In early April 1941, during World War II, Rashid Ali al-Gaylani and members of the anti-British "Golden Square" launched a "coup d'état" against the current government. Prime Minister Taha al-Hashimi resigned and Rashid Ali al-Gaylani took his place as Prime Minister. Rashid Ali also proclaimed himself chief of a "National Defence Government." He did not overthrow the monarchy, but installed a more compliant Regent. He also attempted to restrict the rights of the British which were granted them under the 1930 treaty.
