After the general election on 22 March 1992, five parties (Rassadorn, Justice Unity, Social Action, Thai Citizen, Chart Thai) designated Suchinda as the prime minister. His appointment as Prime Minister on 7 April 1992 resulted in large protests, culminating in a general curfew and military deployment in Bangkok. In the event known as Black May, hundreds of people are believed to have died when soldiers opened fire on unarmed students and demonstrators during the protests. Further escalation was avoided by the intervention of King Bhumibol.
