5th Oklahoma Legislature

The Fifth Oklahoma Legislature was a meeting of the legislative branch of the government of Oklahoma, composed of the Oklahoma Senate and the Oklahoma House of Representatives. The state legislature met in Oklahoma City, in regular session from January 5 to March 23, 1915, and in special session from January 17 to February 22, 1916, during the first two years of the term of Governor Robert L. Williams. The legislature included six Socialists, who only served for a single term. The only bill sponsored by a Socialist that became Oklahoma law involved hunting. The 1916 special session was called after the U.S. Supreme Court struck down Oklahoma's Jim Crow law.
Lieutenant Governor Martin E. Trapp served as the President of the Senate and E. L. Mitchell served as the President pro tempore of the Oklahoma Senate. Alonzo McCrory served as Speaker of the Oklahoma House of Representatives.
