Context paragraphs:
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.

Đồng Khởi Movement: Đồng Khởi was a movement led by members of the Việt Minh in Southern Vietnam who urged people to revolt against the United States and the Republic Of Vietnam, first of all in large rural areas in southern Vietnam and on Highlands of South Central Coastal Vietnam.  This movement took place from the end of 1959, culminating in 1960, rapidly spreading across the South, dissolving the rural government structure of the Government of the Republic of Vietnam under President Ngo Dinh Diem, leading to a significant part of rural Southern Vietnam gained control by the communists, leading to the founding of the Southern Vietnam National Liberation Front.

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.  In 1991, Nicholas Lemann wrote that the Great Migration:

Barnett-Aden Gallery: The Barnett-Aden Gallery was a nonprofit art gallery in Washington D.C. founded by James V. Herring and Alonzo J. Aden, the founder and first curator, respectively of Howard University's Gallery of Art.  The gallery, officially incorporated on August 19, 1947, was one of the first African American galleries of art in the United States.  Artists featured in the collection include Edward Mitchell Bannister, Jacob Lawrence, Laura Wheeler Waring, Romare Bearden, Henry O. Tanner and Bernice Cross.  The collection featured artists of every race, particularly African American artists whose work was shown in few other venues. " ...there were few such opportunities in the years following World War II...in those bleak years, the Barnett-Aden Gallery was one of the few private galleries where Black painters, sculptors and graphic artists had a continuing opportunity to expose their works.”

Migration Series: The Migration Series, originally titled The Migration of the Negro, is a group of paintings by African-American painter Jacob Lawrence which depicts the migration of African Americans to the northern United States from the South that began in the 1910s.  It was published in 1941 and funded by the WPA.

Jacob L. Shuford: Jacob Lawrence Shuford (b. circa 1952) was a rear admiral of the United States Navy.  His career included service in the Cold War, Kosovo War, and Operation Desert Fox.  He commanded surface combatants, served on the staffs of the Chief of Naval Operations, the Joint Chiefs of Staff, and the Secretary of the Navy, coordinated Navy legislative activities in the United States Senate, and his final assignment as President of the Naval War College.

League of the South: The League of the South is a white nationalist and white supremacist organization, headquartered in Killen, Alabama, which states that its ultimate goal is "a free and independent Southern republic".  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.  It advocates a "natural societal order of superiors and subordinates", using as an example, "Christ is the head of His Church; husbands are the heads of their families; parents are placed over their children; employers rank above their employees; the teacher is superior to his students, etc."

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.

Black Southerners: Black Southerners are African-Americans living in the Southern United States, the region that has the largest population of African-Americans in the United States.

Henry Cabot Lodge Bohler: Henry Cabot Lodge Bohler (June 8, 1925 – August 10, 2007) was a member of the prestigious Tuskegee Airmen during World War II who would later aid the advancement of civil rights for African-Americans living in the rural Southern United States.
