The siege of Lisbon, from 1 July to 25 October 1147, was the military action that brought the city of Lisbon under definitive Portuguese control and expelled its Moorish overlords. The siege of Lisbon was one of the few Christian victories of the Second Crusade. It is seen as a pivotal battle of the wider Reconquista. On October 1147, after a four month siege, the Moorish rulers agreed to surrender, primarily due to hunger within the city. Most of the crusaders settled in the newly captured city, but some of them set sail and continued to the Holy Land. Some of them, who had departed earlier, helped capture Santarém earlier in the same Year. Later they also helped to conquer Sintra, Almada, Palmela and Setúbal, and they were allowed to stay in the conquered lands, where they settled down and had offspring.
