The New Jewel Movement, headed by Maurice Bishop, ousts the Prime Minister of Grenada, Eric Gairy, in a coup d'état.

The New Joint Endeavor for Welfare, Education, and Liberation, or New JEWEL Movement (NJM), was a Marxist–Leninist vanguard party in the Caribbean island nation of Grenada that was led by Maurice Bishop.

Maurice Rupert Bishop was a Grenadian revolutionary and the leader of the New Jewel Movement (NJM) – a Marxist–Leninist party that sought to prioritise socio-economic development, education and black liberation. The NJM came to power during the 13 March 1979 revolution which removed Prime Minister Eric Gairy from office. Bishop headed the People's Revolutionary Government of Grenada (PRG) from 1979 to 1983. In October 1983, he was deposed as Prime Minister and executed during a coup engineered internally by Deputy Prime Minister Bernard Coard with decisive support from the United States. This quickly led to the demise of the PRG.

This is a list of heads of government of Grenada, from the establishment of the office of the chief minister in 1960 to the present day.

Sir Eric Matthew Gairy PC was the first Prime Minister of Grenada, serving from his country's independence in 1974 until his overthrow in a coup by Maurice Bishop in 1979. Gairy also served as head of government in pre-independence Grenada as Chief Minister from 1961 to 1962 and as Premier from 1967 to 1974.

A coup d'état, or simply a coup, is typically an illegal and overt attempt by a military organization or other government elites to unseat an incumbent leadership. A self-coup is said to take place when a leader, having come to power through legal means, tries to stay in power through illegal means.
