Early-19th-century Mormonism, under the direction of founder Joseph Smith, and other prominent Mormon leaders such as Brigham Young, taught that a world government would exist upon the earth during the end times. The world government would be the political arm of the church, which was referred to as Zion or the Kingdom of God on earth. It was taught that this kingdom would rule over all the people of the earth, and would allow each individual to live under true freedom and liberty.
On March 11, 1844, Smith organized a Council of Fifty, which was to work under the direction of the priesthood authority of the church. A third body, the Council of Friends, would also exist. The Council of Friends was to be a three-member body which was to function as the political Kingdom of God just prior to the Second Coming of Jesus. The Second Coming would usher in the Millennium, a 1000-year period in which political power would reside with this world government.
The political and spiritual kingdoms of God were to be distinct entities, with "a constitutional separation of powers between Zion and the political government." The Council of Fifty was organized "for the maintenance, promulgation and protection of civil and religious liberty." The council was intended to act in a legislative capacity as a theodemocracy. The council's decisions could be vetoed by the church's priesthood authority. The third leg of the government, the Council of Friends, would act as advisors to both the Council of Fifty, and the priesthood body of the church. All three bodies were to be composed of righteous men.
The priesthood authority would yield veto power over the Council of Fifty, with ultimate power held by a single anointed individual. Smith was ordained "king" on April 11, 1844, and was thereby set to preside over the political kingdom of God. Smith was killed just over two months later, on June 27th, 1844.
