Marvão

Marvão is a municipality in Portalegre District in Portugal. The population in 2020 was 2,972 (and dropping at a rate of around one inhabitant per week), in an area of 154.90 km2. The present Mayor is Luís Vitorino, elected by the Social Democratic Party. The municipal holiday is September 8.

Perched on a quartzite crag of the Serra de São Mamede, Marvão's name is derived from an 8th-century Muwallad rebel, named Ibn Marwan. Ibn Marwan, who constructed the Castle of Marvão - likely on the site of an earlier Roman watchtower - as a power base when establishing an independent statelet ("emirate", duchy) - covering much of modern-day Portugal - during the Emirate of Cordoba (884-931 CE). The castle and walled village were further fortified through the centuries, notably under Sancho II of Portugal (13th century) and Denis of Portugal.

The village has generated significant tourist interest in recent years. It was included in the #1 New York Times bestselling book, 1000 Places to see Before you Die. Nobel Prize-winning author José Saramago wrote of the village, "From Marvão one can see the entire land ... It is understandable that from this place, high up in the keep at Marvão Castle, visitors may respectfully murmur, 'How great is the world'."

In the 1950s, author Huldine V. Beamish wrote of Marvão, "There is an atmosphere about the district (of Marvão) that is very ancient. At times you have the same peculiar feelings as those evoked by Stonehenge and that amazing druid monument at Callernish in the Isle of Lewis. Picking your way along the steep stony pathways, you would not be at all surprised to meet a Phoenician trader or Roman Soldier. It would be the most natural thing in the world."

An annual international classical music festival, under the artistic direction of German conductor Christoph Poppen, was launched in Marvão in July 2014. The village also hosts an international film festival, Periferías, in August each year. Other annual festivals in Marvão include 'Al-Mossassa'- a celebration of the town's Moorish past, held jointly with the Spanish city of Badajoz (also founded by Ibn Marwan) - in early October, plus a major Chestnut Festival in early November.

Parishes
Administratively, the municipality is divided into 4 civil parishes (freguesias):
 * Beirã
 * Santa Maria de Marvão
 * Santo António das Areias
 * São Salvador da Aramenha

History
Commanding views across the Tagus basin and Serra de Estrela to the north, the fortified rock of Marvão has been a site of significant strategic importance since the earliest human settlements.

Today, lying on the 'raia' that divides Portugal and Spain, Marvão has consistently stood on a frontier zone between peoples: Celtici, Vettones and Lusitani (4th-2nd century BCE); Lusitanians and the Romans of Hispania Ulterior (2nd-1st century BCE); migratory Suevi, Alans, Vandals and Visigoths (5th-7th century CE); conquering moors and Visigoths (8th century); muwallad rebels and the Cordoban emirate (9th-10th century); Portuguese nation-builders and Moors (12th-13th century); Templars and Hospitallers (12th-14th century); Portuguese and Castilians (12th century-present day); Liberals and Absolutists (19th century); the fascist regimes of Salazar and Franco (20th century).

Marvão's natural assets have contributed to the 'uniqueness' of this remote village as perceived by visitors today: (i) as nigh-impregnable 'eagle's nest' fortress - perched high on a granite crag, and bordered on the south and west by the Sever river; (ii) as vital lookout-point towards the Alcántara Bridge (70 km away), a wide stretch of the Tagus basin and the Serra de Estrela; (iii) as a gateway to Portugal from Spain via the Porta da Espada ('Sword Gate') mountain pass of the Serra de São Mamede.

Prehistory
The earliest dolmens in southern Portugal date from c. 4800 BCE, and this culture lasted into the Bronze Age (2000 BCE) and beyond into the Iron Age. In and around Marvão, there exists a high concentration of dolmens, rock-hewn tombs, passage mounds and megaliths, dated to the 3rd millennium BCE.

Together with the Sever-valley sites around the nearby towns of Castelo de Vide and Valencia de Alcântara (in Spain), these form one of the densest clusters of megalithic sites in Europe. Among the 200+ neolithic, Bronze and Iron Age monuments within a 25 km range of Marvão is the 7.15m high Menhir of Meada (the largest on the Iberian peninsula), oriented to be visible from the northernmost promontory of Marvão's rock (possibly based on an alignment with the lunar calendar).

Other notable sites are the Coureleiros complex of dolmens near Castelo de Vide, the Vidais dolmen (Castelo Velho) of Santo Antonio das Areias and the Las Lanchas dolmen complex of Valencia de Alcântara.

