History Brief: Chesapeake Bay explorer John Smith was the first European to meet the Susquehannocks in 1608. Smith described them as giants! Interestingly enough, they had only arrived in the Susquehanna Valley 50 years prior but soon became active fur traders with the Europeans. Through genocide and disease, the Susquehanna saw their numbers plummet until there were only 20. Eventually, they became known as the Conestoga, and in 1763, a group of vigilantes known as the Paxton Boys massacred what remained of the tribe. The Susquehannock as a people and their language are considered extinct.
