The Invasion of Grenada, codenamed Operation Urgent Fury, was a 1983 U.S.-led invasion of Grenada, a Caribbean island nation of just over 100,000 population located 100 miles (160 km) north of Venezuela, triggered by a military coup which ousted a brief revolutionary government. The successful invasion led to a change of government but was controversial due to charges of American imperialism, Cold War politics, the involvement of Cuba, the unstable state of the Grenadian government, and Grenada's status as a Commonwealth realm.
Grenada gained independence from the United Kingdom in 1974, but a 1979 revolution by the Marxist-Leninist New Jewel Movement suspended the constitution. After a 1983 internal power struggle ended with the deposition and execution of Grenadian Prime Minister Maurice Bishop, the invasion began on October 25, 1983. A combined force of troops from the United States (nearly 10,000 troops), Jamaica and members of the Regional Security System (RSS) (approximately 300 troops) defeated Grenadian resistance and the military government of Hudson Austin was deposed.
The invasion was criticized by the United Kingdom, Canada and the United Nations General Assembly, which condemned it as "a flagrant violation of international law". It enjoyed broad public support in the United States as well as widespread support by the people of Grenada, who viewed the post-coup regime as illegitimate. October 25 is a national holiday in Grenada, called Thanksgiving Day, to commemorate this event. Additionally, on 29 May 2009, the Point Salines International Airport was officially renamed in honour of the slain pre-coup leader Maurice Bishop by the Government of Grenada.