Archaeological finds from this era include substantial grave goods, for example anthropomorphic idol plaques, arrowheads and axes, and jewellery. A database of idol plaques - the Engraved Stone Plaque Registry and Inquiry Tool - lists 16 plaques found in Marvão, 14 in Castelo de Vide, and 28 in Valencia de Alcântara.

It is speculative to comment on the population of Marvão at this time. Many carved tombs and burial chambers dot the granite boulders of the landscape around Marvão, suggesting small-scale farming settlements, and some cultural emphasis on burial rites and the afterlife. Excavations of dolmens (e.g. the Cavalinhas dolmen) reveal foetal-position buried skeletons, and grave goods including weaponry (axes, arrowheads), jewellery (necklaces), ceramics and stone idols. Cave art and engravings in the Tagus valley (40 km north of Marvão: 40,000 items) point to a developed culture based on prehistoric norms of agriculture, hunting and transhumance.

Further, ideograms - notably, repetitions of spirals - point to both abstract ideas, religious observance, and some astronomical knowledge of lunar and solar cycles. Decorative objects - rock crystal arrowheads, floral- and zig-zagged patterned stones (pedras de raio) and ceramics, deity sculptures - also suggest the development of local systems of craftsmanship, hierarchy, magic and celebration. Recent studies of idol plaques have speculated that they depict some kind of owl deity, with their engravings acting as a means to identify the individual buried by clan, marriage and lineage.

Pre-Roman era: Lusitani and Celtici


The Iberian peninsula saw migrations of Celtic tribes from central Europe during the 6th–4th century BCE. The site of modern-day Marvão would have stood on the northern periphery of the territory of the Celtici tribe, which stretched from the Tagus to Guadiana rivers, and beyond to the Algarve and today's Huelva province in Andalucia. The area falls within the northernmost limits of the Tartessian paleohispanic language and culture, centred on Huelva in Spain, in decay throughout this period as Celticisation took place. Tartessians were the creators of the Southwestern script, one of the earliest written languages in Europe. A renowned gold hoard from the Tartessian period, the Tesoro de Aliseda was discovered in nearby Aliseda (Cáceres province), while a gold bracelet discovered in nearby São Julião (Portalegre) - sold at auction in 2013 - suggests that local tribes were relatively wealthy. The migration of the Celtici is considered part of a third or fourth wave of Celts in the 4th century BCE: this migration occurred across modern-day Aragon and into modern-day Extremadura and Alentejo, displacing the proto-Celt Lusitanians who dominated the lands north of the Tagus, and skirting the Vettones lands that stretched from Zamora to Castelo Branco.

So in the three centuries prior to Roman conquest (3rd–1st century BCE), Marvão stood at a junction of the Celtici, Lusitani, and Vettones tribes, and its dominant strategic position offered line-of-sight long into the territories of all three tribes. A locally found head of a pig-like sculpture from the Verraco (Portuguese: berrão) culture of the Vettones is displayed in Marvão's museum.

Given their strategic location, the Serra de São Mamede and Spain's Sierra de San Pedro – in particular the dominant escarpments of Marvão on the northernmost tip and Alburquerque on the southernmost tip - are likely to have played a role in conflicts between Celtiberians and Romans. While Marvão lies north of the territories of Carthaginian Iberia – which by 218 BCE reached across Southern Iberia up to the river Guadiana, the area is likely to have been crossed during the 230s and 220–218 BCE during Carthaginian slave-raiding and mercenary-recruitment campaigns focused on the Tagus valley (e.g. Hamilcar Barca's Tagus encampment at Cartaxo) and along what later became Ruta de la Plata: Iberian manpower was to play a role in the Punic Wars.

In the 2nd century BCE, Roman might asserted itself following the Punic Wars, yet progress was slow in these border regions. A series of bloody revolts and wars (195–135 BCE) pitted the Lusitanians and Vettones - most notably under the guerrilla fighter and hero Viriatus – against the expansionist Roman colonisers of Hispania Ulterior. While nominally the area was under Roman control from the early 130s BCE, for a century an unstable war zone spread from the Serra de Estrela-Tagus basin (seen from Marvão) and the Extremaduran plains between Alburquerque and the Sierra de Aracena.

