🌱 Early Life and Background

Joseph Smith Jr. was born on December 23, 1805, in Sharon, Vermont, into a large and poor farming family. The Smiths later moved to Palmyra, New York, part of the so-called “Burned-over District”, a region famous for religious revivals.

As a teenager, Joseph reported a series of divine visions, including the appearance of God the Father and Jesus Christ when he was just 14 years old. This event, known in LDS belief as the First Vision, marked the beginning of his spiritual journey.

📖 The Revelation of the Book of Mormon

At age 17, Joseph claimed that an angel named Moroni directed him to a buried set of golden plates inscribed with ancient writings. Over several years, he “translated” the plates into what became the Book of Mormon, published in 1830.

That same year, he formally founded the Church of Christ, later renamed the Church of Jesus Christ of Latter-day Saints.

Joseph kept many of his marriages secret, even from Emma initially. This caused significant tension within the church and led to lasting doctrinal splits after his death.

There are also claims of children from some plural wives, though conclusive evidence is limited.

🧠 Church Growth and Persecution

Smith’s church grew rapidly, attracting converts across the U.S. and Europe. But so did opposition, especially due to:

  • New theological claims

  • Secret polygamous practices

  • Smith’s political ambitions, including running for U.S. President in 1844

By the 1840s, the Mormons had established Nauvoo, Illinois, a thriving city with its own militia and charter. But tensions with non-Mormons escalated quickly.
