As of 2014, The Church of Jesus Christ of Latter-day Saints reported 45,734 members, seven stakes, 86 congregations (57 wards and 25 branches), one mission, and one temple in Oklahoma.
The history of the denomination in what would become Oklahoma begins in the 1840s and the Indian Territory Mission was created and placed under the leadership of George Miller in 1855. The first temple in Oklahoma was dedicated in 2000.
The eight stakes based in Oklahoma are located in Bartlesville, Lawton, Norman, Oklahoma City, Stillwater and Tulsa.
In the late 1840s, George Miller, a former bishop who delayed going to the West, traveled from Winter Quarters to visit his son in Texas. He and two other members with him, Joseph Kilting and Richard Hewitt, found construction work available in the Cherokee Nation. They arrived in Tahlequah on July 9, 1847, and began to build houses. They also began to teach others about the Mormon faith, but antagonism forced Miller to leave in December. Hewitt and Kilting remained to work.
In 1855, Orson Spencer and James McGaw visited the Indian Territory from St. Louis, Missouri, and on April 8, five more missionaries were sent from Salt Lake City, and four from St. Louis. The Indian Territory Mission was created and placed under the leadership of Miller on June 26, 1855.
