Ilagan, officially the City of Ilagan (Siudad nat Ilagan; Siudad ti Ilagan; Lungsod ng Ilagan), is a 1st class component city and capital of the province of Isabela, Philippines. According to the 2020 census, it has a population of 158,218 people making it the most populous city in the province. As of 2022, it also had the most number of voters in the province with 101,050 electorates.

With a total land area of 116626 ha, it is the largest city on the island of Luzon and the fourth largest city in land area in the Philippines, after Davao City, Puerto Princesa, and Zamboanga City.

Etymology
From an inversion of the Ibanag word nagali reversed to ilagan which means move or transfer in the English language, due to the relocation of the site of the capital from Naguilian Baculod to its present site in barangay San Vicente. The move was due to the economy and security of the town. Another etymology, according to Fr. Julian Malumbres, Ilagan derived its name from the word laga, an Ibanag word for smallpox during the town's founding in 1686 when the disease was widespread.

Early history
The town was then called by its native Gaddang settlers as Bolo during the pre-Spanish conquest era. It was one of the populous settlements during that period and the site of the vast tobacco plantation in the region making it one of the most important economic areas in northern Luzon.

Spanish colonial era
In 1581, Governor-General Gonzalo Ronquillo de Peñalosa sent Capt. Juan Pablo Carreon to explore Cagayan Valley as well as to establish missions. Among the Spanish missionaries who penetrated deeply into the region was Pedro Jimenez, who founded Ilagan.

The town of Bolo was founded by the Dominicans in 1619 in honor of Saint Ferdinand of Castile. The old Bolo was situated on the western side of Cagayan River in what is known today as barangay Naguilian-Baculod. The cultural shock brought by the dominating social and economic regulations introduced by the Spanish authorities propelled the natives to dissent in the Mallig and the Ilagan-Tumauini territories in what was known as the Gaddang Revolution. The natives abandoned their settlement after burning their church and houses until 1622 when the Spanish government pardoned and exempted them from paying tribute within three years. After the Gaddang revolt, the natives re-established their settlement upon the efforts of Fr. Pedro Jimenez in 1678 on the east side of the river thereby giving the legendary name for Ilagan which is the reverse of the word nagali meaning move or transfer. The Dominicans accepted the settlement as an ecclesiastical mission given the name San Fernando de Ilagan in honor of its patron, Saint Ferdinand of Castile.

Foundation
On May 4, 1686, Ilagan was founded and missionaries converted the natives to Catholicism. Ilagan was made the capital town of Cagayan Valley when Brig. Manuel Sanchez Mira was then the governor of the whole territory.

In 1763, Ilagan was the scene of the revolt led by Dabo and Juan Marayag against the collection of tribute, the enforcement of tobacco monopoly committed by the friars during the Spanish colonization.

On May 1, 1856, Ilagan became the capital town when Isabela de Luzon was founded.

American colonial era
Present-day Ilagan is an area that was detached from the old province of Nueva Vizcaya. The first municipal president of the town, Rafael Maramag, added luster to the history of his hometown by becoming the first governor of the province of Isabela after its reorganization by the Americans in 1901.

On August 4, 1901, the American occupation under the United States-Philippine Commission enacted the Provincial Government Act 210 that re-established Isabela and other provinces in the Philippines. Rafael Maramag, a former municipal president (mayor) of Ilagan was appointed as the first governor. The act then re-established Ilagan as the provincial capital.

On November 13, 1925, Gaffud approved a resolution filed by all Municipal Presidents of the Isabela (the counterpart of the present-day Mayor's League) following a four-day convention. The resolution called for the erection of a monument in honor of the country's National Hero José Rizal in Ilagan public plaza located in barangay Bagumbayan.

Japanese occupation
The fortunes of Isabela as a province and Ilagan as a town followed a similar path to the rest of the country's history as a commonwealth nation and as a free republic in 1942, the Japanese occupation, liberation, political and military independence to this day.

On June 19, 1945, Ilagan was liberated from the Japanese Army as part of the liberation campaign with the combined forces of 14th Infantry, United States Army Forces in the Philippines – Northern Luzon (USAFIP-NL), under the command of Lt Col. Romulo A. Manriquez, and the 37th Division of the U.S. Sixth Army against the Japanese.

During this era, a man-made tunnel was constructed from the sweat and blood of detained Ilagueños and it is now a tourist destination in the city. The tunnels are believed to have served as headquarters of the Japanese soldiers.

