The Algonquian-speaking Piscataway people inhabited present-day Washington, D.C. and lands around the Potomac River when Europeans first arrived and colonized the region in the early 17th century. The Nacotchtank, also called the Nacostines by Catholic missionaries, maintained settlements around the Anacostia River in present-day Washington, D.C. Conflicts with European colonists and neighboring tribes ultimately displaced the Piscataway people, some of whom established a new settlement in 1699 near Point of Rocks, Maryland.
