Mormon History Association
The Mormon History Association, an affiliate member of the American Historical Association and member of the Western History Association, is an independent, nonprofit organization dedicated to the study and understanding of all aspects of Mormon history.
The Mormon History Association (MHA) was founded in December 1965 at the American Historical Association meeting under the leadership of Leonard J. Arrington, a noted historian. MHA was “organized to promote understanding, scholarly research, and publication in the field of Mormon History.” The association welcomes all who are interested in the “Mormon” past, “irrespective of religious affiliation, academic training, or world location.”
In 1972 it became an independent organization with its own annual conferences and publications. In 1974, The Journal of Mormon History, an official publication, began publication.
According to Wikipedia, members of MHA are composed of people both within and without The Church of Jesus Christ of Latter-day Saints and the Community of Christ, including those who reject the restored gospel of Jesus Christ.
