The Mid-America Union Conference is preceded by the Central Union (1902-1980) and the Northern Union (1902-1932, 1937-1980) conferences. The Central Union Conference was formed April 17, 1902 in Topeka, Kansas, and encompassed Colorado, Iowa, Kansas, Missouri, and Nebraska. The Northern Union Conference was also formed in April 1902 and included Minnesota, North Dakota, South Dakota, and Wyoming, United States; and Alberta, Manitoba, and Saskatchewan, Canada (in 1907 the Canadian provinces were restructured into the Western Canadian Union Conference, and Iowa Conference was added to the Northern Union).