Some speculation has focused on whether 'choças', the traditional circular-floorplan barns with broom-thatched roofs – found throughout Marvão, most dating from the post-medieval period - are a vernacular survivor from these Celtic times. The 'choças' of Marvão follow the rudimentary pattern of roundhouses found throughout Celtic settlements in Europe. Similarly, a number of corbelled circular drystone shelters, with a false cupola (Portuguese: chafurdão) in Marvão reflect similar Iron Age structures across Southern Europe (e.g. the Spanish bombo and Croatian trim'') associated with the terracing and clearance of rocky land for farming. The Vettones culture was renowned for its cattle-rearing and Verraco (Portuguese: berrão) pig-like sculptures: porco preto rearing remains dominant in local agriculture and cuisine.

The Roman era: Ammaia
After considerable resistance from Lusitanian tribes in the 2nd-1st century BCE, the Romans gained a tentative foothold over the areas south of the Tagus and north of the Sierra Morena during the 130s BCE. While early encampments had been made in Cáceres from 139 BCE (Castra Servilia) and in Almourol (in the Tagus valley) from 138 BCE, Roman progress was only made in fits and starts. Lusitanian rebellions - notably the Sertorian War (80-72 BCE) - hampered progress, with effective Roman rule being achieved in the area under Julius Caesar's campaigns in 61-60 BCE. Throughout this period, the terrain of the Serra de São Mamede is likely to have served as ideal base for guerrilla warfare, ambushes and smuggling. Lusitania only became a fully-fledged province under Augustus in 27 BCE, with the pax Romana heralding five centuries of strong urban development across southwest Iberia.

In Marvão, gradual consolidation of Roman power led to the establishment of a substantial Roman town in the 1st century CE: Ammaia. Occupying up to 25 hectares, and with a population exceeding modern-day Marvão (5000-6000 inhabitants), Ammaia occupied the site of the present-day parish of São Salvador da Aramenha. The town flourished between the 1st century BCE and the collapse of the Roman empire in the 5th century CE.

Ammaia's location on the river Sever was a waypoint on west–east trading routes, linking towns such as Scallabis (Santarém), Eboracum (Évora), Olisipo (Lisbon) and Miróbriga (Santiago de Cacém) to the provincial capital Emerita Augusta (present-day Mérida) via Norba Caesarina (Cáceres). The mountain of Marvão would also have served as a watchtower providing line-of-sight to the vitally-important Roman bridge at Alcántara. Local agricultural production (olives, wine, figs, cattle) was supplemented by horse-breeding, pottery, and mining activity - notably rock crystal and quartz from veins on the Marvão mountain, together with open cast gold mining on the Tagus to the north. Roman Ammaia saw the development of improved irrigation and terracing across the Marvão mountain. Chestnut cultivation - replacing the local dominance of oak - is likely to have been introduced at this time. Much of the terracing and ancient watercourses on the Marvão mountain date from this era.

Limited excavations at Ammaia in the past two decades - albeit covering a mere 3000 m² of the town's area - have revealed a successful, expanding provincial town that included running water, a forum, baths, a bridge over the river Sever (near today's 'Ponte Velha'), and monumental gates (one gate was removed to Castelo de Vide in the 18th century, yet sadly dynamited in 1890). The Alto Alentejo region, meanwhile, was criss-crossed with efficient Roman roads, providing wider links to the Empire. Fine wares found at Ammaia suggest that the local Ammaia nobility had access to luxury glassware and jewellery, while archaeology has revealed that marble for the forum was imported from across the Empire. The high quality, for example, of the 'Mosaico das Musas' - from a Roman villa in nearby Monforte (4th century BCE) - points to the abundant riches to be made as an Alentejo landowner in the Roman era. Sadly, many artifacts from Ammaia - in particular a series of marble sculptures - were removed during the 19th and 20th centuries, notably by the Anglo-Portuguese Robinson family. These items are now in collections such as those of the British Museum.

The post-Roman era: decline of Ammaia, Alans, Suevi and the Visigoths
During the 5th-7th century, the invasion of Roman Iberia by a succession of tribes from Central Europe - the Vandals, Suevi, Alans and Visigoths - left an indelible mark on Marvão and Lusitania as a whole. Hispano-Roman urban centres across Iberia suffered two centuries of instability, violence and depopulation, and many towns fell into ruin. Ammaia was no exception.

Historic documentation for the invasion of towns around Mérida province is poor, yet these were clearly difficult times for Ammaia. It is likely that the years 409-411 were catastrophic. Following the invasion of Spain in September or October 409, invading tribes used extreme violence in conquering the cities of Roman Spain. A quotation from Hydatius - albeit about Spain in general - gives an idea of the last days of Ammaia: 'As the barbarians ran wild through Spain with the evil of pestilence raging as well, the tyrannical tax collector seized the wealth and goods stored in the cities and the soldiers devoured them. A famine ran riot, so dire that driven by hunger humans devoured human flesh: mothers too feasted on the bodies of their own children whom they had killed and cooked themselves... And thus with the four plagues of sword, famine, pestilence and wild beasts raging everywhere, the annunciation foretold by the Lord through his prophets was fulfilled'.

