Who were the Eastern Woodlands?

Eastern Woodland Indians were several tribes that lived east of the Mississippi. 

Woodland Indian tribes lived east of the Plains Indians.  They lived from Maryland to Lake Michigan. They lived in the forests near lakes or streams, which is why they're called Eastern Woodland Indians. Their food, shelter, clothing, weapons and tools came from the forest. The Iroquois, Mound Builders, Algonquian and Shawnee are a few Woodland tribes.
