The capture of the city of Lisbon from the Almoravid Muslims in October 1147 after a months-long siege was a by-product of the Second Crusade to the Holy Land and the only major Christian victory of that campaign. It proved to be a pivotal turning point in the history of Portugal as it mutated from being a subordinate vassal of León into an independent Christian kingdom.

When he announced the start of the Second Crusade, Pope Eugene III, echoing an earlier mandate from Pope Urban II, stated that Christians in the Iberian Peninsula could crusade against the Muslims there rather than travel to the Holy Land. On June 16, 1147, 164 ships carrying 6,000 English and Scottish, 5,000 German, and 2,000 Flemish crusaders put in to Porto to escape a storm. Afonso Henriques, self-proclaimed King of Portugal, asked them to join his own personal crusade to capture Lisbon from the Muslims. He offered them the moveable goods of the Muslims in the city and any ransoms that could be extracted.

The crusaders agreed and, on July 1, 1147, laid siege to Lisbon, while Afonso and his army occupied the surrounding countryside. The crusaders built mangonels and other devices and bombarded the city. The Muslims launched a sortie and burned the siege engines. Thereafter the fighting almost stopped as the crusaders settled down to a blockade, finally broken when the crusaders captured a section of the city wall. On October 21, the garrison agreed to surrender on condition they were allowed to march out freely. The gates of Lisbon were opened four days later, which brought the siege to an end on October 25, 1147.

Although the terms of surrender included safe passage of Lisbon’s inhabitants after they relinquished a portion of their wealth, the foreign crusaders sacked the city and, according to a contemporary chronicle, took an unknown number of lives before being called off. Many English crusaders opted to stay in Portugal—one of them became Bishop of Lisbon—while the Germans and Flemings continued to the Holy Land. Lisbon became capital of Portugal, which won papal recognition as an independent kingdom.

The siege of Lisbon is considered the only true victory of the Second Crusade, which was otherwise a humiliating failure.

Losses: Crusader, minimal of 15,000; Muslim, few of 7,000-strong garrison; civilian, unknown.

Reconquista, in medieval Spain and Portugal, a series of campaigns by Christian states to recapture territory from the Muslims (Moors), who had occupied most of the Iberian Peninsula in the early 8th century.

Though the beginning of the Reconquista is traditionally dated to about 718, when the Christian Asturians opposed the Moors at the Battle of Covadonga, the impulse toward reconquest was expressed only sporadically through the first three centuries of Muslim hegemony. After a failed invasion of Muslim Spain in 778, in 801 Charlemagne captured Barcelona and eventually established Frankish control over the Spanish March, the region between the Pyrenees and the Ebro River. Asturian kings, presenting themselves as the heirs to the Visigothic monarchy that had ruled Spain prior to the Muslim conquest, capitalized on dissension within the Moorish ranks and expanded their holdings in the late 9th century. The Reconquest might have taken root at that earlier date had it not been for a resurgence in the power of the Córdoban caliphate and a break between the Christian kingdoms of Castile and León in the 10th century.

In the meantime, the Christian and Islamic peoples of Spain had become tightly associated with each other culturally and economically, to the extent that consequences of the crusading spirit that manifested in the 11th century were often scarcely less harmful to the Christian conquerors than to the conquered Moors. At that time, Moorish unity broke down, and the Christian lands of northern Spain were briefly united under Sancho III Garcés (Sancho the Great), who greatly expanded the holdings of Navarre. Sancho created the kingdom of Aragon in 1035, and his successors there pursued the Christian reclamation of the peninsula in earnest. Alfonso I of Aragon captured the former Moorish capital of Zaragoza in 1118. In 1179 Alfonso II of Aragon and Alfonso VIII of Castile concluded the Pact of Cazorla, an agreement whereby the task of reconquering the Moorish kingdom of Valencia was reserved to the Aragonese crown. In exchange Aragon relinquished all claims to other Moorish-held territory in the peninsula.

After suffering a crushing defeat at the Battle of Alarcos (July 18, 1195) at the hands of the Almohad caliph Abū Yūsuf Yaʿqūb al-Manṣūr, Alfonso VIII appealed to other Christian leaders, and in 1212 he won the support of Pope Innocent III, who declared a Crusade against the Almohads. Supported by the armies of Aragon, Navarre, and Portugal, Castilian forces routed the Almohad emir of Morocco, Muḥammad al-Nāṣir, at Las Navas de Tolosa (July 16, 1212) and so removed the last serious Islamic threat to Christian hegemony in Spain. The way was now open to the conquest of Andalusia.

The last king of León, Alfonso IX, was succeeded upon his death in 1230 by his son, Ferdinand III, who was already king of Castile. Castile and León were thus reunited, and the new sovereign at once embarked on a great series of campaigns to subdue Andalusia. Those began with the capture of Córdoba (1236) and culminated in the surrender of Sevilla (1248). Influenced by the crusading zeal instilled into the Spanish church by the Cluniac and Cistercian orders, Ferdinand at first expelled the Moorish inhabitants of the Andalusian cities en masse but was later forced to modify his policy by the collapse of the Andalusian economy that inevitably ensued. He also assented, chiefly for financial reasons, to the establishment of the new Moorish kingdom of Granada under Castilian suzerainty. The Granadine Moors were forced to pay to Castile a sizable annual tribute, but Moorish culture experienced something of a rebirth in Christian Spain. In Toledo, a Castilian city already famous throughout Europe as a crossroads of Christian, Arab, and Jewish thought, Alfonso X established the Escuela de Traductores (School of Translators), an institution that made Arabic works available to the Christian West.

During the same period, James I of Aragon completed Aragon’s part in the Reconquest. After occupying the Balearics (1235), he captured Valencia (1238). Unlike Ferdinand, James carefully worked to preserve the agricultural economy of the Moors and so established the final peninsular frontiers of Aragon. In Portugal, Afonso III captured Faro (1249), the last Moorish stronghold in the Algarve. By the end of the 13th century, the Reconquest was, for all practical purposes, brought to an end. The last significant Muslim incursion into Christian Iberia culminated with the Battle of Río Salado (October 30, 1340), where Portuguese and Castilian forces administered a crushing defeat to the armies of Marīnid sultan Abū al-Ḥasan ʿAlī.

The kingdoms of Aragon, Castile, and Portugal spent the next century consolidating their holdings, until the marriage of Ferdinand II of Aragon and Isabella I of Castile in 1469 united the Spanish crown. The Catholic Monarchs, as Ferdinand and Isabella came to be known, completed the conquest of Granada in 1492. Many historians believe that the crusading spirit of the Reconquista was preserved in the subsequent Spanish emphasis on religious uniformity, evidenced by the strong influence of the Inquisition and the expulsion of people of Moorish and Jewish descent.
