Final answer:
The Iroquois, known for their participation in the "Mourning Wars" and their complex political systems, were one of the Native American tribes inhabiting the Northeastern Woodlands region.
Step-by-step explanation:
One Native American tribe that lived in the Northeastern Woodlands region was the Iroquois. This tribe was part of a larger confederacy which also included nations like the Oneida and Seneca.
The Iroquois were known for their unique political system and their role in warfare, particularly the "Mourning Wars," which were a significant aspect of their quest for power and revenge.
They, along with other tribes such as the Mohegan, Pequot, Narragansett, Patuxet, Wampanoag, Nipmuck, and Pennacook, were adept at both agriculture and hunting, forming societies with complex social structures, beliefs in land communal sharing, and strong leadership led by sachems and councils.
