Augustus Octavius Bacon was a Confederate soldier, segregationist, and U.S. politician. A member of the Democratic Party, he served as a U.S. senator from Georgia, becoming the first senator to be directly elected after the ratification of the 17th Amendment, and rose to the position of president pro tempore of the United States Senate. Controversy arose during the American Civil Rights Movement over a provision in his will that created a racially segregated park in his hometown of Macon, which led to two U.S. Supreme Court decisions. He was a slave owner.

The Seventeenth Amendment to the United States Constitution established the direct election of United States senators in each state. The amendment supersedes Article I, Section 3, Clauses 1 and 2 of the Constitution, under which senators were elected by state legislatures. It also alters the procedure for filling vacancies in the Senate, allowing for state legislatures to permit their governors to make temporary appointments until a special election can be held.
