Black May (Thai: พฤษภาทมิฬ; RTGS: Phruetsapha Thamin), also known as "Bloody May", was a series of mass protests and subsequent crackdowns by security forces and police in Bangkok in May 1992. A rally of over 200,000 people led by Chamlong Srimuang was held on 17 May, caused by the extending of the military regime of Suchinda Kraprayoon, the 1991 Thai coup d'état leader. An estimated 52 to 100 protesters were killed, 696 were injured, and 175 had "disappeared" afterwards. King Bhumibol Adulyadej summoned both Chamlong and Suchinda on 20 May, and the Suchinda regime later received a sweeping amnesty along with other law reforms, signed by Bhumibol.
