text: Great Migration (African American) The Great Migration was the movement of 6 million African-Americans out of the rural Southern United States to the urban Northeast, Midwest, and West that occurred between 1916 and 1970. Until 1910, more than 90 percent of the African-American population lived in the American South. In 1900, only one-fifth of African-Americans living in the South were living in urban areas. By the end of the Great Migration, 53 percent of the African-American population remained in the South, while 40 percent lived in the North, and 7 percent in the West, and the African-American population had become highly urbanized. By 1970, more than 80 percent of African-Americans lived in cities, and by 1960, of those African-Americans still living in the South, half now lived in urban areas.

The collection featured artists of every race, particularly African American artists whose work was shown in few other venues.

text: White trash "White trash" is a derogatory American English racial slur referring to poor white people, especially in the rural southern United States. The label signifies lower social class inside the white population and especially a degraded standard of living. The term has been adopted for people living on the fringes of the social order, who are seen as dangerous because they may be criminal, unpredictable, and without respect for authority whether it be political, legal, or moral. The term is usually a racial slur, but may also be used self-referentially by working class whites to jokingly describe their origins or lifestyle.

The group defines the Southern United States as the states that made up the former Confederacy. It claims to be also a religious and social movement, advocating a return to a more traditionally conservative, Christian-oriented Southern culture.

text: Culture of Georgia (U.S. state) The culture of Georgia is a subculture of the Southern United States that has come from blending heavy amounts of rural Scots-Irish culture with the culture of African slaves and Native Americans. Since the late 20th century areas of Northern, Central, and the Atlanta metropolitan area of Georgia have experienced much growth from people moving from the mid-west and northeastern parts of the U.S.A. and along with many immigrants from Latin America. Southern culture remains prominent in the rural Southern and the Appalachian areas of the state. Georgians share a history with the other Southern States that includes the institution of slavery, the American Civil War, Reconstruction, the Great Depression, segregation, and the Civil Rights Movement.