In Marvão, the once-thriving Roman town of Ammaia fell into ruin. Its 4th-century population of 6,000 people had represented about 0.1% of the Iberian population (6 million). Yet it would be described merely as 'ruins' in the 8th century CE. Why the decay? Fortified rural farmsteads and hilltop fortresses provided safe havens in times of conflict. It is likely that any Roman watchtower fortification on Marvão's rock would have been extended in this period. Ammaia's role as horse station and key link in the road network declined as east–west trade plummeted. The Visigothic capital was in Toledo, on the river Tagus: this favoured river transport of goods to-and-from Santarem and Lisbon. Ammaia's decline in this period can be contrasted with the buoyant Visigothic development of Idanha-a-Velha on the north of the Tagus.

The borders between tribes were in continuous flux, with Suevi (strongholds in Galicia and Braga) fighting the Alans and Visigoths. Five centuries of incumbent Hispano-Roman urban culture gave way to interaction with the nomadic, pastoralist lifestyles of tribes such as the Alans (dominant in much of former Lusitania after the Battle of Mérida). Roman imperial law-and-order succumbed to the looser hierarchies - based on blood and tribal allegiances - of the invaders from the north. War, slave-raids, banditry, religious intolerance, apartheid - the Visigoths applied a 'no mixing' policy for much of their rule - all led to economic decline across Iberia.

While little can be seen today in Marvão of this period, tradition states that the large herding dogs of Iberia were introduced by the Alans: (Portuguese mastiffs can be seen guarding livestock in fields around Marvão, while the bulky Alano Espãnol was used in Spanish bullfights).

Invasion: Land of the Berbers and Western Thugūr
The Muslim invasion of al-Andalus in 711 is likely to have reached the area around Marvão during the Spring campaign of Abd al-Aziz in 714 CE (when Coimbra and Santarém were also captured). The invasion would herald five centuries of Islamic rule, until Marvão was captured by the Portuguese nation-builder Afonso I of Portugal in the 1160s.

It is believed that during unstable decades from 711 to 756 in al-Andalus, power struggles between Arab and Berber factions, together with newly converted Visigoths (muwalladi), led to a division of territory: richer agricultural lands in the Guadalquivir basin fell under Arab control, and mountainous areas such as the Serra de São Mamede were generally held by Berber clansmen. Arab sources refer to the area north of the Guadiana as Bi:lad al-Barbar or Lands of the Berbers. Following the chaotic decades of invasion, by the later 8th century CE Marvão would have formed part of the Western thughūr ('march' i.e. buffer area or boundary zone) ruled by a marcher lord, or ka'id from the old Lusitanian capital of Mérida. One of three marches, this was known as the Lower March (al-Tagr al-Adna) or Distant March (al-Tagr al-Aqsa). The Lower March - the territorial division known as Xenxir - gained a reputation for the rebelliousness and reluctance of its inhabitants to comply with governance from Cordoba, with Mérida being a seething hive of discontent, revolution and tax-refuseniks. Feuds between clansmen covered a wide area across the former Lusitania province, reaching Christian lands in the north.

Ibn Marwán: Marvão's role as stronghold for the Banu Marwan wilāya


Perhaps the most important vestige of the Islamic era is the name of the village itself: Marvão is derived from the name of Ibn Marwán, a Muwallad chieftain - and reputed founder of the Spanish city of Badajoz - who rebelled against the Umayyad Emirate of Cordoba (756-929 CE). The village is mentioned as such in the 10th century by the historian Ibn Hayyan, quoting a lost original source by Isa ibn Ahmad ar-Razi, as the 'Jabal (rock) of Ammaia, known today as Ammaia of Ibn Maruán'.

Historical sources do not explain the precise role of Marvão castle itself within the 50-year statelet, or wilāya - established from 884 to 930 - controlled by Ibn Marwán, his son, grandson and great-grandson from Badajoz. While the territory of the Banu Marwan was extensive, covering much of modern-day Portugal and Extremadura, its autonomy within the Cordoban Emirate was precarious. It seems that the impenetrable fortification at Marvão acted as a deterrent to the Emirs in Córdoba. Sources quote a threat from Ibn Marwan, shortly after establishing his statelet in Badajoz 884, to 'destroy the new city' (i.e. Badajoz), and 'return to my Mountain' if Cordoban armies advance against him.