The Postwar era
By the turn of the 1950s, the new Poblacion was located uphill from the old Saint Ferdinand Parish Church, formerly known as Saint Ferdinand Cathedral in barangay Bagumbayan to barangay San Vicente, which is the site of the current City Hall.

The Martial Law era
When Ferdinand Marcos' September 1972 declaration of Martial law began 14 years of authoritarian rule, the province of Isabela, including the municipality of Ilagan became a center of both conflict and protest when Marcos cronies Danding Cojuangco and Antonio Carag managed to block a Spanish-era grant which was supposed to see the return of Hacienda San Antonio and Hacienda Santa Isabel in Ilagan to local farmers. Cojuangco and Carag purchased the two haciendas themselves, displacing tens of thousands of farmers who were supposed to get those lands back a hundred years after the Spanish acquired them.

In its desire to serve its parishioners, the Roman Catholic Diocese of Ilagan hosted a Social Action Center which would help the farmers. In the Social Action Center's newsletter, the "Courier," researcher Sabino Padilla Jr. documented and exposed the ways by which Cojuangco, Carag, the provincial government, and the military harassed the farmers who were supposed to get the land. This all led to a protest march in joined by 12,000 protesters from all over Isabela, and eventually, for 4,000 farmers to finally get the titles to their land. But it also earned the ire of the administration.

In 1982, Padilla and 12 others were arrested by the regime and jailed under poor conditions at the Bayombong, Nueva Vizcaya Stockade of the Philippine Constabulary until almost the end of the Marcos regime.

In 1983, soldiers went as far as to raid the residence of the Bishop of Ilagan, Miguel Purugganan, in search of alleged rebels and firearms. They found none but continued to keep Bishop Puruggananan and the church workers under him under military surveillance.

Cityhood
On February 2, 1998, congress passed Republic Act 8474 which sought to convert Ilagan into a city. But the plebiscite held on March 14, 1999, turned down its bid for cityhood. The majority of the people voted no in that event under the mayoralty of Mercedes P. Uy.

On March 2, 2005, House bill no. 3847 was filed and approved by the house and transmitted for the cityhood of Ilagan but remained pending concurrence in the senate. The bill did not go through when mayor Delfinito C. Albano was gunned down by three unidentified men in the night of June 27, 2006, in Quezon City. The campaign used the term C-U-DAD Ilagan for the cityhood status of Ilagan.

On February 27, 2012, Ilagan renewed its bid for cityhood as sponsored by House bill no. 5917. Local officials of the town expressed support for the town's conversion into a city. On May 22, 2012, the congress approved the cityhood bill of Ilagan on its House resolution no. 144 and was signed by then President Benigno Aquino III on June 21, 2012. Plebiscite was held on August 11, 2012, with a majority of votes voting yes under the leadership of Josemarie L. Diaz. By virtue of Republic Act 10169, Ilagan was then proclaimed as a new component city, the third in the province of Isabela and the fourth in Cagayan Valley on the same day by COMELEC Commissioner Armando Velasco.

Contemporary
On August 28, 2019, the city government created the Ilagan Development Authority (ILAGANDA) which is aimed to transform Ilagan into a liveable city in the year 2030.

On November 25-26, 2023, the City of Ilagan hosted the biggest and largest serbisyo caravan in the country, the Bagong Pilipinas Serbisyo Fair held at the City of Ilagan Sports Complex and Isabela National High School. The event saw the first time that the BPSF program went to Cagayan Valley, marking its eighth installment nationwide.

