A Comprehensive History of The Church of Jesus Christ of Latter-day Saints: Century I is a six-volume history published in 1930 by B.H. Roberts, a general authority and Assistant Church Historian of the LDS Church. It should not be confused with the seven-volume History of the Church of Jesus Christ of Latter-day Saints (nicknamed Documentary History of the Church), which was also edited by Roberts in the early 20th-century but focuses on the history of Joseph Smith.
