Joseph Smith, Jr. was the founder of the Latter Day Saint movement, also known as Mormonism, and an important religious and political figure during the 1830s and 1840s. In 1827, Smith began to gather a religious following after announcing that an angel had shown him a set of golden plates describing a visit of Jesus to the indigenous peoples of the Americas. In 1830, Smith published what he said was a translation of these plates as the Book of Mormon, and the same year he organized the Church of Jesus Christ of Latter Day Saints.
For most of the 1830s, Smith lived in Kirtland, Ohio, which remained the headquarters of the church until Smith began encouraging members to gather the church to a Latter Day Saint settlement in Missouri. There, tensions between Mormons and non-Mormons resulted in the expelling of the Mormons. Smith and his people then settled in Nauvoo, Illinois where they began building a new temple aided by new converts from Europe. He was assassinated by a mob of non-Mormons at the age of 38.
Smith's followers consider him a prophet and have canonized some of his revelations as sacred texts on par with the Bible. His legacy as a leader of The Church of Jesus Christ of Latter-day Saints has been recognized by millions of adherents.