Thus Marvão - 'my mountain' - became a piece of propaganda-in-stone for Ibn Marwán. With the Marwán dynasty possessing siege-ready castles such as this, and also engaged in realpolitik with the Asturian kings in times of conflict (a key ally being Alfonso III of Asturias), there was little to be gained for the Emirate from bringing this particular rebellious marcher-state into the fold. Fortresses such as those at Marvão would now deter any spring offensives against the Banu Marwan from the Emirate in Córdoba. These offensives by the Emirate were common against another rebellious Muwalladi, notably those against Umar Ibn Hafsun, based in Bobastro near Ronda. However, the relative peace and endurance of the Banu Marwan's statelet - 46 years - testifies to the impregnability of its castles: any Emirate offensive in the São Mamede would be a bloodbath.

During its latter years, the Banu Marwan's statelet faced a major threat from reconquista-focused Christian kings from emergent states in the north. While Marvão is likely to have not been attacked in the raids of the king of León Ordoño II in 913 (which ransacked Evora to the south), it is likely to have suffered during raids during Ordoño II´s campaign to sack Mérida in 913.

Marvão under the Cordoban Caliphate


The threat of conquest from León, together with a rapid-fire series of Cordoban successes against other Muwallad rebels in the 910s-920s under Abd ar-Rahman III, is likely to have contributed to the eventual surrender of the Marwan clan to the Cordoban Caliphate in 930. Under the Caliphate (929-1031 CE), Marvão again fell under the auspices of the territorial district, or kūrah (Spanish: Cora) of Mérida, which comprised much of modern-day Portugal north of the Algarve, and comprised the Lower March (or buffer zone) bordering the Christian north.

Prior to obtaining surrender from Ibn Marvan's great-grandson, in 929 CE, the Umayyad ruler Abd-al-Rahman III had proclaimed himself Caliph of the Caliphate of Córdoba. The Umayyad Caliphate heralded a century of economic boom, maturity in governmental structures, and cultural splendour in al-Andalus, which collapsed only in the year 1008 (finally dissolving in 1031). The São Mamede mountains around Marvão are likely to have benefited during the 10th-11th century alongside the rest of al-Andalus: population increased as hamlets (aldeias) of smallholdings expanded from villas (although, in Marvão, never reaching the levels of Roman Ammaia); new shepherding pathways (karrales) criss-crossed Roman roads (calçadas), providing the dense network of mountain pathways seen today; irrigation technology and land-terracing improved, notably using gravity-flow water chutes (as-sāqiya); new crops (e.g. the doñegal fig, mulberry for silk production, citrus trees) and farming knowledge enabled more summer harvests and diversification away from the traditional vine, olive, cork oak and fig; Jewish and Christian communities were allowed considerable freedoms; some immigration occurred, with increases in the numbers of Berbers and Slavs (saqaliba, from central Europe - a notable Slav, Sabur, would be the first ruler of the taifa of Badajoz), deemed caliphate 'loyalists'. Martial traditions were kept alive by recruitment of youths to fight in summer campaigns (aceifas) against the Christian north.

Marvão under the Badajoz taifa and the Aftasids


From 1009 CE, the Cordoban Caliphate fragmented into smaller statelets, or taifas, each ruled by an emir. In 1013, Marvão fell within the new taifa of Badajoz (1013-1094), the largest taifa of al-Andalus, which stretched across Extremadura and modern-day Portugal to Lisbon and the Atlantic coast. Initially ruled by a Slav, Sabur, from the 1020s the taifa was ruled by the Aftasid dynasty, a Berber clan, with a notable emir being Muhammad ibn Abd Allah Al-Muzaffar (1045-1068).

The 11th century was to prove far less stable than the 'golden age' of Umayyad al-Andalus in the 10th century. As powerbase-fortress, Marvão is likely to have played a role in civil wars among internal factions in the Badajoz taifa during the 1020-1040s. Notably, the short-lived Taifa of Lisbon (1022-1045) was to challenge Aftasid dominance in Badajoz along the traditional land trade routes linking the Tagus through the São Mamede sierra (Santarem-Caceres). The Lisbon taifa was eventually reincorporated into the taifa of Badajoz in 1045 under Al-Muzaffar.

