The Yamasee Indians were part of the Muskhogean language group. Their traditional homelands lay in present-day northern Florida and southern Georgia. The advent of the Spanish in the late 16th century forced the Yamasee to migrate north into what would become South Carolina. Relations between the tribe and English settlers in that region were generally positive during the latter half of the 17th century. Not surprisingly, problems between the races developed. The continuing influx of white settlers put pressure on Indian agricultural and hunting lands. The relationship was further complicated in that the tribe had become dependent on English firearms and other manufactured items, and had incurred a large debt, typically payable in deerskins. White fur traders acted on their displeasure by enslaving a number of Yamasee women and children to cover portions of the outstanding debt. In the spring of 1715, the Yamasee formed a confederation with other tribes and struck at the white settlements in South Carolina. Several hundred settlers were killed, homes burned and livestock slaughtered. The frontier regions were emptied; some fled to the relative safety of North Carolina and others pushed on to even more secure Virginia. Charleston also received large numbers of frightened settlers. At the height of the fighting, it appeared that the tribal confederation's overwhelming numerical superiority would end in the white settlements' complete destruction in the region. This would have been a virtual certainty if the confederacy had successfully drawn the Cherokee into their cause. Instead, the Cherokee gave in to the lure of English weapons and other goods, and chose to aid the Carolinians. In a further stroke of good fortune, the besieged settlers also managed to gain support from Virginia — an event not assured in this age of intense colonial rivalries. The tide turned against the Yamasee, who were slowly pushed south through Georgia back into their ancestral lands in northern Florida. There, the tribe was virtually annihilated by protracted warfare with the Creeks, but some members were absorbed by the Seminole. The Yamasee War took a heavy toll in South Carolina. Such terror had been instilled in the minds of the frontiersmen that it would take nearly 10 years for resettlement to occur in many areas. The warfare also brought a sharp change to the region's economy. Originally, farming had been the settlers' primary occupation, but the livestock supply had been so drastically depleted that many farms disappeared. In their absence, enterprising South Carolinians turned to the forests as a source of Naval Stores (tar, pitch and turpentine) and soon developed a lucrative trade with England. Later, the economy would develop rice and Indigo as its primary products.