Among the lined-up activities are Rise Up Financing, Online Business Name Registration, Barangay Micro Business Name Registration, One Town, One Product (OTOP) Mini Fair, Diskwento Caravan, Product Standard Showcase, and Negosyo Center Business Counseling Services. Under the initiative, Isabela residents received P152 million worth of cash, while a total of P500 million went to programs and services. The program benefited at least 100,000 recipients, with a total of 26 government agencies participating in the event, providing over 195 services. Among the services included is the Department of Social Welfare and Development’s (DSWD) Assistance to Individuals in Crisis Situations (AICS) program, which provided a provincial wide payout in the three cities and 34 municipalities of the province of Isabela. AICS assisted more than 42,000 individuals amounting to a total of P140 million in payout which included assistance for Agrarian Reform Beneficiaries (ARBs), Persons with Disabilities (PWDs), Indigenous Peoples (IPs), teachers, the transport sector, and fishermen; and collaborate with partner agencies. The BPSF also included other province-wide activities such as scholarship programs from the Technical Education and Skills Development Authority (TESDA) and the Commission on Higher Education (CHED). Other activities included livelihood assistance for various sectors in pre-identified eligible recipients across Isabela. The Department of Health (DOH) shared their Lab for All program, or the giving of free medical services closer to the people. While the Department of Agriculture (DA), spearheaded the distribution of financial assistance for farmers, seeds and fertilizers, and farm equipments and machineries. Products of farmers and fishermen were also on sale through the KADIWA ng Pangulo as a way to promote locally produced products. All of the products displayed were made affordable, fresh, and pesticide-safe for the consumers. The Bureau of Fisheries and Aquatic Resources (BFAR) also turned over fish cages, fish feeds, and fingerlings for the distribution and sale of seafood. Agencies like the Department of Agrarian Reform (DAR), Department of Labor and Employment (DOLE), Department of Science and Technology (DOST), Department of Environment and Natural Resources (DENR), Philippine Coconut Authority (PCA), National Food Authority (NFA), and the Public Attorney’s Office (PAO) also provided livelihood, legal, and other relevant social services to the recipients. Other regulatory functions of the Philippine National Police (PNP), Department of Foreign Affairs (DFA), Land Transportation Office (LTO), National Bureau of Investigation (NBI), Philippine Statistics Authority (PSA), Professional Regulation Commission (PRC), Social Security System (SSS), PhilHealth, Government Service Insurance System (GSIS), and the Bureau of Internal Revenue (BIR) also extended their programs and services during the two-day caravan.

Climate
Ilagan has a tropical savanna climate (Köppen Aw) with consistently hot temperatures year-round, a dry season from January to April, and a wet season from May to December.

Land
Of the total 1,166.26 km2 land area of Ilagan; 31% are agricultural, 36% are forest areas, and the remaining 33% are built-up areas and open grassland areas that are available for industrial, commercial and residential uses.

Ethnicity
Ilagueños today reflect a combination of indigenous, Chinese, and Hispanic descent. The core community was composed of tribes notably the Agta, Ibanag, Gaddang, Yogad, and Kalinga which mirrors the habitation of the Philippines believed to have started 26,000 years ago with various strains of Aetas, then Indonesians coming 5,000 years ago and the Malays in droves starting 200 years B.C. up to 1500 A.D. Trade and cultural relations with Chinese preceded the 16th-century incursion of the Spaniards. Ilocanos who already developed their own distinct traits were recorded to have migrated massively in the 19th century owing to the accessibility of the land and vast opportunities in the area straddling the present-day provinces of Cagayan and Nueva Vizcaya. It was proclaimed a province by a Royal Decree and named Isabela de Luzon on the first day of May in 1856.

Languages
There are three native languages in Ilagan: Ibanag, Ilocano, and Tagalog, which make it a multilingual city. English is used primarily in communication for government publications, local newsprints, road signs, and commercial signs, and in doing official business transactions in the city.

Population
As of the 2020 census, Imelda Bliss Village is the most populous barangay with 7,951 people while Carikkikan Sur is the least populous barangay with just 208 people.

The rapid increase of the population in Ilagan is attributed to the current growth of economic activities especially in the sectors of Commerce, Industry, Agriculture, and Housing. Ilagan is one of the 145 emerging cities in the Philippines with more than 100,000 residents. Statistics from the Philippine Statistics Authority show that Ilagan had a population 131,24311 in 2007, which increased to 135,174 people in the 2010 census making Ilagan as the most populous city in the province of Isabela and the second in Cagayan Valley after Tuguegarao. In the 2020 census, the population of Ilagan, was 158,218 people, with a density of undefined PD/km2.

Catholicism
Ilagan's population is predominantly Roman Catholic. The Diocese of Ilagan has 39 catholic churches all over the province of Isabela. Its former seat was in Saint Ferdinand Parish, then it is now transferred to the Cathedral of Saint Michael the Archangel in Gamu, Isabela. The Saint Ferdinand Parish was built in a baroque style in 1612and is located in barangay Bagumbayan.