Such in-fighting was matched by external wars. Given its location and long line-of-sight into the Tagus basin, Marvão represented an important strategic base in the continual Muslim-Christian warring along the Lower March. In 1055, a large stretch of Moorish territory south of the Mondego river fell to the kingdom of León and Castile, led by king Ferdinand the Great (1015-1065). Coimbra would follow in 1064, and, under Ferdinand's son Alfonso VI, the vital city of Toledo in 1085. Such military successes enabled the Christian kings to exact onerous tributes, or parias, from the taifas in the south from 1055 onwards. Further, summer raiding campaigns from both Christian and Moorish forces effectively meant that the regions between the Douro river and Tagus were under continual threat - the lands south of the Douro and to the north of the Tagus became a depopulated 'buffer zone' between Christian and Moor. In 1063, a major razzia by Ferdinand sacked towns across the Seville and Badajoz taifas, and the São Mamede mountains lay en route. To make matters worse, the taifa of Badajoz was also fighting a war on its southern front: the taifa of Seville, under the poet-emirs Al-Mutamid and Al-Mutatid - was eating into territories in the Algarve. Thus throughout this period, Marvão and its neighbouring towns would have experienced the many tribulations of a martial state: the payment of taxes for wars and the paria protection money; the recruitment of its sons for battle; the billeting of any marching armies; occasional skirmishes during summer raiding campaigns; and the splitting of families during civil war.

Meanwhile, León and Castile were able to profit from the in-fighting. The Christian reconquista was moving southwards. Thus Marvão - as under Ibn Marwan - took up its deterrent role as a frontier fortress to project power beyond the court at Badajoz. Muslim domination in the region seemed on the back foot until the Battle of Sagrajas (near Badajoz, south of Marvão) in 1086. In the face of the Christian threat, the taifa emirs jointly called for assistance from Almoravid Africa under Yusuf ibn Tashfin. This crucial battle would re-establish Islamic dominance in the São Mamede for a further 70 years. The Battle of Sagrajas saw a crushing defeat of Castilian and Aragonese forces. However, for the forces of the Badajoz taifa - no doubt including fighters from Marvão - the battle of Sagrajas was a pyrrhic victory. The camp of their emir, al-Mutawakkil ibn al-Aftas, was sacked early on the morning of the battle, with many soldiers lost. The military strength of the Badajoz taifa was now much-weakened, and the Christians took advantage of this: as part of the paria tribute, the lower Tagus cities of Lisbon and Santarem were ceded in 1093 to Alfonso VI, as the Badajoz taifa attempted to defend itself from Almoravid dynasty. This effort would fail: the emir would be killed by Almoravids a year later.

The final generations of Islamic rule in Marvão: Almoravids, Almohads, reconquest
Almoravid gold dinar coin from Seville, Spain, 1116 British Museum.png coin from Seville, Spain, 1116. (British Museum).

The Almoravid gold dinar would set the standard of the Iberian maravedi.]]In the 1090s the Almoravids effectively annexed the taifas of al-Andalus: al-Andalus became a colony of the Almoravid empire administered from Marrakesh. In 1094, Lisbon was recaptured from Leon and Castile, and the taifa of Badajoz was toppled. The protection money (paria) sent to the Christian kingdoms was stopped. The Tagus valley now became the key dividing line between Christian and Moor: Marvão would become an outpost on the north-western frontier of an empire that stretched all the way to Mauritania.

The Almoravids are described as austere, battle-ready jihadists - who contrasted greatly with the luxury-accustomed poet-emirs of the taifa era. They were not merely interested in defending the realm, but made frequent incursions into Christian territories. The period has been described as one of 'an illiterate military caste controlling, but apart from, the native society'. It is likely that, alongside the rest of al-Andalus, Marvão experienced a number of key features of Almoravid rule: the introduction of illiterate Berber fighters from the Maghreb; drafting of its youth for military campaigns against the Christians (notably against Coimbra and Leiria) and Zaragoza taifa; a rise in religious fundamentalism; increased suppression of, and intolerance towards, Christian and Jewish communities, including forced conversion to Islam; religious cleansing (many Andalusi Christians were removed to Morocco).

Almoravid rule was not to last. They faced revolts at home in Morocco from a rival fundamentalist sect, the Almohads. Their tenuous hold on south west al-Andalus (the former Badajoz taifa and the Al-Garb) showed upon the death of the second Almoravid emir Al in Yusuf in 1143. An Algarve-centred rebellion by a Sufi sect, the al-Muridin - aided by Almohad arms - destabilised the region and set up a number of 'second taifa kingdoms' in Silves, Mértola and Tavira in the south. As well as being on the front line against the Christians, the São Mamede mountains are likely to have been on the northern edges of troop movements by the al-Muridin leader, Ibn Qasi and Almohad forces, against Almoravid centres of government (from 1146 to 1151). Indeed, collaboration and intrigue between Ibn Qasi, the Almohads, and a new Christian power - the fledgling Portugal, under Alfonso I of Portugal - is likely to have weakened the defensibility of the entire Tagus basin.



