The Sweet Auburn is one of Atlanta's most historic neighborhoods, best known as the birthplace of 20th-century civil rights leader Martin Luther King, Jr. The district is one of more than 240 officially recognized neighborhoods in Atlanta and has been recognized as a National Historic Landmark District since the 1970s, spanning 19 acres throughout one of America's most historic African-American business districts. Its name was popularized in 1956 as the result of a Fortune magazine article about the neighborhood's ethnic affluence, originally coined by American civil rights leader John Wesley Dobbs. It is home to major Civil Rights Movement-related attractions such as the Martin Luther King Jr. Historic Site and the APEX Museum, which presents exhibits related to African-American history and culture. Hip restaurants and nightclubs line the Edgewood Avenue business district, while the annual Sweet Auburn Festival in May celebrates the neighborhood's African-American heritage.
