Any benefits to having the English as allies and buffers proved short-lived. The Maryland Colony was initially too weak to pose a significant threat. But the Seneca continued to occasionally invade southward. Moreover, as the English persisted and eventually developed a more successful colony after resolving their own religious disputes, they turned against the Piscataway, competing for land and resources. Furthermore, some Piscataway had settled across the Potomac river, and became known as the Mattaponi. They became embroiled in the Anglo-Powhatan Wars.
