Teedyuscung (1700–1763) was known as King of the Delawares. He worked to establish a permanent Lenape (Delaware) home in eastern Pennsylvania in the Lehigh, Susquehanna and Delaware River valleys. Teedyuscung participated in the Treaty of Easton which resulted in the loss of any Lenape claims to all lands in Pennsylvania. Following the treaty the Lenape were forced to live under the control of the Iroquois in the Wyoming Valley near modern day Wilkes-Barre. Teedyuscung was murdered by arsonists on April 19, 1763 as he reportedly lay asleep as his cabin burned around him. This marked the beginning of the end of the Lenape presence in Pennsylvania. Teedyuscung's son Chief Bull conducted a raid on the Wyoming Valley that was part of a greater Indian uprising that resulted in the Lenape being forced to move west of the Appalachian Mountains by the Royal Proclamation of 1763
