The term "Jerusalem Kings" typically refers to the rulers of the ancient city of Jerusalem, particularly during the periods of the United Monarchy and the Kingdom of Judah. Notable kings include David, who established Jerusalem as the capital, and his son Solomon, known for building the First Temple. These kings played significant roles in the religious and political history of the region. In addition to the biblical kings, the title can also refer to rulers during the Crusades, such as Baldwin IV, who was king of Jerusalem in the 12th century. These leaders faced challenges from both internal factions and external threats, shaping the city's complex history.