Others
There are also Protestants, Baptist, Church of Christ, Adventists, Born Again groups, Victory Christian Fellowship, Latter Day Saints, Jehovah's Witnesses, Islam, and Philippine-based groups like Iglesia ni Cristo, and Members Church of God International (MCGI) that account to the city's population. These religious organizations have their own temples and churches sparsely located in the city.

Economy
At present, Ilagan has been one of the fastest-growing economies in the province of Isabela as well as in the whole Cagayan Valley over the past years. The city is the primary growth center and investment hub of the region due to the rapid commercialization and stabilization of the different sectors involved in its economy.

The transformation of Ilagan into a fast-growing city in Cagayan Valley became evident upon the assumption into office of then Mayor Josemarie L. Diaz, the re-structuring of the economic landscape of the city and the eventual transformation of its business climate into a business-friendly environment successfully lured multi-national companies in investing their capitals into its market. The economic boom began to engulf Ilagan with the entry of eight banks and financial institutions in just several months.

The Local Government of Ilagan responded positively to these developments by the enactment of legislative measures including the provision of the Investment Incentive Code which provided for tax incentives to investments. These measures eventually opened the floodgates for big investments to enter the local market that included the establishments of malls like the Xentro Mall (formerly called Northstar Mall) and Talavera Square Mall that house the Savemore, Robinsons Supermarket, Puregold, Jollibee, McDonald's, Red Ribbon, Goldilocks, Mang Inasal, Greenwich, Chowking, Ace Hardware, D.I.Y. Hardware, Pandayan Bookshop,  Watsons, MR.DIY, Mercury Drug, 7-Eleven,  and many other stores.

There are also thousands of commercial establishments composed of distributors, retail and wholesale. Pawnshops, lending companies, insurance agencies, cooperatives, and other financial institutions are spread all over the city.

Agriculture, fishery, and animal industry
Agriculture and fishery remain the main backbone of Ilagan's economy. There are almost 23,803 hectares that are cultivated land and 314 hectares are utilized for fish culture. However, the suitable farm area of Ilagan is 32,153.19 hectares with potential for crops, livestock, and fish production. This figure shows that a significant percentage (24.99%) is not being fully utilized for agricultural production leaving them idle and underutilized.

Most of the industries in the city are agri-based. For the last ten years, there has been a great number of local investment in poultry and hog raising. There are seven poultry contract growers and 33 small and medium-scale hog raisers in Ilagan. Other support facilities, warehouses, and small rice mills, strategically located in different barangays of Ilagan address the storage needs of farmers during the harvest season.

Of all cities in the country, Ilagan ranks as the top producer of corn. As an agriculture-based city, it produces ample supply of corn, rice, vegetables, and legumes. Fruits like bananas are year-round products, especially in the mountainous areas of the city. Ilagan also produces seasonal fruits such as mangoes and pomelo.

The Cagayan Valley Research Center (CVRC) is an attached agency of the Department of Agriculture (DA) that serves as the primary plant breeding institution in Cagayan Valley. It is one of the Bureau of Agricultural Research’s active partners in research and development in the region. It is located in Barangay San Felipe along Maharlika Highway. Ilagan has rich forest resources. Hectares of forest land are strictly protected by authorities like the Department of Environment and Natural Resources (DENR), several NGOs, and the Local Government Unit.

In 2018, the Department of Agriculture Regional Field Office No. 02 has pledged to intensify the promotion of mushroom production in Cagayan Valley through the establishment of the region’s research and development center for the mushroom industry. The DA’s Bureau of Agricultural Research (BAR) funded the construction of the Cagayan Valley Mushroom Research and Development Center which aims to support the agency’s activities on processing of agricultural waste into sustainable and competitive mushroom production towards food security and safety in the region. The Department of Agriculture, through its research centers and experiment stations, had already initiated trainings on production and processing to interested farmers, cooperatives and local government units. The modern facility is located at the DA-Regional Crop Protection Center (RCPC) in Barangay San Vicente. Its inauguration is part of DA-initiated Panagdadapun and first Makan Festival. It was done simultaneously with the inauguration of Luzon’s first-of-a-kind Plant Genetic Resources (PGR) Center that was launched on May 16, 2018.

