Who involved the second crusade and the result?

The Second Crusade (1147–1149) involved key figures such as King Louis VII of France and Emperor Conrad III of Germany, who led their armies to the Holy Land in response to the fall of the County of Edessa. The Crusade aimed to recapture Edessa and reinforce Christian control in the region. Ultimately, the campaign was largely unsuccessful, with both leaders facing significant challenges, including internal strife and military defeats, culminating in the failure to achieve their objectives and a retreat from the Holy Land.
