Christianity • Protestantism The United Sabbath-Day Adventist Church is a small African American Christian denomination founded by James K. Humphrey.
It formed in New York City as a breakaway from the Seventh-day Adventist Church in 1929–1930 over racial tensions between black and white people.
Its beliefs remained similar to Seventh-day Adventists.
At its peak in the 1930s the movement had 15 congregations and smaller "missions" throughout the United States and Jamaica.
As of 2007, a small number of people remain in a single congregation in New York City.
