Anti-government protesters march to mark the 64th anniversary of Thai King Bhumibol Adulyadej's coronation in Bangkok on May 5, 2014
Thailand's Constitutional Court dismissed Prime Minister Yingluck Shinawatra from office for abuse of power on Wednesday, a ruling that threatens to unleash a new wave of unrest.
This is a timeline of the political crisis since demonstrations aimed at toppling her government began more than six months ago:

November 1: The lower house of parliament, which is dominated by the ruling party, votes in favour of the bill.
November 11: Amid growing outrage on the streets, the upper house overwhelmingly rejects the legislation.
