Which of the following was the site of the only victory achieved by the Crusaders in the Second Crusade? A. Ephesus B. Lisbon C. Constantinople D. Damascus

To answer the question regarding the site of the only victory achieved by the Crusaders in the Second Crusade, we must analyze the context of the Second Crusade and the events that occurred during it.

1. Context of the Second Crusade: The Second Crusade (1147–1150) was launched in response to the fall of the County of Edessa in 1144 to Zengi, the Turkish ruler of Mosul. It was notable for a series of military campaigns initiated by European leaders.

2. Victory Analysis: The Crusaders faced significant challenges during this campaign, particularly in their attempts to capture cities that were crucial to their objectives. Notably, while they encountered defeats at key locations, they achieved victory at Lisbon.

3. Historical Significance: The Siege of Lisbon in 1147 was a critical success for the Crusaders. After laying siege to the city, they captured it with the help of local Christian forces. This victory was instrumental in establishing a foothold in the Iberian Peninsula during the Reconquista, even though it was not directly linked to the traditional goals of the Crusade itself.

Considering all of this information, the correct answer is B. Lisbon. This city was indeed the site of the only significant victory that the Crusaders achieved during the Second Crusade.
