May 3, 1834
Kirtland, Ohio
Joseph Smith presided over a conference of elders that discussed the name by which the Church was to be known. The name was changed to The Church of the Latter-Day Saints (from Church of Christ) to distinguish it from other churches. The name was changed again by revelation on April 26, 1838, to The Church of Jesus Christ of Latter-day Saints.
