Why do different Christian denominations care for separate areas of the Church of the Holy Sepulchre?

Different Christian denominations control specific areas of the Church of the Holy Sepulchre due to long-standing competing claims of ownership over the site, which is traditionally venerated as the location of Jesus’ crucifixion and burial.12

To manage these competing interests and prevent conflict between the various clerics, the administration of the church is governed by a rule known as the "status quo," which was promulgated by the Ottoman sultan in 1852. Under this arrangement, major groups—including the Greek Orthodox Church, the Roman Catholic Church, and the Armenian Apostolic Church, among others—maintain control over specific sections and conduct services regularly.312

Furthermore, to ensure neutrality and prevent disputes between the denominations, the responsibility for holding the church's only key has been entrusted to a Muslim family since the Ayyubid period (1187–1229).2
