Following an election in 1995, the city of Augusta (the county seat) consolidated governments with Richmond County. The consolidated entity is known as Augusta-Richmond County, or simply Augusta. Exempt are the cities of Hephzibah and Blythe, in southern Richmond County, which voted to remain separate.
The county is named for Charles Lennox, 3rd Duke of Richmond, a British politician and office-holder sympathetic to the cause of the American colonies.  Richmond was also a first cousin to King George III.
Richmond County was established in 1777 by the first Constitution of the (newly independent) State of Georgia. As such, it is one of the original counties of the state. It was formed out of a portion of the colonial Parish of St. Paul, after the Revolution disestablished the Church of England in the (former) Royal Province of Georgia.
The vast majority of Richmond County is located in the Middle Savannah River sub-basin of the Savannah River basin, with just the southwestern corner of the county, from a line running north from Blythe through the middle of Fort Gordon, located in the Brier Creek sub-basin of the Savannah River basin.

Similar to most urban counties in the state with majority African American populations, Richmond County has backed the Democratic Party candidate by increasing margins since 1992. However in every presidential election from 1948 to 1988 which did not have Georgian Jimmy Carter on the ballot, the county backed the Republican candidate for president. Prior to 1948, the county voted like a typical Solid South county, voting for Democratic presidential candidates by landslide margins. 1928 was an exception to this rule with Herbert Hoover beating Al Smith handily due to anti-Catholic sentiment.