The Department of Agriculture Regional Field Office 2 (DA-RFO2) and the city government of Ilagan had agreed to establish an i-Corn Complex worth P199.2 million. The agreement was reached after a consultation meeting led by the DA Region 2 officials and representatives from other concerned government agencies. The Department of Agriculture will provide P107 million while the city government of Ilagan will provide P92.2 million for the said complex that will serve as a one-stop agri-commercial center once completed. The i-Corn Complex will serve Ilagueño corn farmers including those from Isabela and the rest of Cagayan Valley. The establishment of the facility is also aimed to solve problems in corn production, particularly drying during the wet season. The construction of the corn complex is in support of the Agriculture and Fisheries Modernization Act (AFMA), which aims to strengthen the agri-fisheries sector in a modernized perspective to attain food security, poverty alleviation, income enhancement and profitability, global competitiveness, and sustainability. The complex is designed to be used as a post-harvest, processing, and research facility that will ensure product quality and thus boost the income of farmers. It is expected to be operational by February 2024 with the operation of the Corn Innovation Center whose construction and implementation started in August 2023. The mechanical drying facility as one of its components will help farmers cope with losses and damage during calamities. The said corn complex facility is located in Barangay Marana 1st, where the city government donated the lot for the construction.

The Corn Innovation Center in Barangay Marana 1st is one of the flagship agri-support projects of the City Government of Ilagan’s thrust for the next three years on food sufficiency and producing finished corn products as Ilagan affirms its Corn Capital title. The groundbreaking ceremony was held on July 12, 2022 led by top officials and executives of the city of government alongside officials and representatives from the Department of Agriculture Regional Office 2 and Bureau of Agricultural Research. The City Government of Ilagan pledged P10 Million as its counterpart, in addition to the P10 Million from the Department of Agriculture itself. The facility will be utilized as a training center for farmers. It is also envisioned to be the city’s Tech-Hub Demonstration Center to showcase new technological advancements in corn processing and other commodities. The completion of its construction is set by the first quarter of 2024.

On December 2, 2020, then Agriculture Sec. William Dar attended the Inauguration of the P500 million 2,400 Sow level Swine Breeding Complex of the Thai-based Agro-Industrial Company, Charoen Pokphand Foods Philippines, Inc. in partnership with Sagittarian Agricultural Philippines Incorporated in Barangay Santa Victoria.

Thai conglomerate Charoen Pokphand Group Company Ltd. through its Philippine subsidiary, Charoen Pokphand Foods Philippines, Inc. in partnership with homegrown company Sagittarian Agricultural Philippines, Inc. and the Land Bank of the Philippines is pouring in more than P1.8 billion worth of investments for the establishment of its huge animal feeds milling facility in Ilagan. The construction of the project is expected to begin by the 3rd quarter of 2024. The feed mill will be situated in a 10-hectare land that the company acquired in Barangay Cabannungan 2nd. It will be the biggest feed mill of its kind in Northern Luzon as their Central Luzon operation is already saturated. Ilagan is known as the largest producer of yellow corn used for animal feed, earning its title as the Corn Capital of the Philippines in 2015. The average production of quality corn in Ilagan is at approximately 200,000 metric tons per year coming from its 33,500 hectares of production areas which will definitely compensate the minimum requirement for the raw materials needed by the feed mill once it becomes operational. The groundbreaking ceremony of the City of Ilagan Feed Mill Complex and the signing of the Memorandum of Agreement between Charoen Pokphand Foods, Sagittarian Agricultural Phils., Inc. and Kasetphand Group was held on May 17, 2024. This kind of joint venture between the government and private sector is essential for the delivery of basic services and business matching opportunities specifically for corn farmers who will be the primary recipient of the project. It also aims to generate more jobs and employment opportunities for Ilagueños and to spur development in the countryside.

Tobacco industry
Ilagan became one of the largest producers of tobacco during the Spanish time. The tobacco monopoly caused the valley to languish in poverty from 1785 to 1797.

In Ilagan, the Compañía General de Tabacos de Filipinas also known as La Tabacalera was established in 1881 and produced the famous La Flor de la Isabela which was the largest company of its kind in the world at that time. The Tabacalera acquired two haciendas in Ilagan which were Hacienda San Antonio and Hacienda Santa Isabel. The majority of the western barangays of the municipality are planting tobacco other than rice, corn, and high-value crops. The National Tobacco Administration is the attached agency under the Department of Agriculture that is mandated to conduct series of efficacy trials, scientific experiments and tests on new agricultural products, inputs, systems, and processes being introduced. They recommend and certify the applicability and efficacy of the recommended tobacco technologies. Its provincial field office is located at Barangay Osmeña.
