Treaty of Lancaster

The Treaty of Lancaster was a treaty concluded between the Haudenosaunee Confederacy (also known as "Six Nations" or Iroquois) and the colonial governments of Virginia Colony and Maryland Colony. Negotiations began at Lancaster, Pennsylvania, on June 25, and ended on July 4, 1744.

The negotiations were conducted in the old courthouse, which stood in the center of Lancaster at the time. The Soldiers and Sailors Monument, built in 1874 to commemorate the U.S. Civil War, now stands on the site of the Treaty in Penn Square.

In 1722, Virginia Lt. Governor Alexander Spotswood had arranged the Treaty of Albany with the (then) Five Nations. That treaty renewed the Covenant Chain and agreed to recognize the Blue Ridge Mountains as the demarcation between the Virginia Colony and the Five Nations (who that same year became known as the "Six Nations" with the addition of the Tuscarora).

Colonial governments were unable to prevent white settlers from moving beyond the Blue Ridge and into the Shenandoah Valley in the 1730s. When the Haudenosaunee Confederacy objected, they were told that the agreed demarcation was to prevent their trespassing east of the Blue Ridge, but not to prevent the English from expanding west of them. In 1743 the Iroquois skirmished with some Valley settlers. The Iroquois were on the verge of declaring total war on the Virginia Colony when Governor Gooch paid them the sum of 100 pounds sterling for any settled land in the Valley which they claimed. The following year, at the Treaty of Lancaster, the Iroquois sold all their remaining claim to the Shenandoah Valley for 200 pounds in gold. At the same time, it was an attempt to make peace between the Iroquois and the southern Catawba.

Even so, a difference in interpretation remained. The Virginians believed that the Haudenosaunee Confederacy had relinquished to the Crown any claim they had on all the lands within the 1609 Chartered boundaries of Virginia. They considered these boundaries to extend to the Pacific, or at least up to the Ohio River. The Iroquois understood that they had ceded only their lands up to the Ohio watershed; in other words, only the Shenandoah Valley east of the Allegheny Mountains.