By the 1150s, Almohad rule was in the ascendancy over the Almoravids across al-Andalus. Yet Almohad rule in south-west Iberia would be short-lived: their embrace of holy war was matched by a new Christian fundamentalism in the north, which saw the reconquest as a crusade. The fledgling state of Portugal curried favour with the military orders - the Templars and the Hospitallers in particular - and, through its blood connections with the house of Burgundy, gained support from fortune-seeking crusaders from across the Pyrenees. During the 1140s, Alfonso I (Afonso Henriques) was able to capture Santarem (1147) and Lisbon (the latter with the help of English, Flemish and Rhinelander crusaders). Besides Alfonso I's actions in the Tagus valley, a particular destabilising factor in the Alto Alentejo and Extremadure were the exploits of the colourful 'Portuguese El Cid', Geraldo Sem Pavor (Gerald the Fearless). His private-army, 'commando-style' conquests of Almohad towns - such as Evora (1164), Cáceres (1164), Trujillo (1164), Juromenha (1165) - were so successful that they brought him into conflict with the King of León, Ferdinand II of León. While Marvão is not listed among Geraldo's many attacks on fortresses in this region, his and Alfonso I's encroachment on Leonese reconquest targets led Ferdinand II to campaign in the immediate vicinity of the São Mamede. Thus Ferdinand II conquered the vital Tagus crossing at Alcántara in 1165, and this campaign would ultimately define the western limits of Portuguese reconquest, establish the river Sever east of Marvão as a key section of the Portuguese-Spanish border.

In the midst of complex conflicts and territorial grabs between Almohads, Alfonso I, Ferdinand II and Geraldo Sem Pavor, after nearly 500 years of Islamic rule, Marvão fell to Alfonso I during military campaigns in 1166. This conquest was by no means definitive. In 1190, a major Almohad counter-offensive launched from Morocco under Abu Yusuf Ya'qub al-Mansur retook Marvão, during a campaign against the Templar stronghold of Tomar which would recapture for the Moors much of the Algarve and the Alentejo as far as the castle at Alcácer do Sal. Further, a famous victory for the Almohads in the Guadiana valley at Alarcos, in 1195, re-established Muslim control over many lands south of the Tagus (including Trujillo and Talavera). It is likely that Marvão at this point saw similar reinforcement of its fortifications, as seen at Cáceres and Trujillo. For the following thirty years, Marvão remained on the margins of a battlezone that would ultimately determine the location of today's Portuguese-Spanish border.

The Kingdom of Portugal, the plantation of settlers, Templars and Hospitallers


Following its conquest by Alfonso I in the 1160s, and its brief recapture by Almohads in the 1190s, Marvão's situation remained fragile around the start of the 13th century: it was listed among Portuguese territories only in the termo of Castelo Branco in 1214. Marvão was a recently conquered outpost, that needed to be fully integrated into Portugal, and which stood on the edge of territories conquered by an expansionist Kingdom of León. The process of Portuguesification began under the reigns of kings Sancho I and Alfonso II. Yet it was the famous Christian victory over the Almohads at Navas de Tolosa (near Jaén) in 1212 - leaving 100,000 Moors dead - that would effectively secure this area of south-western Iberia, and establish a lasting peace. The São Mamede mountains and Guadiana valleys now became a bridgehead from which the reconquista could make strong inroads into Almohad territory in the Southern Alentejo, Algarve, Southern Extremadura and north-west Andalusia.

Marvão's role as fortress now became more important not as a Christian or Moorish outpost-against-the-infidel, but as a territorial marker for the young - and by no means militarily strong - state of Portugal against the competing Christian Kingdom of León. In 1226, Marvão was among the earliest towns on the eastern border to receive from Sancho II of Portugal its foral (i.e. royal charter, allowing the town to regulate its administration, borders and privileges). Another aspect of 13th century statecraft that would bolster the area's 'Portugalidade' (Portuguese identity) would be the settlement of planted Christian colonists from the north (Galicia, the Minho), southern France and Flanders in territories around Marvão. This was done with royal approval, and with the intermediation of the Templars and Hospitallers. The resettlement of barren areas depopulated by centuries of warfare and bloodshed - or simply abandoned by fleeing Berber refugees - was vital to sustain the new Portuguese kingdom. Many of these settlers were Galicians, and the name of the hamlet of Galegos in Marvão is likely to refer to its 13th–14th century settlers. Other nearby settlements took names from southern France: in the nearby Templar-controlled village of Nisa (Nice), we find hamlets named Tolosa (Toulouse), Montalvão (Montauban) and Arez (Arles) to denote the origins of their settlers.

