The best explanation of the effects of the Yamasee War on the restructuring of settlements and shift in power in South Carolina is: Indigenous power declined, while colonial power increased.
The Yamasee War (1715-1717) was a conflict between Native American tribes and British colonists in South Carolina. Following the war, many Indigenous groups lost their influence and territories, while British colonial authority solidified and grew stronger in the region. This shift facilitated the expansion of settlements and the establishment of greater control by colonial powers over the land and trade.
