In the early 1980s, members of the Rajneesh movement moved in and effectively took over the government of the city by outnumbering the original residents with new voter registrations. On September 18, 1984, a vote was held and the city was renamed to "Rajneesh, Oregon". By 1985, after several of the Rajneesh movement leaders were discovered to have been involved in criminal behavior (including a mass food poisoning attack and an aborted plot to assassinate a U.S. Attorney), their guru left the country as part of a negotiated settlement of federal immigration fraud charges, and the Rajneesh commune collapsed. On November 6, 1985, the city voted to rename itself back to Antelope.
