James Strang was a recent convert to the Latter Day Saint movement when founder Joseph Smith was assassinated in June 1844. Within days, Strang produced a letter he said Smith had written naming him as successor, a document most historians and the Church of Jesus Christ of Latter-day Saints itself regard as inauthentic rather than genuine.
That claim was enough to draw a minority of Smith's followers away from the main body that would coalesce around Brigham Young and the eventual migration west to Utah. Strang led his own splinter church first from a base in Wisconsin, then from 1848 relocated its center to Beaver Island, in Lake Michigan, where in 1850 he had himself formally crowned king of the settlement he had built there.
The claimed succession letter, contested from the moment Strang first produced it, remained the founding act on which his entire church rested. Everything that followed, the Wisconsin years, the move to Beaver Island and the kingship declared there in 1850, traced back to a single disputed document written in the immediate aftermath of Smith's assassination in Illinois, a claim his own church's opponents rejected from the start of his brief and contested rule.
