Review Questions

  • How did the Interstate Slave Trade impact the population distribution of enslaved people within the United States?
    • The Interstate Slave Trade significantly altered the population distribution of enslaved people by facilitating their movement from the Upper South to the Deep South. This shift was driven by the rising demand for labor on expanding cotton plantations, which necessitated a larger workforce. As a result, regions like Virginia experienced a decrease in their enslaved population while states such as Alabama and Mississippi saw a substantial increase, ultimately shaping the demographics of slavery in America.
  • In what ways did economic factors drive the growth of the Interstate Slave Trade during the early republic?
    • Economic factors played a crucial role in driving the growth of the Interstate Slave Trade as agricultural demand soared, particularly with the rise of cotton as a cash crop. The profitability of cotton farming created an insatiable need for labor, prompting plantation owners to seek out additional enslaved workers through interstate trade. This economic motivation not only increased slave transactions but also strengthened slavery's entrenchment within Southern society, intertwining it with regional economic interests.
  • Evaluate how the existence of the Interstate Slave Trade influenced legislation and societal attitudes towards slavery in early 19th century America.
    • The Interstate Slave Trade deeply influenced both legislation and societal attitudes towards slavery by legitimizing and normalizing the practice within American society. As states engaged in this trade, they enacted laws such as slave codes that codified racial hierarchies and limited enslaved people's rights. Additionally, public opinion became increasingly polarized; while many in the South defended slavery as an economic necessity, abolitionist sentiments grew stronger in Northern states. This tension contributed to broader national conflicts over slavery that would eventually lead to civil strife.
