located on the east of the right bank of the Essequibo River, and reiterates before the new State, and before the international community, that it expressly reserves its rights of territorial sovereignty over all the zone located on the west bank of the above-mentioned river. Therefore, the Guyana-Essequibo territory over which Venezuela expressly reserves its sovereign rights, limits on the east by the new State of Guyana, through the middle line of the Essequibo River, beginning from its source and on to its mouth in the Atlantic Ocean."

Guyanese Independence and the Occupation of Ankoko Island
Five months after Guyana's independence, Venezuelan troops began their occupation of Ankoko Island and surrounding islands in October 1966, with Venezuelan troops quickly constructing military installations and an airstrip. Subsequently, on the morning of 14 October 1966, Forbes Burnham, as Prime Minister and Minister of External Affairs of Guyana, dispatched a protest to the Foreign Minister of Venezuela, Ignacio Iribarren Borges, demanding the immediate withdrawal of Venezuelan troops and the removal of installations they had established. Venezuelan Minister Ignacio Iribarren Borges replied, stating "the Government of Venezuela rejects the aforementioned protest because Anacoco Island is Venezuelan territory in its entirety, and the Republic of Venezuela has always been in possession of it." The island remained under Venezuelan administration, where a Venezuelan airport and a military base operated.

Rupununi Uprising


The rebellion was primarily led by ranch owners in the Rupununi district who thought their land rights would be revoked by the new government of Prime Minister Forbes Burnham following the 1968 Guyanese general election. The Guyanese government was in the process of creating a commission for issuing land certificates to indigenous families in the area, though the review of 20000 sqmi of land was required.

At a 23 December 1968 meeting, rebels finalized plans for a separated Rupununi state. Venezuela reportedly supported and equipped the Rupununi rebels and their secession movement. * Rebels armed with machine guns and bazookas began their attacks on Lethem on 2 January 1969, first attacking a police station, killing five police officers along with two civilians while the rebels destroyed buildings belonging to the Guyanese government with bazooka fire. The rebels locked citizens in their homes and blocked airfields in Lethem, Annai Good Hope, Karanambo, and Karasabai, attempting to block staging areas for Guyanese troops.

News about the insurrection reached Georgetown by midday, prompting the deployment of policemen and soldiers of the Guyana Defence Force (GDF). GDF troops arrived at an open airstrip 5 mi away from Lethem. As Guyanese soldiers made their approach to the town, the rebels quickly fled, ending the uprising. Academic accounts reported that two or three Amerindians were killed, while rumors reported up to 70 dead. The Guyanese government accused Venezuela of assisting the rebels, accusations that the Venezuelan government rejected. Members of the failed uprising fled to Venezuela for protection after their plans unraveled, with Valerie Hart and her rebels being granted Venezuelan citizenship by birth since they were recognized as being born in the Essequibo disputed territory. The ranchers who organized the rebellion were settled into the Gran Sabana region by the Venezuelan government. On 6 January 1969, Hart was expelled from the United Force, with the political party saying that she was involved "with the rebellion and plot by a foreign power."

Guyana charged 57 individuals with murder. Of the 28 rebels arrested, 18 were released on 24 January 1969 after having their murder charges dropped while the ten remaining individuals were released later. In late February to early March 1969, Amerindian leaders met with Prime Minister Burnham to declare loyalty to the Guyanese government and condemn the reported involvement of Venezuela.

Some Amerindians relocated as a result of the rebellion.

Port of Spain Protocol
In 1970, after the expiration of the Mixed Commission established according to the Geneva Agreement of 1966, Presidents Rafael Caldera and Forbes Burnham signed the Port of Spain Protocol. The signed protocol declared a 12-year moratorium on Venezuela's reclamation of the Essequibo to allow both governments to promote cooperation and understanding while the border claim was in abeyance. The protocol was formally signed by the Minister of Foreign Affairs of Venezuela Aristides Calvani, Guyanese Minister of Foreign Affairs Shridath Ramphal and British High Commissioner to Trinidad and Tobago Roland Hunte. The Parliament of Guyana voted for the agreement on 22 June 1970, with only People's Progressive Party voting against believing that the United Nations should resolve the matter. MPs from almost all parties in the Parliament of Venezuela voiced their sharp criticism of the agreement. Venezuelan maps produced since 1970 show the entire area from the eastern bank of the Essequibo, including the islands in the river, as Venezuelan territory. On some maps, the western Essequibo region is called the "Zone in Reclamation".

In November 1978, more than 900 members of the Peoples Temple cult committed suicide or were forced to commit suicide at Jonestown, a cult settlement which was located in the region.

