Tauxenent was the main town of the Moyumpse, also known as the Dogue

When John Smith sailed up the Potomac River in 1608, he encountered an Algonquian-speaking tribe at the mouth of the Occoquan River. Smith recorded 40 men capable of serving as warriors at their main town called Tauxenent. In contrast, he thought the Patawomeke had 160 "able men," the Moyowances had 100, and the Nacotchtanke had 80.1
The ancestors of those tribes had settled at the mouths of streams flowing into the Potomac River perhaps 500 years earlier, after adopting the pattern of growing corn for a large percentage of their diet. The original campsites of the first Native Americans in the area 15,000 years ago were underwater. They were drowned as the ice sheet melted, sea level rose, and the Chesapeake Bay formed.
After the Native Americans began relying upon corn around 900CE (Common Era), towns were created where estuaries provided food and soil was suitable for agriculture. The original settlers at the mouth of the Occoquan River may have abandoned that location, or may have been displaced, about 50 years before the English settled Jamestown. A new group may have migrated into the area between Quantico and Mason Neck in the middle of the 1500's.

The people Smith knew as the Taux (Tauxenant) may have called themselves the Moyumpse. Their rivals to the south, such as the Patawomeke, used the pejorative term "Dogue" to refer to the Moyumpse. Since the English associated most closely with the tribes controlled by Powhatan, by 1660 "Dogue" was the standard name among the colonists.2

West of the Fall Line, closer to the Blue Ridge, the Mannahoacks and Monacans were Siouian-speaking nations. The language diference, if correctly recorded by John Smith and others, suggest that two separate cultures occupied what is now Northern Virginia when Europeans arrived.

There is little historical evidence of interactions between those two cultures. Hunters must have encountered each other in the woods near what today are are Manassas and Leesburg. Moyumpse/Dogue would have had easier access to shells from the Chesapeake Bay and seafood from the Tidewater rivers. In planned meetings or in accidental encounters, people from two cultures may have negotiated to exchange dried fish and shell ornaments for rhyolite and jasper stone cores from the Blue Ridge.

In 1666, the Piscataway had been weakened greatly by raids from the Iroquois. To gain protection provided by the Maryland colonists, the tayac of the Piscataway signed "Articles of Peace and Amity" in the name of 11 other tribes, including the "Doags."3
