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, 100 miles (160 km) north of Venezuela. Codenamed Operation Urgent Fury by the U.S. military, it resulted in military occupation within a few days.^[9] 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 nearly bloodless 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.^[10] 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. Bishop made his way to the army headquarters at Fort Rupert (known today as Fort George). After he arrived, a military force was dispatched from Fort Frederick to Fort Rupert. Bishop and seven others, including cabinet ministers, were captured. Then a four-man People's Revolutionary Army firing squad executed Bishop, three members of his Cabinet and four others by machine-gunning them.

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).^[11] President Reagan stated that he felt compelled to act due to "concerns over the 600 U.S. medical students on the island" and fears of a repeat of the Iran hostage crisis, which ended less than three years earlier. According to the future United States Secretary of State Lawrence Eagleburger, who was serving as Reagan's Under Secretary of State for Political Affairs at the time of the invasion, the prime motivation for the US intervention was to "get rid" of the coup leader Hudson Austin, and the students were the pretext.^[12] While the invasion followed the execution of Maurice Bishop, his party members intending to gain power still maintained his communist ideologies. President Reagan expressed that he viewed this, alongside the party's growing connection to Fidel Castro, as a threat to democracy.^[13]

The invading force consisted of the 1st and 2nd battalions of the US Army's 75th Ranger Regiment, the 82nd Airborne Division, and elements of the former Rapid Deployment Force, U.S. Marines, US Army Delta Force, Navy SEALs, and ancillary forces, totaling 7,600 troops, together with Jamaican forces and troops of the Regional Security System (RSS).^[14] The force defeated Grenadian resistance after a low-altitude airborne assault by the Rangers and 82nd Airborne on Point Salines Airport, at the south end of the island, and a Marine helicopter and amphibious landing on the north end, at Pearls Airport. Austin's military government was deposed and replaced, with Scoon as Governor-General, by an interim advisory council until the 1984 elections.

The invasion was criticized by many countries. British Prime Minister Margaret Thatcher privately disapproved of the mission, in part because she was not consulted in advance and was given very short notice of the military operation, but she supported it in the press.^[15] The United Nations General Assembly condemned it as "a flagrant violation of international law" on 2 November 1983, by a vote of 108 to 9.^[16]

The date of the invasion is now a national holiday in Grenada, called Thanksgiving Day, commemorating the freeing of several political prisoners who were subsequently elected to office. A truth and reconciliation commission was launched in 2000 to re-examine some of the controversies of the era; in particular, the Commission made an unsuccessful attempt to find Bishop's body, which had been disposed of at Austin's order and never found.

The invasion highlighted issues with communication and coordination between the different branches of the American military when operating together as a joint force, triggering post-action investigations resulting in sweeping operational changes in the form of the Goldwater-Nichols Act and other reorganizations.^[17]
