Sidney Sanders McMath was a U.S. marine, attorney and the 34th governor of Arkansas from 1949 to 1953. In defiance of his state's political establishment, he championed rapid rural electrification, massive highway and school construction, the building of the University of Arkansas for Medical Sciences, strict bank and utility regulation, repeal of the poll tax, open and honest elections and broad expansion of opportunity for black citizens in the decade following World War II.

The States' Rights Democratic Party was a short-lived segregationist political party in the United States, active primarily in the South. It arose due to a Southern regional split in opposition to the regular Democratic Party. After President Harry S. Truman, the leader of the Democratic Party, ordered integration of the military in 1948 and other actions to address civil rights of African Americans, including the first presidential proposal for comprehensive civil and voting rights, many Southern white politicians who objected to this course organized themselves as a breakaway faction. They wished to protect the ability of states to maintain racial segregation. Its members were referred to as "Dixiecrats", a portmanteau of "Dixie", referring to the Southern United States, and "Democrat".
