Question: The founder of Mormonism and the Latter Day Saint movement founded what church in 1830?

Context paragraphs:
Children of Joseph Smith: The children of Joseph Smith Jr., the founder of the Latter Day Saint movement, and his wife Emma Smith, are historically significant because of their roles in establishing and leading the Latter Day Saint Movement, which includes The Church of Jesus Christ of Latter-day Saints (LDS Church), the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church, now called Community of Christ), The Church of Jesus Christ (Bickertonite), the Church of Christ (Temple Lot) and several other sects.  Several Latter Day Saint sects, including the RLDS believed that leadership of the church would flow through Smith's descendants, (Lineal succession).  In 1860, Joseph Smith III became its prophet and president of the RLDS Church.  The larger LDS Church was led following Joseph's death by Brigham Young.

Church of Christ (Hancock): The Church of Christ, informally referred to as the Church of Christ (Hancock), the Basement Church, the Church of Christ (Lukeite) and the Church of Christ (Bible and Book of Mormon Teaching), was a sect of the Latter Day Saint movement founded in Independence, Missouri in 1946 by Pauline Hancock.  This church, which became defunct in 1984, bears the distinction of being the first Latter Day Saint sect to be founded by a woman.  Among its members were Jerald and Sandra Tanner, who later became well-known opponents of the Latter Day Saint movement with their "Utah Lighthouse Ministry".

List of prophecies of Joseph Smith: Joseph Smith, the founder of the Latter Day Saint movement, is viewed by adherents of the Latter Day Saint movement as a prophet in the tradition of the ancient prophets recorded in the Bible.  During his life, Smith made several prophecies, many documented in the Doctrine and Covenants, a book of scripture in several denominations of the Latter Day Saint movement.

Temple (Latter Day Saints): In the Latter Day Saint movement, a temple is a building dedicated to be a house of God and is reserved for special forms of worship.  A temple differs from a church meetinghouse, which is used for weekly worship services.  Temples have been a significant part of the Latter Day Saint movement since early in its inception.  Today, temples are operated by several Latter Day Saint denominations.  The most prolific builder of temples of the Latter Day Saint movement is The Church of Jesus Christ of Latter-day Saints (LDS Church).  There are 157 operating temples (which includes 2 previously dedicated, but closed for renovation), 12 under construction, and 13 announced (not yet under construction).  Several other variations of the church have built or attempted to build temples.  The Community of Christ operates two temples in the United States, which are open to the public and are used for worship services, performances, and religious education.  Other denominations with temples are the Apostolic United Brethren, the Church of Christ, the Fundamentalist Church of Jesus Christ of Latter-Day Saints and the Righteous Branch of the Church of Jesus Christ of Latter-day Saints.

Latter Day Saint movement: The Latter Day Saint movement (also called the LDS movement, LDS restorationist movement, or Smith–Rigdon movement) is the collection of independent church groups that trace their origins to a Christian primitivist movement founded by Joseph Smith in the late 1820s.  Collectively, these churches have over 15 million members.  The vast majority of adherents belong to The Church of Jesus Christ of Latter-day Saints (LDS Church), with their predominant theology being Mormonism.  The LDS Church self-identifies as Christian.  A minority of Latter Day Saint adherents, such as members of the Community of Christ, believe in traditional Protestant theology, and have distanced themselves from some of the distinctive doctrines of Mormonism.  Other groups include the Remnant Church of Jesus Christ of Latter Day Saints, which supports lineal succession of leadership from Smith's descendants, and the more controversial Fundamentalist Church of Jesus Christ of Latter-Day Saints, which defends the practice of polygamy.

Historians of the Latter Day Saint movement: Historians of the Latter Day Saint movement are a diverse group of historians writing about Mormonism.  Historians devoted to the history of the Latter Day Saint movement may be members of a Latter Day Saint faith or non-members with an academic interest.  They range from faith-promoting historians to anti-Mormon historians, but also include scholars who make an honest effort at objectivity.

Joseph Smith: Joseph Smith Jr. (December 23, 1805 – June 27, 1844) was an American religious leader and founder of Mormonism and the Latter Day Saint movement.  When he was twenty-four, Smith published the Book of Mormon.  By the time of his death fourteen years later, he had attracted tens of thousands of followers and founded a religious culture that continues to the present.

General conference (Latter Day Saints): In the Latter Day Saint movement, a general conference is a meeting for all members of the church for conducting general church business and instruction.  When Joseph Smith established in Church of Christ in 1830, he was instructed by revelation that the church "are to meet in conference once in three months, or from time to time as said conferences shall direct or appoint; And said conferences are to do whatever church business is necessary to be done at the time."  The church met in conferences regularly until Smith's death in 1844.

Mormonism: Mormonism is the predominant religious tradition of the Latter Day Saint movement of Restorationist Christianity.  Joseph Smith founded the movement in Western New York in the 1820s.  During the 1830s and 1840s, it distinguished itself from traditional Protestantism.  Mormonism represents the faith taught by Smith in the 1840s.  After he was killed in 1844, most Mormons followed Brigham Young on his westward journey to the area that became the Utah Territory, calling themselves The Church of Jesus Christ of Latter-day Saints (LDS Church).  Other sects include Mormon fundamentalism, which seeks to maintain practices and doctrines such as polygamy, and various other small independent denominations.  The second-largest Latter Day Saint denomination, the Reorganized Church of Jesus Christ of Latter-day Saints, since 2001 called the Community of Christ, does not describe itself as "Mormon", but instead follows a Trinitarian Christian restorationist theology, and also considers itself Restorationist in terms of Latter Day Saint doctrine.

Mormon cosmology: Mormon cosmology is the description of the history, evolution, and destiny of the physical and metaphysical universe according to Mormonism, which includes the doctrines taught by leaders and theologians of The Church of Jesus Christ of Latter-day Saints (LDS Church), Mormon fundamentalism, the Restoration Church of Jesus Christ, and other Brighamite denominations within the Latter Day Saint movement.  Mormon cosmology draws from Biblical cosmology, but has many unique elements provided by movement founder Joseph Smith.  These views are not generally shared by adherents of other Latter Day Saint movement denominations who do not self-identify as "Mormons", such as the Community of Christ.
