The Northeastern United States is the nation's most economically developed, culturally diverse and densely populated region. The variety of elevations and geography in this region make for differing climates across this area, but the woodlands of the Northeast were especially populated by Native Americans throughout history.
- Almost half of the National Historic Landmarks in the U.S. are located within the northeastern states.
- This region is home to Eastern Woodland Indians, who were known for building longhouses, a building style very emblematic of Eastern Native American culture.
- Six tribes make up the Iroquois Federation in present-day New York, and their confederacy is said to have influenced America's founding fathers while writing the Constitution and the Bill of Rights.
