What did the crusaders do when they conquered Jerusalem?

When the Crusaders conquered Jerusalem in 1099 during the First Crusade, they engaged in a brutal assault on the city, resulting in widespread violence and the massacre of many inhabitants, including Muslims and Jews. After capturing Jerusalem, they established a Latin Kingdom and reclaimed the site of the Holy Sepulchre, which they considered a significant religious victory. The conquest marked a pivotal moment in the Crusades, solidifying Christian control over the city for nearly a century.
