In 1913, Minnesota legislators began to be elected on nonpartisan ballots (1913 Minn. Laws Chap. 389). Legislators ran and caucused as "Liberals" or "Conservatives" (roughly equivalent in most years to Democratic-Farmer-Labor and Republican, respectively. A 1973 Law change brought back party designation elections beginning with the House in 1974 and the Senate in 1976 (1973 Minn. Laws Chapter 3 section 1; first numbered Minnesota Statute 202.03; renumbered Minnesota Statute 204B.36, subdivision 2).

Between November 15, 1975 and September 23, 1995, Minnesota Republicans ran under the party name Independent Republican.
