The area now known as Duryea Borough was historically the heartland of the Susquehannock tribe, also called the Conestoga, which were an Iroquoian people whose territory extended from lower New York State to the Potomac. The Susquehannock befriended the Dutch traders by 1612, who soon began trading tools and firearms for furs. The Dutch had established their trading posts along the rivers near where two natural Indian trails allowed them to make contact with the Conestoga— these were the sometimes disputed lands of the Susquehannocks and the rival Delaware nation (Lenape people).
