Leland Jensen

Leland Jensen (22 August 1914–6 August 1996) was the founder of a Bahá'í sect called the Bahá'ís Under the Provisions of the Covenant (BUPC). Jensen initially supported the claim of Mason Remey to be the successor to Shoghi Effendi in 1960, resulting in his excommunication from the mainstream Bahá'í community. Jensen further believed that he was chosen by God to re-establish the proper administration of the religion, and went on to propagate his own teachings among a group of followers that observers say probably never exceeded 200. but declined in size significantly from 1990-1996. During his lifetime adherents were mostly concentrated in Montana, with smaller groups in other states.

Jensen gained national attention when on April 26, 1980 he led a group of followers into fallout shelters, expecting an apocalyptic nuclear holocaust. He went on to predict that Halley's Comet would enter earth's orbit on April 29, 1986, and collide with the earth exactly one year later. With Jensen's approval, in the early 1990s his companion Neal Chase made a total of 18 predictions which pertained to small-scale disasters that he claimed would lead step-by-step towards the Apocalypse, as well as dates for a nuclear attack on New York City by middle Eastern terrorists.
