History of the Southern United States in the context of "Mississippian culture"

Louisiana was a dominant population center in the southwest of the Confederate States of America, controlling the wealthy trade center of New Orleans, and contributing the French Creole and Cajun populations to the demographic composition of a predominantly Anglo-American country. In the antebellum period, Louisiana was a slave state, where enslaved African Americans had comprised the majority of the population during the eighteenth-century French and Spanish dominations. By the time the United States acquired the territory (1803) and Louisiana became a state (1812), the institution of slavery was entrenched. By 1860, 47% of the state's population were enslaved, though the state also had one of the largest free black populations in the United States. Much of the white population, particularly in the cities, supported slavery, while pockets of support for the U.S. and its government existed in the more rural areas.

Louisiana declared that it had seceded from the Union on January 26, 1861. Civil-War era New Orleans, the largest city in the South, was strategically important as a port city due to its southernmost location on the Mississippi River and its access to the Gulf of Mexico. The U.S. War Department early on planned for its capture. The city was taken by U.S. Army forces on April 25, 1862. Because a large part of the population had Union sympathies (or compatible commercial interests), the U.S. government took the unusual step of designating the areas of Louisiana then under U.S. control as a state within the Union, with its own elected representatives to the U.S. Congress. For the latter part of the war, both the U.S. and the Confederacy recognized their own distinct Louisiana governors. Similarly, New Orleans and 13 named parishes of the state were exempted from the Emancipation Proclamation, which applied exclusively to states in rebellion against the Union.

A plantation complex was a large-scale agricultural estate, common in the Americas from the 17th to the 20th century, that was structured as a self-sufficient community to produce cash crops for profit. Plantation complexes were common on agricultural plantations in the Southern United States from the 17th into the 20th century. The complex included everything from the main residence down to the pens for livestock. Until the abolition of slavery, such plantations were generally self-sufficient settlements that relied on the forced labor of enslaved people.

Plantations are an important aspect of the history of the Southern United States, particularly before the American Civil War. The mild temperate climate, plentiful rainfall, and fertile soils of the Southeastern United States allowed the flourishing of large plantations, where large numbers of enslaved Africans were held captive and forced to produce crops to create wealth for the planter class, normally a white elite.

The Antebellum South era (from Latin: ante bellum, lit. 'before the war') was a period in the history of the Southern United States that extended from the conclusion of the War of 1812 to the start of the American Civil War in 1861. This era was marked by the prevalent practice of slavery and the associated societal norms it cultivated. Over the course of this period, Southern leaders underwent a transformation in their perspective on slavery. Initially regarded as an awkward and temporary institution, it gradually evolved into a defended concept, with proponents arguing for its positive merits, while simultaneously vehemently opposing the burgeoning abolitionist movement.

Society was stratified, inegalitarian, and perceived by immigrants as lacking in opportunities. Consequently, the manufacturing base lagged behind that of the non-slave states. Wealth inequality grew as the larger landholders took the greater share of the profits generated by enslaved persons, which also helped to entrench their power as a political class.