Perhaps the most important development for Marvão at this time was the donation of borderlands to the military orders. The Templars, strong allies of Alfonso I, had during the 12th century been given lands north of the Tagus, including their headquarters at Tomar, and Castelo Branco, and given broad responsibility to secure the river passage on the river. In 1199, Sancho I of Portugal awarded lands to the north of Marvão (the Herdade da Açafa). These extended across the present-day districts of Castelo de Vide and Nisa and into territories near Valencia de Alcántara that now lie in Spain. In 1232, Sancho II of Portugal donated further extensive domains south of the Tagus around Marvão and Portalegre to the Knights Hospitaller, along with the duty to fortify the frontier and help in its repopulation. The Hospitallers would dominate the administration of the region for two centuries, moving their Portuguese headquarters from Leça in Northern Portugal to nearby Crato in 1340. Much of the architecture to be admired today in Marvão can be attributed to the guiding hand of the Hospitallers in extending the castle and village in the 13th-15th centuries. Hospitaller (Maltese) crosses can be seen on houses throughout Marvão's walled village, including the door of the church that is the Municipal Museum.

Marvão´s castle: an archetype of medieval castle-building


As with other 11th-13th-century castles, the early medieval improvements and development of Marvão castle reflect the innovations brought back by crusading orders from the near east (notably the highly influential Hospitaller castle in Syria, the Krak des Chevaliers). The medieval castle seen in Marvão today mostly post-dates the year 1299, and features numerous characteristic features of a crusader-era castle: a tall central keep with raised entrance on the first floor; a series of lower, outlying turrets (some semi-circular); high-placed arrow-slits; open spaces to aid the sheltering and assembly of villagers and troops; a well, and huge rain-collecting cistern to supply water to both keep and the wider castle in the event of siege; bent entrances (both on the village and castle gates) to slow down invaders in the event of breached gates; a series of narrow killing zones (notably, in the triple gate on the village-side of the castle); extensive crenellated battlements and curtain walls that enhanced the natural defences provided by the escarpments of Marvão's rock.

Dom Dinis (King Denis) and Afonso IV
The 13th century saw considerable instability across western Iberia, intensifying the need for a clearly demarcated, strongly defended border. Under the King Denis (1261-1325), Marvão benefited from the king's focus on bolstering Portugal's border with the neighbouring Kingdom of Castile. King Denis's border pact with Ferdinand IV of Castile (1297) was followed by considerable investment in a chain of Portuguese castles along the border, with Marvão castle being considerably extended from 1299 onwards using Hospitaller expertise. On the Castilian side of the border, castles were likewise reinforced at nearby Valencia de Alcántara and Mayorga, the Order of Alcántara being a Castilian counterpart to the Hospitaller's role in Portugal.

A civil war in the Kingdom of Castile from 1296 to 1301 - which saw the Kingdom of León briefly break away from Castile - brought risk of contagion into Portugal's eastern frontier. Another major conflict occurred from 1319 to 1326: King Denis's bastard son, Afonso Sanches, lord of nearby Alburquerque was made mayordomo (akin to prime minister) of Portugal, and was nominated preferred heir, by King Denis. Sanches's castle in Alburquerque was clearly visible from Marvão, and his wife's family held nearby lands in La Codosera, making the 'raia' area a power base for Sanches. A civil war (1319-1326) where Denis's legitimate son, the future Afonso IV, rebelled against his father Kind Denis, meant that Marvão and other fortresses on the border would see action ahead of the Battle of Alvalade.

18th Century
During the Fantastic War, an attempted Spanish and French invasion of Portugal in late 1762, a Spanish force of 4–5,000 attempted to take Marvão with a frontal attack. An Anglo Portuguese garrison under Captain Thomas Browne defeated the Spaniards who fled with heavy loss, contributing to Spain asking for a truce in November.

Demographics
Marvão's population is subject to a combination of ageing, declining birthrate and rural exodus. Since the 1990s, the municipality has been losing just under one inhabitant per week.
