The teachings of Joseph Smith include a broad spectrum of religious doctrines as well as political and scientific ideas and theories, many of which he said were revealed to him by God. Joseph Smith is the founder of the Latter Day Saint movement and is recognized by multiple Latter Day Saint churches as the founder. Beginning in 1828, Smith began dictating the text of what later became the Book of Mormon, and also began dictating written revelations he said were inspired by God.
Smith's teachings evolved over his lifetime until his death in 1844. Smith's teachings were published during his lifetime in several books, including the Book of Mormon, the Doctrine and Covenants (which included the Lectures on Faith), the Book of Abraham, and various essays he wrote in church newspapers. Many of his teachings were also published posthumously, including the transcription of sermons such as his King Follett Discourse, his writings in the official church history, and reminiscences of his teachings written by those who knew him.
