The Cinema Rex fire occurred on 19 August 1978 when the Cinema Rex in Abadan, Iran, was set ablaze, killing between 377 and 470 people. The event started when four individuals, who were militants motivated by Islamic extremism, doused the building with airplane fuel before setting it alight. The attack was responsible in part for triggering the Iranian Revolution of 1979, which saw the overthrow of the ruling dynasty under the Iranian monarch and a related outbreak of mass violence.
