Jonestown massacre
18 November 1978
The Peoples Temple Agricultural Project, better known by its informal name Jonestown, was a remote commune in Guyana established by the Peoples Temple, an American religious organization led by Jim Jones. On November 18, 1978, 918 people died in a coordinated mass murder-suicide across three locations: the Jonestown compound, a nearby airstrip in Port Kaituma, and the group's headquarters in Georgetown, making "Jonestown" internationally infamous.
