The 2010 Thai political protests were a series of political protests that were organised by the United Front for Democracy Against Dictatorship (UDD) in Bangkok, Thailand from 12 March–19 May 2010 against the Democrat Party-led government. The UDD called for Prime Minister Abhisit Vejjajiva to dissolve parliament and hold elections earlier than the end of term elections scheduled in 2012. The UDD demanded that the government stand down, but negotiations to set an election date failed. The protests escalated into prolonged violent confrontations between the protesters and the military, and attempts to negotiate a ceasefire failed. More than 80 civilians and six soldiers were killed, and more than 2,100 injured by the time the military violently put down the protest on 19 May.

The Red Shirts are a political movement in Thailand, formed following the 2006 coup d'état which deposed then-Prime Minister Thaksin Shinawatra. Originally synonymous with the United Front for Democracy Against Dictatorship (UDD), a group formed to protest the coup and resulting military government, the movement subsequently expanded to include various groups with diverse political priorities. Its members range from left-wing and/or liberal activists and academics to the large number of Thaksin's rural and working-class supporters. The movement emerged as the result of socio­economic changes in Northeast Thailand in the 1990s and 2000s, including a growing middle class, rising aspirations, and an increasing awareness of the extreme inequality and of the fundamentally weak democracy in Thailand, typified by Thailand's primate city problem. Red Shirts group dynamics center on frustrated economic and political aspirations to improve democracy and overcome inequality, which contributed to the 2009 Thai political unrest and the 2010 Thai political protests, as well as shared suffering at the hand of the ruling class hegemony. As with other minorities, the Red Shirts have been dehumanized and demonized, with insults such as "Red Buffalo", since reclaimed by some of its targets. Their claims for transitional justice following the 2010 Thai military crackdown have been subverted by the Thai state.
