In Sri Lanka, Janatha Vimukthi Peramuna launches a revolt against the United Front government of Sirimavo Bandaranaike.

Janatha Vimukthi Peramuna (Sinhala: ජනතා විමුක්ති පෙරමුණ, Tamil: மக்கள் விடுதலை முன்னணி, lit. 'People's Liberation Front'; JVP) is a Marxist–Leninist communist party and a former militant organization in Sri Lanka. The movement was involved in two armed uprisings against the government of Sri Lanka: once in 1971 (SLFP), and another in 1987–89 (UNP). The motive for both uprisings was to establish a socialist state.The JVP was initially a small organisation that became a well-organised party that could influence mainstream politics. Its members campaigned openly for the left-wing coalition government, United Front. Following their disillusion with the coalition, they started an insurrection against the Dominion of Ceylon in early 1971, which intensified following the ban on the party. The military arm the Red Guard captured over 76 police strongholds throughout the island of Ceylon.The JVP entered democratic politics in 1977 when President J.R. Jayewardene released the JVP leader, Rohana Wijeweera, from prison. After the United Front coalition government collapsed, Wijeweera contested the presidential elections in 1982 and obtained 4.16 percent of the votes cast. Before the elections, he had been convicted through the Criminal Justice Commission (CJC) for conspiring to overthrow the state violently. The JVP launched a more organized insurrection for the second time in 1987 after the Indo-Sri Lanka accord was signed.

Following Operation Combine and Wijeweera's death, the JVP returned to elections as the National Salvation Front. The surviving JVP members campaigned in the 1994 elections, but eventually withdrew and supported the nationalist opposition party, Sri Lanka Freedom Party. In 2004, it joined the government as a part of the United People's Freedom Alliance and supported the government in its war against the Liberation Tigers of Tamil Eelam (LTTE), but subsequently left the coalition government.

Later, it contested under its own national coalition and has since been a third party in overall Sri Lankan politics.
