Why were the christians and muslims fighting over the city jerusalem

Jerusalem is one of the holiest places in the world. It´s a holy place for the three monotheistic religions Judaism, Christianity and Islam. The wars over the control of Jerusalem in the past - the crusades - were motivated by the desire of the Roman Catholic Church and some European monarchs to establish Christian dominion of the holy city. But it was also a holy place for Muslims. Jerusalem is where Jesus´ passion, death and resurrection took place. For Muslims, Jerusalem is the site where profet Muhammad ascended to Heaven.
