The 1971 Janatha Vimukthi Peramuna (JVP) insurrection (also known as the 1971 Revolt) was the first of two unsuccessful armed revolts conducted by the communist Janatha Vimukthi Peramuna (JVP) against the socialist United Front Government of Sri Lanka (then Ceylon) under Prime Minister Sirimavo Bandaranaike. The revolt began on 5 April 1971, and lasted until June of that year. The insurgents held towns and rural areas for several weeks, until the regions were recaptured by the armed forces, following strong support from friendly nations that sent men and material. Although this first attempt to seize power was quickly crushed by force, in 1987 the JVP launched a low intensity insurgency in the island's southern, central and western regions that lasted several years.
