What role did salahuddin ayubi played in the conquest of Jerusalem?

Salahuddin Ayubi, also known as Saladin, played a pivotal role in the conquest of Jerusalem during the Crusades. After years of conflict with the Crusaders, he united Muslim forces and launched a campaign to reclaim the city, culminating in the decisive Battle of Hattin in 1187. His victory there enabled him to retake Jerusalem later that year, ending nearly 90 years of Crusader rule. Saladin's leadership and military strategy not only restored Muslim control over the city but also earned him respect for his chivalry and treatment of enemies.
