Joseph Smith (1805–1844) founded the Church of Jesus Christ of Latter-day Saints and authored the Book of Mormon, which he said came from golden plates revealed by an angel.
He moved his followers multiple times—from New York to Ohio, Missouri, and Illinois—seeking a place to build Zion, facing fierce opposition and violence along the way.
Smith was killed by a mob in 1844, but his movement survived and grew into a major American religion with millions of adherents today.

Joseph Smith Jr. was an American religious leader born in 1805 in Vermont who founded the Church of Jesus Christ of Latter-day Saints (commonly called the LDS or Mormon church). He claimed to have received divine revelations and translated an ancient text called the Book of Mormon, which became the scriptural foundation of his faith. Smith's life was marked by religious conviction, controversial practices, relentless opposition, and a violent death—all of which shaped the religion he created.

Early Life and the First Vision

Smith grew up in rural New York during a period of religious excitement called the Second Great Awakening. His family moved frequently and struggled financially. At age 14, Smith reported having a vision in which God the Father and Jesus Christ appeared to him, telling him that all existing churches were corrupt and that he would be the instrument of restoration. This experience, which he called the First Vision, became the cornerstone of his religious identity, though he did not publicly share details of it until years later.

The Book of Mormon and the Church's Founding

In 1823, Smith claimed an angel named Moroni visited him and revealed the location of golden plates containing a record of ancient peoples who lived in the Americas. Smith said he retrieved these plates in 1827 and spent the next two years translating them with divine aid. The result was the Book of Mormon, published in 1830, which describes pre-Columbian civilizations and their interactions with Jesus Christ. The same year, Smith formally organized the Church of Christ (later renamed the Church of Jesus Christ of Latter-day Saints) in Fayette, New York, with a handful of followers.

The translation process was collaborative. Smith dictated the text to scribes, most notably Oliver Cowdery and later his wife Emma Smith. Emma's role was particularly significant—she transcribed large portions of the Book of Mormon manuscript, and her meticulous work preserved the text during a period when the original plates were said to be hidden. Smith's method involved using a seer stone (a small stone he claimed allowed him to see the translation) or other devices, working behind a curtain or veil to shield the plates from view.

Building Zion and Facing Opposition

Smith believed God had commanded him to gather his followers and build Zion—a literal city of saints in America. This vision of a separate, religiously unified community alarmed non-Mormon neighbors. The church moved repeatedly: first to Ohio (1831), then Missouri (1838), and finally Illinois (1839). Each relocation was driven by conflict. In Missouri, violent clashes erupted between Mormons and anti-Mormon mobs, resulting in expulsions and deaths. Smith himself was arrested multiple times, jailed, and once nearly executed.

In Illinois, Smith founded Nauvoo, which became a thriving city of thousands. There, he introduced controversial doctrines including plural marriage (polygamy), which he claimed came from divine revelation. He also established secret temple rituals and began ordaining women to certain religious roles—practices that generated internal dissent and external scandal. His political ambitions and accumulation of power as mayor, militia commander, and religious leader made him an increasingly polarizing figure.

Death and Legacy

In 1844, Smith announced his candidacy for U.S. President. That same year, a dissident Mormon newspaper published accusations of polygamy and other grievances. Smith ordered the press destroyed, which triggered a legal crisis. On June 27, 1844, a mob stormed Carthage Jail in Illinois and killed Smith and his brother Hyrum. He was 38 years old. His death transformed him into a martyr figure within the church and solidified the movement's identity as a persecuted faith.

Smith's legacy is complex and contested. To his followers, he was a prophet who restored truths lost from early Christianity and produced scripture that continues to guide millions. To critics and historians, he was a charismatic con artist who manipulated followers, practiced deception, and exploited his authority. Regardless of interpretation, Smith's influence on American religion and culture is undeniable—he created a movement that survives and flourishes today, with the LDS Church claiming over 17 million members worldwide.

Did Joseph Smith actually translate the Book of Mormon from golden plates?

Smith claimed to translate it from plates revealed by an angel, but no one outside his immediate circle ever saw the plates. Scholars debate whether the text was a genuine translation, an inspired composition, or a literary work of Smith's own creation. The LDS Church maintains that Smith translated an ancient record; critics argue he authored it himself or drew from existing sources.

What was plural marriage, and why did Smith practice it?

Plural marriage (polygamy) was the practice of men taking multiple wives. Smith introduced it secretly around 1831 and claimed it came from divine revelation. He had at least 30 wives, some of whom were teenagers and some already married to other men. The practice was deeply controversial and contributed to violent opposition against the church. The LDS Church officially discontinued polygamy in 1890, though some fundamentalist offshoots continue the practice today.

Why were people so opposed to Joseph Smith and his followers?

Opposition stemmed from several sources: religious communities saw Mormonism as heretical; non-Mormons feared the church's political and economic bloc voting and land acquisition; Smith's practice of polygamy and secret rituals alarmed outsiders; and his claims of divine authority challenged existing religious hierarchies. Additionally, the church's goal of building a separate Zion threatened to disrupt established communities, leading to violence and expulsion in Missouri and Illinois.

What happened to the LDS Church after Joseph Smith died?

Brigham Young, one of Smith's closest associates, became the church's leader and led the majority of Mormons westward to the Great Salt Lake valley (now Utah) in 1847. The church continued to grow and eventually abandoned polygamy in 1890 to gain statehood for Utah. Today, the LDS Church is one of the largest and wealthiest religious organizations in America, with a global missionary presence and significant cultural influence.

Are there different versions of the Book of Mormon?

Yes. The original 1830 edition has been revised multiple times by the LDS Church, with changes made to grammar, phrasing, and doctrine. The LDS Church maintains these were clarifications and corrections; critics argue they represent substantive alterations that undermine Smith's claim of divine translation. Scholars have traced some passages to 19th-century sources, suggesting Smith may have borrowed from contemporary literature.
