History

Oklahoma County was originally called County Two and was one of seven counties established by the Organic Act of 1890.^[4]

County business initially took place in a building at the intersection of California Avenue and Robinson Street until the construction of the first Oklahoma County Courthouse at 520 West Main Street in the 1900s. In 1937, the county government was moved to a building at 321 Park Avenue, which now serves only as the county courthouse.^[5]

Politics

Oklahoma County, as is typical for the state, is very conservative for an urban county. Reflecting the state's turn toward the GOP in the second half of the 20th century, it swung from a 29-point victory for Harry Truman in 1948 to a 15-point victory for Dwight Eisenhower in 1952. It has gone Republican in all but one presidential election since then; it narrowly voted for Lyndon Johnson in 1964. Contrasting with earlier years, in the 2018 Oklahoma gubernatorial election, Oklahoma County gave Democratic candidate Drew Edmondson the largest vote share of any county.
