Which event failed to recapture Jerusalem during the Third Crusade?

The event that failed to recapture Jerusalem during the Third Crusade pertains to the actions of Richard the Lionheart and Frederick Barbarossa. The Third Crusade took place from 1189 to 1192 and was launched in response to Saladin’s capture of Jerusalem in 1187. While Richard the Lionheart led significant military campaigns, including victories at battles such as Acre and Jaffa, and worked alongside Frederick Barbarossa of the Holy Roman Empire, the crusade did not manage to retake Jerusalem.

Despite their combined efforts, the logistical difficulties and the strong defenses established by Saladin prevented them from achieving their ultimate goal of recapturing the city. Richard and Saladin did arrive at a point where negotiations took place, which ultimately led to a treaty allowing Christian pilgrims access to Jerusalem, but it did not result in the capture of the city itself. Thus, their endeavor, despite some military successes, failed to achieve the primary objective of recapturing Jerusalem.

The other events listed do not relate to the Third Crusade or its objectives—such as the signing of the Treaty of Versailles, which occurred centuries later, the defeat of the Spanish Armada in 1588, or the Russian Revolution in the early 20th century. Each