During the Falklands War between Argentina and the United Kingdom in 1982, Venezuela shared renewed interest to its territorial claims. At the time, a high-level general of the Brazilian Armed Forces warned Venezuela not to attempt any action against Guyana, saying that it would immediately result in a response from the United Kingdom and the United States. Months before the expiration of the Port of Spain Protocol, prominent Venezuelan politician and former interior minister Reinaldo Leandro Mora said in an interview with Venezuelan newspaper El Nacional that if Guyana attempted to develop parts of the Essequibo, that Venezuela would have to "abandon the channels of peaceful negotiation which our national government aspires to and turn to methods involving action."

In 1983, when the Port of Spain Protocol expired, the Venezuelan President Luis Herrera Campins decided to not extend it, resuming his country's effective claim over the territory. Since then, the contacts between Venezuela and Guyana within the provisions of the Treaty of Geneva are under the recommendations of a UN Secretary General's representative which can occasionally be changed with the agreement of both parties. While diplomatic contacts between the two countries and the Secretary General's representative continue, there have been some clashes. The latest personal representative in these efforts is the Norwegian Dag Nylander, appointed in March 2017 by UN Secretary-General António Guterres.

Chávez administration
President Hugo Chávez eased border tensions with Guyana under advice of his mentor Fidel Castro. In 2004, Chávez said, during a visit in Georgetown, Guyana, that he considered the dispute to be finished.

The 2006 changes to the flag of Venezuela included the addition of an eighth star to represent the previously existing Guayana Province and was seen as an attempt for Chávez to establish his legacy.

In September 2011, Guyana made an application before the United Nations' [[Commission on the Limits of the Continental

Shelf]] in order to extend its continental shelf by a further 150 NM. Since the Commission requests that the areas to be considered cannot be subject to any kind of territorial disputes, the Guyanese application disregarded the Venezuelan claim over the Essequibo, by saying that "there are no disputes in the region relevant to this submission of data and information relating to the outer limits of the continental shelf beyond 200 NM." Venezuela sent an objection to the commission, rejecting the Guyanese application and warning that Guyana had proposed a limit for its continental shelf including "the territory west of the Essequibo river, which is the subject of a territorial sovereignty dispute under the Geneva Agreement of 1966 and, within this framework, a matter for the good offices of the Secretary-General of the United Nations". Venezuela also said that Guyana consulted its neighbours Barbados, Suriname and Trinidad and Tobago before making the application, but did not do the same with Venezuela. "Such a lack of consultation with the Bolivarian Republic of Venezuela, serious in itself in that it violates the relevant rules, is inexplicable in so far as the coast whose projection is used by the Republic of Guyana in its attempt to extend the limits forms part of the disputed territory over which Venezuela demands and reiterates its claim to sovereignty rights", said the Venezuelan communiqué.

Oil discovery in Guyana
On 10 October 2013, the Venezuelan Navy detained an oil exploration vessel conducting seafloor surveys on behalf of the government of Guyana. The ship and its crew were escorted to the Venezuelan Margarita Island to be prosecuted. The Guyanese Ministry of Foreign Affairs said the vessel was in Guyanese waters, but its Venezuelan counterpart sent a diplomatic note to Guyana stating that the ship was conducting oil research in Venezuelan waters with no authorization from the country, and demanded an explanation. The vessel, Teknik Perdana, together with its crew, was released the next week, but its captain was charged with violating the Venezuelan exclusive economic zone.

Despite diplomatic protests from Venezuela, the government of Guyana awarded the American oil corporation ExxonMobil a license to drill for oil in the disputed maritime area in early 2016. In May, the government of Guyana announced that ExxonMobil had indeed found promising results in their first round of drilling on the so-called Stabroek Block, an area offshore the Essequibo territory with a size of 26800 km2. The company announced that further drillings would take place in the coming months to better evaluate the potential of the oil field. Venezuela responded to the declaration with a decree issued on 27 May 2015, including the maritime area in dispute in its national marine protection sphere, thus extending the area that the Venezuelan Navy controls into the disputed area. This, in turn, caused the government of Guyana to summon the Venezuelan ambassador for further explanation. The tensions have further intensified since and Guyana withdrew the operating license of Conviasa, the Venezuelan national airline, stranding a plane and passengers in Georgetown.

On 7 January 2021, there was the issuance of Decree No. 4415 by the President of Venezuela, Nicolas Maduro, with the support of Venezuela's National Assembly, which seeks to reinforce Venezuela's claim to Guyana's Essequibo Region and its attendant maritime space.

