Document 3: History of the Southern United States: The history of the Southern United States reaches back hundreds of years and includes the Mississippian people, well known for their mound building. European history in the region began in the very earliest days of the exploration and colonization of North America. Spain, France, and England eventually explored and claimed parts of what is now the Southern United States, and the cultural influences of each can still be seen in the region today. In the centuries since, the history of the Southern United States has recorded a large number of important events, including the American Revolution, the American Civil War, the ending of slavery, and the American Civil Rights Movement.

Document 5: John Alexander Austin House: The John Alexander Austin House is a historic house in Memphis, Tennessee, U.S..

Document 6: Mississippi Delta: The Mississippi Delta is the distinctive northwest section of the U.S. state of Mississippi which lies between the Mississippi and Yazoo Rivers. The region has been called "The Most Southern Place on Earth" ("Southern" in the sense of "characteristic of its region, the American South"), because of its unique racial, cultural, and economic history. It is 200 miles long and 87 miles across at its widest point, encompassing circa 4,415,000 acres, or, some 7,000 square miles of alluvial floodplain. Originally covered in hardwood forest across the bottomlands, it was developed as one of the richest cotton-growing areas in the nation before the American Civil War (1861-1865). The region attracted many speculators who developed land along the riverfronts for cotton plantations; they became wealthy planters dependent on the labor of black slaves, who comprised the vast majority of the population in these counties well before the Civil War, often twice the number of whites.
Document 7: List of plantations in West Virginia: Plantations that operated within the present-day boundaries of West Virginia were located in the counties of the Ridge-and-Valley Appalachians and in the Kanawha and Ohio River valley regions. Beginning in the mid-to-late 18th century, members of the Washington family and other prominent Virginia families began to build elegant Georgian mansions on their plantations in the Ridge-and-Valley Appalachians region of present-day West Virginia. Plantations initially developed in the counties lying within the Northern Neck Proprietary of Thomas Fairfax, 6th Lord Fairfax of Cameron within the Shenandoah Valley and South Branch Potomac River valleys. Slavery as practiced through plantations in the American South was carried over from the plantations of the Piedmont and Tidewater regions of Virginia, where plantations had become the foundation of society and industry. Following the French and Indian War, settlement and agricultural development continued unabated in the Shenandoah and South Branch Potomac valleys. Early instances of western Virginia plantations with grand homes include the John Ariss-designed Harewood (1774) for George Washington's brother Samuel Washington and Happy Retreat (1780) built by Washington's younger brother Charles Washington, both of which are located near Charles Town in present-day Jefferson County. In Hampshire County, Nicholas Casey constructed a Georgian mansion (1774) at his Wappocomo plantation, one of the first plantation houses of its kind in the South Branch Potomac River valley.

Document 9: Slavery by Another Name: Slavery by Another Name: The Re-Enslavement of Black Americans from the Civil War to World War II is a book by American writer Douglas A. Blackmon, published by Anchor Books in 2008. It explores the forced labor of imprisoned black men and women, through the convict lease system used by states, local governments, white farmers, and corporations after the American Civil War until World War II in the southern United States. Blackmon argues that slavery in the United States did not end with the Civil War, but instead persisted well into the 20th century. It depicts the subjugation of Convict Leasing, Sharecropping and Peonage and tells the fate of the former but not of the latter two.

Known as the "Father of Texas", and the founder of Texas, he led the second, and ultimately, the successful colonization of the region by bringing 300 families from the United States to the region in 1825.
Document 12: King Cotton: "King Cotton" as a slogan summarized the strategy used before the American Civil War of 1861–1865 by pro-secessionists in the Southern States (the future Confederacy) to claim the feasibility of secession and to prove there was no need to fear a war with the Northern States. The theory held that control over cotton exports would make a proposed independent Confederacy economically prosperous, would ruin the textile industry of New England, and—most importantly—would force Great Britain and perhaps France to support the Confederacy militarily because their industrial economies depended on Southern cotton. The slogan, widely believed throughout the South, helped in mobilizing support for secession: by February 1861, the seven states whose economies were based on cotton plantations had all seceded and formed the Confederacy (C.S.A.). Meanwhile, the other eight slave states, with little or no cotton production, remained in the Union.
Document 13: Plantations in the American South: Plantations were an important aspect of the history of the American South, particularly the antebellum (pre-American Civil War) era. The mild subtropical climate, plentiful rainfall, and fertile soils of the American Southeast allowed large plantations to flourish; where large numbers of workers, usually Africans held captive for slave labor, were required for agricultural production.
Document 14: Alexander Fulton (Louisiana): Alexander Fulton (died c. 1818) was a merchant, planter, and local politician originally from Washington, near Pittsburgh in western Pennsylvania, who in 1805 founded the city of Alexandria, Louisiana, which he named for himself.
Document 15: African-American teachers: African-American teachers educated African Americans and taught each other to read during slavery in the South. Slaves ran small schools in secret, since teaching a slave to read was a crime (see Slavery in the United States#Slave codes). While, in the North, African Americans worked alongside with Whites. Many privileged African Americans in the North wanted their children taught with White children, and were pro-integration. The Black middle class preferred segregation. During the post-Reconstruction era African Americans built their own schools so they didn't have White control. The Black middle class believed that it could provide quality education for their community. This resulted in the foundation of teaching as a profession for Blacks. Some Black families had multiple individuals who dedicated their lives to teaching. They felt that they could empower their communities. In the late 19th and early 20th centuries, Southern States passed Jim Crow laws to mandate racial segregation in all aspects of society, and prevent Blacks from voting. Racism made it difficult for Black professionals to work in other professions. In 1950, African American teachers made up about half of African-American professionals.
