The Sri Lanka Riots:, targeting the minority Sri Lankan Tamils, begin, less than a month after the United National Party came to power. Over 300 Tamils are killed.

The 1977 anti-Tamil pogrom in Sri Lanka followed the 1977 general elections in Sri Lanka where the Sri Lankan Tamil nationalistic Tamil United Liberation Front won a plurality of minority Sri Lankan Tamil votes in which it stood for secession. An official estimate put the death toll at 125. The Tamil Refugees Rehabilitation Organization estimated that around 300 Tamils were killed by Sinhalese mobs. Human rights groups, such as the UTHR-J, accused the newly elected UNP run Sri Lankan government of orchestrating the violence. Though the majority of victims were Tamils, Sinhalese in Tamil majority areas were also affected by violence committed by Tamil mobs.
