The United States invasion of Grenada began at dawn on 25 October 1983. The United States and a coalition of six Caribbean nations invaded the island nation of Grenada, north of Venezuela. Codenamed Operation Urgent Fury by the U.S. military, it resulted in military occupation within a few days. It was triggered by the strife within the People's Revolutionary Government, which resulted in the house arrest and execution of the previous leader and second Prime Minister of Grenada, Maurice Bishop, and the establishment of the Revolutionary Military Council, with Hudson Austin as chairman. The invasion resulted in the appointment of an interim government, followed by elections in 1984.
Grenada had gained independence from the United Kingdom in 1974. The Communist New Jewel Movement seized power in a coup in 1979 under Maurice Bishop suspending the constitution and detaining several political prisoners. In September 1983, an internal power struggle began over Bishop's leadership performance. Bishop was pressured at a party meeting to share power with Deputy Prime Minister Bernard Coard. Bishop initially agreed, but later balked. He was put under house arrest by his own party's Central Committee until he relented. When his secret detention became widely known, Bishop was freed by an aroused crowd of his supporters. A confrontation then ensued at military headquarters between Grenadian soldiers loyal to Coard and civilians supporting Bishop. Shooting started under still-disputed circumstances. At least 19 soldiers and civilians were killed on 19 October 1983, including Bishop, his partner Jacqueline Creft, two other Cabinet ministers, and two union leaders.
The Reagan administration mounted a US military intervention following receipt of a formal appeal for help from the Organisation of Eastern Caribbean States, which had received a covert appeal for assistance from the Governor-General of Grenada, Paul Scoon (though he put off signing the formal letter of invitation until 26 October).