International Court of Justice
In the case that by December 2017, the UN understood that there was no "significant progress" in resolving the dispute, the Secretary-General of the United Nations António Guterres would intend to refer the case to the International Court of Justice (ICJ), unless the two countries explicitly requested it not to do so. In January 2018, Guterres concluded that the Good Offices Process had not determined a peaceful conclusion and the UN referred the case. Guterres chose to have the controversy settled by the ICJ on whether the 1899 award was valid. On 29 March, Guyana gave a request to the ICJ to solve the territorial dispute. Venezuela proposed that Guyana restore the diplomatic contacts to attempt to find a solution regarding the territorial dispute, arguing that Guterres "exceeded the competences given to him as the Good Offices Figure" and that the decision "contravenes the spirit, purpose and reason of the Geneva Agreement". The Venezuelan government also stated that it did not recognize the jurisdiction of the Court as mandatory. On 19 June, Guyana announced that it would ask the Court to rule in their favor, citing Article 53 of the ICJ Statute, which states that "if any of the two parties does not appear before the tribunal or fails to defend its case, the other party has the right to communicate with the court and to rule in favor of its claim". In July 2018, the government of Venezuela, led by Nicolás Maduro, argued that the ICJ did not hold jurisdiction over the dispute and stated that Venezuela would not participate in the proceedings. The Court stated that Guyana would have until 19 November to present its arguments and Venezuela would have until 18 April 2019 to present its counterarguments. During the Venezuelan presidential crisis, disputed acting President Juan Guaidó and the pro-opposition National Assembly of Venezuela ratified the territorial dispute over the territory. The oral audiences were planned to take place from 23 to 27 March 2020, in which the ICJ would determine if they held jurisdiction in the dispute; however, this was delayed indefinitely due to the worldwide COVID-19 pandemic. Venezuela did not take part in the hearings which were rescheduled for 30 June. On 18 December 2020, the Court ruled that it had jurisdiction and accepted the case. On 8 March 2021, Venezuela was given until 8 March 2023 to submit a counter-memorial.

On 18 September 2020, the United States announced that it would join Guyana on sea patrols in the area. The first agreement in the negotiations between the Maduro government and the Venezuelan opposition in Mexico in September 2021 was to act jointly in the claim of Venezuelan sovereignty over Essequibo. The ICJ ruled that it had jurisdiction to determine the territorial dispute in April 2023.

Venezuelan consultative referendum
On 31 October 2023, the government of Guyana filed a request with the ICJ requesting intervention against a proposed referendum approved by the Venezuelan National Electoral Council on 23 October 2023, asking to support its position in the dispute, arguing that the referendum served as a pretext for the Venezuelan government to abandon negotiations with Guyana. The proposed referendum was condemned by the Commonwealth of Nations and Caribbean Community (CARICOM), who both issued statements in support of Guyana and the agreed ICJ process for dispute resolution. In response to the increased tensions, the Brazilian military on 29 November 2023 "intensified defensive actions" along its northern border. On 1 December 2023, the ICJ ordered Venezuela to not make any attempts to disrupt the current territory controlled by Guyana until the court makes a later determination. The referendum took place on 3 December, and the National Electoral Council initially reported that Venezuelans voted "yes" more than 95% of the time on each of the five questions on the ballot.

There has been no similar consultation conducted, by either Venezuela or Guyana, with the indigenous people of the region.

Venezuelan Administrative Laws
According to some interpretations of Venezuelan legislation, Essequiba Guyana is an integral part of the jurisdiction of the states of Bolívar and Delta Amacuro, whose common boundary runs along the cusp of the Imataka mountain range. The state of Bolívar, in its constitution, establishes the following:

The original territory of what is now the state of Delta Amacuro extends from the Orinoco delta to the Esequibo River. The information website of the governor's office of this state states the following about its territoriality:

Historically in Venezuela, the central power (government and other Venezuelan state agencies) has been directly in charge of the treatment of the case of Guayana Esequiba, leaving the local governors' and mayors' offices with very little participation and power of action. A special and differentiated treatment is given to the jurisdictions of these national states, which do not usually include in their maps their territorial portion within the Guayana Esequiba, although in the national maps of the country the inclusion of the area under claim is mandatory. This has led some people to erroneously think that the Guayana Esequiba is a new Venezuelan state or federal territory.

In 1999, when the new Venezuelan magna carta was enacted, Article 10 of the Constitution of the Venezuela established the following as Venezuelan territory:

In August 2015, some deputies of the Venezuelan National Assembly proposed the creation of state number 25 (Estado Esequibo) uniting the territory of Guayana Esequiba (159,500 square kilometers) and the Sifontes Municipality (24,393 square kilometers), with capital in Tumeremo, the latter territory currently under the jurisdiction of the state of Bolivar. The proposal was officially introduced before the secretariat of the National Assembly, but was not approved.
