Shawnee, Nanticoke, Conoy, and Tutelo were evicted by the terms of the 1768 Treaty of Fort Stanwix, which was between the Iroquois League and the British Crown. After 1768, hundreds of British, Irish, and German families flooded in from New England, New York, New Jersey, and Pennsylvania to occupy lands purchased from the Susquehanna and Connecticut Land companies of Connecticut. These settlements eventually led to armed conflict with the Penn proprietors (William Penn's sons, Richard and Thomas, and his grandson, John), who also claimed the land. (See Pennamite Wars). During the American Revolution in 1778, a combined British, Tory, Iroquois, Munsee, and Lenape force attacked the Wyoming Valley settlers on the eastern edge of this region, and killed many of the settlers. Washington sent Major General John Sullivan on a campaign to destroy the Iroquois threat by a "scorched earth" drive up the Susquehanna and Chemung Rivers into central and western New York. The region's economy was formerly based on mining, lumbering (especially of hemlock for tanning) and industry but is now largely agricultural with forestry and tourism contributing to the economic base. Much of the land is steep, but there are a few good farms on rolling hilltops or valley bottoms; many of these farms have been occupied by Mennonite and Amish people who have migrated northward as their traditional homelands became developed. Quarrying remains an important local industry with the region's high quality blue stone being particularly valuable. The area is on the edge of Pennsylvania's Coal Region, with some minor veins of coal extending into the area. Songwriter Stephen Foster lived in the area for a while, and Bradford County's Camptown is immortalized in his song "Camptown Races".
