Answer 2

Answer:

The Second Crusade, besides Edessa, had additional objectives in Iberia and the Baltic, and both campaigns were backed by the Pope. The crusaders who were to sail to the east were perhaps used in Iberia because they had to delay their departure in order for the land armies to make their slow progress to the Levant. The sea route was much quicker and so it was advantageous to put them to good use in the meantime. A fleet of some 160-200 Genoese ships packed with crusaders sailed for Lisbon to assist King Alfonso Henriques of Portugal (r. 1139-1185 CE) capture that city from the Muslims. On arrival, a textbook siege began on 28 June 1147 CE and was ultimately successful, the city falling on 24 October 1147 CE. Some crusaders successfully continued the war against the Muslims in Iberia, the reconquista, as it was known, notably capturing Almeria in northern Spain (17 October 1147 CE) guided by King Alfonso VII of León and Castille (r. 1126-1157 CE) and Tortosa in eastern Spain (30 December 1148 CE). An attack on Jaén in southern Spain, though, was a failure.
