Final answer:
The answer is 1) plantations, New Orleans, which became a significant urban center in the South due to the cotton trade, with many northern bankers financing southern plantations.
Step-by-step explanation:
Many southern cities became centers for shipping rather than for industrial manufacturing. Many northern bankers financed southern plantations. Because of the lack of industrialization, in the cotton kingdom, the only city of significant size was New Orleans. The correct answer to the fill-in-the-blank question is: 1) plantations, New Orleans. Before the Civil War, the South focused on agricultural production, using slave labor to grow cotton, while the North developed industrial factories. In contrast, the South's lack of industrialization meant that fewer large cities developed there, and New Orleans stood out as a major, culturally diverse urban center driven by the cotton trade and banking capital. As the South transitioned post-war, cities like Atlanta and Birmingham grew, but it was the legacy of New Orleans that marks the historical period before significant southern industrialization.
