On 13 March 1979, whilst Gairy was out of the country, the NJM launched a bloodless coup which removed Gairy, suspended the constitution, and established a People's Revolutionary Government (PRG), headed by Maurice Bishop who declared himself Prime Minister. His Marxist–Leninist government established close ties with Cuba, Nicaragua, and other communist bloc countries. All political parties except for the New Jewel Movement were banned and no elections were held during the four years of PRG rule.
