Macon (), officially Macon–Bibb County, is a consolidated city-county in the U.S. state of Georgia. Macon lies near the state's geographic center, about 85 miles (137 km) southeast of Atlanta—hence the city's nickname, "The Heart of Georgia". Located near the fall line of the Ocmulgee River, Macon had a 2019 estimated population of 153,159. It is the principal city of the Macon Metropolitan Statistical Area, which had an estimated population of 228,914 in 2017. Macon is also the largest city in the Macon–Warner Robins Combined Statistical Area (CSA), a larger trading area with an estimated 420,693 residents in 2017; the CSA abuts the Atlanta metropolitan area just to the north. In a 2012 referendum, voters approved the consolidation of the governments of the City of Macon and Bibb County, and Macon became Georgia's fourth-largest city (just after Columbus). The two governments officially merged on January 1, 2014.Macon is served by three interstate highways: I-16 (connecting the city to Savannah and coastal Georgia), I-75 (connecting the city with Atlanta to the north and Valdosta to the south), and I-475 (a city bypass highway). The city has several institutions of higher education, as well as numerous museums and tourism sites. The area is served by Middle Georgia Regional Airport and Herbert Smart Downtown Airport.

The Slocum Massacre occurred on July 29-30, 1910 in Slocum, Texas. Only six deaths were officially confirmed, but it is estimated as many as one hundred African Americans lost their lives in this massacre. Historians have provided several explanations for the motives of the all-white perpetrators of the massacre. When the story spread, it was altered to favor the white suspects and the black residents of Slocum were blamed. The whites from the mob did their best to destroy any evidence against them. African Americans reached out to higher levels of government for a fair investigation, but little to nothing was done on their behalf. As a result, the African American population in Slocum, Texas declined drastically.
