This Ugandan group is now infamous for orchestrating the mass murder of its devoted following. They believed a prophecy that said the world would end on Jan. 1, 2000, but when the new year came and went without an apocalypse, things started to go downhill for the Movement. Many members had sold their belongings in anticipation of their demise and began turning on church leaders. Conveniently, God came through with a new promised end of days: March 17, 2000. On that date, congregation members were invited to a party at their Kanungu location. The doors and windows were sealed shut and an explosion was set off, killing the unsuspecting worshippers inside. Authorities later found bodies buried at other Movement locations — many of which showed signs of poisoning or stabbing that predated the explosion. Two of the Movement leaders, Joseph Kibweteere and Credonia Mwerinde, are thought to still be alive and police still have warrants out for their arrest. While this gruesome incident hasn't garnered the myth-status of others, the death toll remains mind-boggling: More than 700 people lost their lives to the Movement on that one day.
