Henry Louis Bellmon was an American Republican politician from the U.S. State of Oklahoma. A member of the Oklahoma Legislature, he went on to become both the 18th and 23rd governor of Oklahoma, mainly in the 1960s and again in the 1980s, as well as a two-term United States Senator in the 1970s. He was the first Republican to serve as Governor of Oklahoma and, after his direct predecessor George Nigh, only the second governor to be reelected.

The Legislature of the State of Oklahoma is the state legislative branch of the U.S. state of Oklahoma. The Oklahoma House of Representatives and Oklahoma Senate are the two houses that make up the bicameral state legislature. There are 101 state representatives, each serving a two-year term, and 48 state senators, who serve four-year terms that are staggered so only half of the Oklahoma Senate districts are eligible in each election cycle. Legislators are elected directly by the people from single member districts of equal population. The Oklahoma Legislature meets annually in the Oklahoma State Capitol in Oklahoma City.
