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.
Authors of books on "faith-promoting history" are criticized as generally avoiding more controversial topics in an effort to promote faith among members. This sort of history has generally been endorsed by the leadership of The Church of Jesus Christ of Latter-day Saints (LDS Church), and was encouraged by church apostle Dallin H. Oaks.
On the opposite end of the spectrum are anti-Mormon historians, which Oaks mentioned in the above quote. Anti-Mormons generally write with the intention of disproving the claims of the LDS Church, sometimes to the point of fabricating lies about the LDS Church. Though such historians would not be considered Latter Day Saints, they could be considered Latter Day Saint historians as the LDS Church is the topic of their research. Many anti-Mormons are, in fact, non-practicing ex-Mormons and therefore may still consider themselves cultural Mormons.
Other historians reject both faith-promoting history and anti-Mormon history, and seek to give a more objective analysis, basing their conclusions on actual evidence, rather than revealing selective evidence to reach their desired conclusions.
