Six months after Strang's conversion, Joseph Smith, the president and prophet of the Mormons, was killed by an Illinois mob. At once there arose a desperate strife among the leaders, for the successorship to Joseph. Two of the number, Brigham Young and Strang, were men of ability, and the contest soon narrowed down to them. Young had the powerful support of the council of the church, known as "the twelve apostles"; but Strang produced a letter said to have been written by Joseph just before his death, in which Strang was named as his successor, with directions to lead the Mormons to a new "city of promise" in Wisconsin, to be called "Voree."
The "apostles" at Nauvoo denounced Strang as an impostor, declared that his letter was a forgery, and attacked him bitterly in their official newspapers, published at Nauvoo and at Liverpool, England. But Strang was not easily put down. A great many of the fanatics at Nauvoo believed in this impetuous young leader, who defended his cause with tact and forceful eloquence; and for a time it looked as if he might win.
However, in the end the "apostles" had their way, and the adroit Young was elected to the headship of the church. Strang at once called forth his followers, and in April, 1845, planted the "City of Voree" upon a prairie by the side of White River, in Walworth county, Wisconsin. It soon became a town of nearly two thousand inhabitants, who owned all things in common, but were ruled over, even in the smallest affairs of life, by the wily President Strang, who claimed to be divinely instructed in every detail of his rigorous government.
The people dwelt "in plain houses, in board shanties, in tents, and sometimes, many of them, in the open air." Great meetings were held at Voree, and the surrounding settlers gathered to hear Strang and his twelve "apostles" lay down the law, and tell of the revelations which had been delivered to them by the Almighty. Strang, who closely imitated the methods of Joseph, pretended to discover the word of God in deep-hidden records. Joseph had found the Book of Mormon graven upon plates dug out of the hill of Cumorah, in New York; so Strang discovered buried near Voree similar brazen plates bearing revelations, written in the rhythmic style of the Scriptures, which supplemented those in the Book of Mormon.
President Strang was a very busy man as the head of the Voree branch of the Mormon church. He obtained a printing outfit, and published a little weekly paper called Gospel Herald, besides hundreds of pamphlets, all written by himself, in which he assailed the "Brighamites" in the same violent manner as they attacked him in their numerous publications. He also, with his missionaries, conducted meetings in Ohio, New York, and other States in the East, gathering converts for Voree, and boldly repelling the wordy attacks of the Brighamites, whose agents were working the same fields.
Despite some backslidings, and occasional quarrels within its ranks, Voree grew and prospered. By 1849 there was a partially built stone temple there, which is thus described by an imaginative letter writer of the time: "It covers two and one-sixth acres of ground, has twelve towers, and the great hall two hundred feet square in the center. The entire walls are eight feet through, the floors and roofs are to be marble, and when finished it will be the grandest building in the world."
Nevertheless, it was early seen by Strang that the growing opposition of neighboring settlers would in the end cause the Mormons to leave Wisconsin, just as the Nauvoo fanatics were compelled (in 1846) to flee from Illinois, to plant their stake in the wilderness of the Far West.
He therefore made preparations for a place of refuge for his people, when persecutions should become unbearable. In journeying by vessel, upon one of his missions, he had taken note of the isolation of an archipelago of large, beautiful, well-wooded islands near the foot of Lake Michigan. The month of May, 1846, found him with four companions upon Beaver Island, in this far-away group. They built a log cabin, arranged for a boat, and returned to Voree to prepare for the migration of the faithful.
The new colony at first grew slowly, but by the summer of 1849 the "saints" began to arrive in goodly numbers. Strang himself now headed the settlement; and thereafter Voree ceased to be headquarters for the "Primitive Mormons," as they called themselves, although a few remained in the neighborhood.
Very soon, about two thousand devotees were gathered within the "City of St. James," on Beaver Island, with well-tilled farms, neat houses, a sawmill, roads, docks, and a large temple. A hill near by they renamed Mount Pisgah, and a River Jordan and a Sea of Galilee were not far away.
