Early years The
Oklahoma Constitution established both the Oklahoma House of Representatives and
Oklahoma Senate in 1907. It met in
Guthrie until 1910. A weakening of the Democratic coalition leading up to the 1908 election allowed Republicans to make gains in the Oklahoma House. Republicans gained an even third of the legislative seats. The largest gains came in Holdenville, Okmulgee, and Guthrie, each of which had a sizable African-American population. The Democratic Party also pushed to make Oklahoma City the capital over Guthrie, a Republican and African-American voting stronghold. Cruce escaped an impeachment trial by one vote of the House investigative committee. In 1920,
Bessie S. McColgin became the first woman elected to the Oklahoma House of Representatives. A Republican, McColgin and her female colleague in the Oklahoma Senate, focused on the passage of public health bills, but failed in many of their efforts. After eight Democratic-controlled Legislatures, Republicans took the majority from 1921 to 1922 and elected
George B. Schwabe as
Speaker of the Oklahoma House of Representatives. The
Republican-dominated House brought impeachment charges against Lieutenant Governor
Martin Trapp and narrowly failed to approve impeachment charges against both the state treasurer and Oklahoma Governor James Roberts. The
Democratic-dominated Senate did not sustain the impeachment charges against Trapp. Members of the Oklahoma House of Representatives voted eleven articles of impeachment against Governor
Henry S. Johnston, which led to his expulsion from office.
1930s through 1950s A severe drought beginning in 1932 in western Oklahoma combined with land consolidation and mechanization in eastern Oklahoma drove farmers out of the state and left others in economic distress. Legislatures of the 1930s battled with governors
William H. Murray and
Ernest W. Marland, targeting Murray's efforts to generate relief for farmers and Marland's proposals to create a state public works program, reform the tax code and create unemployment insurance. Ever since voters approved the state question, the state legislature has been constitutionally required to pass a balanced budget. The number of
Republican Party seats in the Oklahoma House of Representatives plummeted in the 1930s.
1960s to present The legislative sessions held by the Oklahoma House of Representatives and
Oklahoma Senate changed due to two key legislative reforms in 1966 and 1989. In 1966, Oklahomans voted to institute 90-day annual sessions. An initiative petition championed by Governor
Henry Bellmon in 1989 further required the legislative sessions to end by 5 p.m. on the last Friday in May. A shift in the behavior of Oklahoma voters occurred, beginning in the 1960s. Registered Democrats began to more often vote Republican at the federal level and later at state level. As partisan debate became more polarizing, southern states including Oklahoma abandoned old voting patterns of supporting the Democratic party. After the
2004 Presidential Election,
Republicans gained control of the House for the first time since 1921. In 2010, Republicans gained a large majority of 70 seats in the Oklahoma House of Representatives. Following the 2018 general election, Republicans gained the largest majority in state history with 76 of the 101 seats. This also includes the largest ever freshman class, with 46 new representatives. ==Powers and legislative process==
