Final answer:
During Amdetsion's expansion, the South and Southeast were impacted by the increasing European colonization and the contentious slave trade. The Mississippian culture's agricultural advancement allowed for dense populations, while Spanish missions sought to convert and control native populations. Tensions arose over the expansion of slavery, which was intricately tied to economic growth but morally debated within the U.S.
Step-by-step explanation:
During the expansion of Amdetsion, the South and Southeast regions were undergoing significant transformations. Coastal kingdoms, such as the Ashanti and the Dahomey, were contending with European colonial traders and invaders, who had superior firepower and technology. This era was marked by a flourishing slave trade that drew ships from various European countries to trade for gold, copper, ivory, and, predominantly, slaves. In addition to this, the expansion and transformation of the South occurred alongside the rapid growth of slave states in the Union between 1789 and 1860, bolstering economic growth built on slave labor. Furthermore, the European colonization, particularly the British, bolstered their presence in the South by engaging in lucrative Indian slave trade through ports such as Charles Town.
The Mississippian culture in the Southeast contributed significantly to early agricultural development, allowing dense populations to be supported by the surplus from corn-based agriculture. Meanwhile, Spanish missionaries sought to assert control in the region by establishing religious missions among the native populations, which also served as a source of labor. Slaveholders in the South, facing a ban on international slave trade, sought more territory for slave labor, causing tension over the moral and practical implications of expansionism in the United States.
