During World War I, the Hashemites requested help and support from the British Empire via its administration in Cairo to fight against the Ottomans. The sudden revolt led by the Hashemite family, while not be able to secure total support from other Arab tribes, played an instrumental role on the collapse of Ottoman rule in Jordan. However, the main goal of Hashemite-led revolt - a unitary and independent Arab state - was not honored by London and its French ally. Eventually Britain placed Sharif Abdullah as ruler of the Emirate of Transjordan, hoping to reduce tensions.
