Hashemite custodianship of Jerusalem holy sites
Hashemite custodianship refers to the Jordanian royal family's role in tending Muslim and Christian holy sites in the city of Jerusalem. The legacy traces back to 1924 when the Supreme Muslim Council, the highest Muslim body in charge of Muslim community affairs in Mandatory Palestine, chose Hussein bin Ali (Sharif of Mecca) as custodian of Al-Aqsa.
