At a conference on April 6, 1860, at Amboy, Illinois, Smith III formally accepted the leadership of what was then known as the Church of Jesus Christ of Latter Day Saints. William Marks, former stake president of Nauvoo, served as Smith III's counselor in the reorganized First Presidency. The word "Reorganized" was added to the church's official name in 1872, mostly as a means of distinguishing it from the larger LDS Church, which at that time was involved in controversy with the U.S. government over its doctrine of plural marriage. The Reorganized Church of Jesus Christ of Latter Day Saints was often abbreviated "RLDS Church".
