These various claims resulted in a succession crisis, in which the majority of church members followed Brigham Young, he being the senior Apostle of the church; others followed Sidney Rigdon or James Strang. The crisis resulted in several permanent schisms as well as the formation of occasional splinter groups, some of which no longer exist. These various groups are occasionally referred to under two geographical headings: "Prairie Saints" (those that remained in the Midwest United States) and "Rocky Mountain Saints" (those who followed Brigham Young to what would later become the state of Utah). Today, there are many schism organizations who regard themselves as a part of the Latter Day Saint movement, though in most cases they do not acknowledge the other branches as valid and regard their own tradition as the only correct and authorized version of the church Smith founded. The vast majority of Latter Day Saints belong to the largest denomination, The Church of Jesus Christ of Latter-day Saints (LDS Church) which claims 16 million members worldwide. The second-largest denomination is the Community of Christ, which reports over 250,000 members.
