By the time European-American settlers began to arrive in the Shenandoah Valley (c. 1730) of Virginia, the Shawnee predominated in the northern part of the valley. They were claimed as tributaries by the "Haudenosaunee" or Six Nations of the Iroquois to the north. The latter had helped some of the Tuscarora people from North Carolina, who were also Iroquoian speaking and distant relations, to resettle in the vicinity of what is now Martinsburg, West Virginia. Most of the Tuscarora migrated to New York and settled near the Oneida people, becoming the sixth nation of the Iroquois Confederacy; they declared their migration finished in 1722. Also at this time, Seneca (an Iroquois nation) and Lenape war parties from the north often fought pitched battles with pursuing bands of Catawba from Virginia, who would overtake them in the Shawnee-inhabited regions of the Valley.
