This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
United States gathers twenty two cities, the atlas's largest single country grouping, holding both homegrown American religious movements and a long run of Roman Catholic diocesan seats.
Salt Lake City is Latter-day Saint headquarters since Brigham Young's 1847 pioneer company reached it after the exodus from Nauvoo. Independence, near Kansas City, is the Center Place of Joseph Smith's 1831 revelation, seat of the Temple Lot's Church of Christ and of Community of Christ; Saint Louis, founded by French Catholics in 1764, staged the same westward exodus. Boston's Mother Church anchors Christian Science after Mary Baker Eddy's 1879 founding and seeded Unitarianism; Kansas City is home to Unity, founded there in 1889 by Charles and Myrtle Fillmore.
Los Angeles hosted the 1906 Azusa Street Revival that most world Pentecostalism traces to, and later drew Yogananda's Self-Realization Fellowship, Aimee Semple McPherson's Angelus Temple and the Church of Scientology. Chicago's 1893 World's Parliament of Religions first gathered many traditions on one platform, introducing Vivekananda's Vedanta to America. New York, chief sea gateway for arriving traditions, holds the largest Jewish population outside Israel, Harlem's gospel churches, the Nation of Islam and the West's first Hare Krishna temple. Pittsburgh's 1885 platform set American Reform Judaism's course for a half century. San Diego holds the first California mission, founded by Junipero Serra in 1769, and was the site of the 1997 Heaven's Gate deaths.
Thirteen more, Milwaukee, Wilmington, Rochester, Syracuse, Camden, Harrisburg, Norwich, Helena, Santa Fe, New Ulm, Duluth, Gallup and Stockton, are ordinary Catholic cathedral or diocesan seats spread coast to coast beside the movements the other nine cities gave birth to.
