In the theology and cosmology of Mormonism, in heaven there are three degrees of glory which are the ultimate, eternal dwelling places for nearly all who have lived on earth after they are resurrected from the spirit world.

Mormonism is the theology and religious tradition of the Latter Day Saint movement of Restorationist Christianity started by Joseph Smith in Western New York in the 1820s and 1830s. As a label, Mormonism has been applied to various aspects of the Latter Day Saint movement, although there has been a recent push from the Church of Jesus Christ of Latter-day Saints to distance themselves from this label. A historian, Sydney E. Ahlstrom, wrote in 1982 that, depending on the context, the term Mormonism could refer to “a sect, a mystery cult, a new religion, a church, a people, a nation, or an American subculture; indeed, at different times and places it is all of these."
