James Warren Jones (May 13, 1931 – November 18, 1978) was an American cult leader who founded and led the Peoples Temple between 1955 and 1978. Jones and the members of his inner circle planned and orchestrated a mass murder–suicide that resulted in the deaths of over 900 people which he described as "revolutionary suicide", a term coined by Huey P. Newton, in his remote jungle commune at Jonestown, Guyana on November 18, 1978, including the assassination of U.S. congressman Leo Ryan. Jonestown had a defining influence on society's perception of cults. Wikipedia
