The Northeastern United States consists of the states Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont. The region has an area of 181,324 square miles, 162,257 of which is land. The region is America's most economically developed, densely populated, and culturally diverse, as well as its second most urban, with 85% of its population living in urban areas. The area is divided into two sub-regions: New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont), and the Mid-Atlantic (New Jersey, New York, and Pennsylvania).

The smallest region in the United States, the Northeast is home to the easternmost point in the United States, West Quoddy Head in Maine. The Appalachian Mountains run through the region, with the windy 6,288-foot Mount Washington (New Hampshire) being the tallest. The Hudson, Delaware, and Ohio are some of the major Northeastern rivers.

History of New England
At the time of the arrival of the Pilgrims from England in 1620, the area of New England and the Mid-Atlantic were known as the Northeastern Woodlands, which also covered much of Canada and other land in the eastern United States. Many tribes inhabited the area, many of which made up the Iroquois Nations, or were Algonquian peoples. Ten years after the Pilgrims arrived, a larger group of Puritans settled in Boston to form the Massachusetts Bay Colony.  In 1636, colonists established the Connecticut Colony and the Providence Plantations, the first settlement in modern day Rhode Island. Roger Williams, who was banished by Massachusetts for believing in freedom of religion, founded Providence, the first colony to guarantee all citizens freedom of religion. The nearby Portsmouth was founded by Anne Hutchinson, who also was banished from Massachusetts. Providence and Portsmouth, along with the towns of Newport and Warwick, joined together to form the Colony of Rhode Island and Providence Plantations. All of the states in New England were one of the thirteen original colonies (Maine and Vermont were part of other colonies before they became independent), and the region, especially Boston, was a center of revolutionary activity in the 1760s and 1770s. American patriots like Samuel Adams, John Hancock, and John Adams, all resided in New England. On December 16, 1773, the Boston Tea Party, a significant event in the American Revolution, occurred, and 17 months later, the first battles of the Revolutionary War, the Battles of Lexington and Concord, happened around twenty miles from Boston. Throughout the 1800s, New England was the most urban region of the country, home to 32 of America's 100 most populous cities in 1860. New England produced many notable literary and intellectual figures in the Antebellum period, including Nathaniel Hawthorne, Ralph Waldo Emerson, Henry David Thoreau, Henry Wadsworth Longfellow, and William H. Prescott. New England became an early center of the industrial revolution, with its many textile and cotton mills creating thousands of jobs. However, after World War II, these factories were practically all gone, with most of the mills going out of business one by one from the 1920s to the 1970s. The region today is well known today for its technology industry, as well as its education, research, and finance.

History of the Mid-Atlantic
Henry Hudson first explored the area of New York in 1609 and claimed it for the Netherlands. Many Dutch settlers followed, and the area became known as New Netherland, with the capital of this province named New Amsterdam (present-day New York). In 1664, England annexed New Netherland, and this area became the colonies of New York and New Jersey. In 1681, Pennsylvania was founded by William Penn, who wanted to give Quakers a land of religious freedom. The region served as a bridge between the North and South, and by the 1700s, it was home to two of the largest cities in the colonies: Philadelphia and New York City. Philadelphia was home to the Continental Congress, which organized the American Revolution. In 1776, the Declaration of Independence was drafted there, as well as the United States Constitution in 1787. Heavy industry spread throughout the region, with the Delaware Rivers and Hudson Rivers providing transportation for goods. Because of Philadelphia's location along the Delaware and New York City's location along the Hudson, both cities grew dramatically. Similar to New England, its heavy industry has mostly disappeared, with New York and Philadelphia as two of the nation's premier financial centers and service, insurance, and healthcare also as large parts of the economy.

Massachusetts is home to the first public school in the English colonies, Boston Latin School, which was founded in 1635, as well as the first institution of higher education in the United States, Harvard College, which was founded one year later in 1636. The Northeast region is home to all 8 of the prestigious Ivy League schools- Harvard University (Cambridge, Massachusetts), Yale University (New Haven, Connecticut), Princeton University (Princeton, New Jersey), Brown University (Providence, Rhode Island), Dartmouth University (Hanover, New Hampshire), Cornell University (Ithaca, New York), Columbia University (New York, New York), and University of Pennsylvania (Philadelphia, Pennsylvania). Other colleges in the Northeast which are among the nations finest include Massachusetts Institute of Technology, Carnegie Mellon University, Tufts University, Boston College, and New York University.

Culture and Politics
The Northeast, especially New England, is famous for its seafood. Maine's lobster is among the most sought after in the country, Boston is famous for its clam chowder, and the entire region is well-known for its fried and steamed clams. While the region was previously dominantly Republican, it has been extremely liberal since the late twentieth century. In the past six elections, the entire region has voted for the democratic candidate, with the exception of 2000, where New Hampshire voted for George W. Bush. While in most other regions, Protestants outnumber Catholics, Catholics outnumber Protestants in five out of the Northeast's nine states (Massachusetts, Rhode Island, Connecticut, New York, and New Jersey), the only five states in the nation where this happens. The Northeast is also home to a large population of Jews, Hindus, and Muslims. The Northeast is a very ethnically diverse region, with the largest concentration of Italian-Americans and Irish-Americans in the country, as well as high numbers of African-Americans, Hispanics, and Asians.

The Northeast is home to 22 teams from the MLB, NBA, NFL, and NHL. 

Boston (4): Boston Red Sox (MLB), Boston Celtics (NBA), New England Patriots (NFL), Boston Bruins (NHL)
New York City (8) and New Jersey (1): New York Yankees (MLB), New York Mets (MLB), New York Knicks (NBA), Brooklyn Nets (NBA), New York Giants (NFL), New York Jets (NFL), New York Islanders (NHL), New York Rangers (NHL), New Jersey Devils (NHL)
