The Yamasee War (1715-1717) was a significant conflict between British colonists in South Carolina and various Indigenous groups, including the Yamasee. The war resulted in a decline in Indigenous power in the region, as many Native American tribes were either defeated, displaced, or weakened. In contrast, colonial power increased as British colonists solidified their control over the territory and expanded their settlements in the aftermath of the war.
