Connect

Atlantic Coast: The eastern shoreline of the United States bordering the Atlantic Ocean. The region is defined partly by its position along this coast.
Northeast megalopolis: A continuous urban corridor extending from the Boston area through New York, Philadelphia, and Baltimore to Washington, D.C. It concentrates the region’s largest cities and connects them into one urban system.
Southern United States: The U.S. region associated with the states that formed the Confederacy and their neighboring states. The Mid-Atlantic’s southern boundary is often drawn against the South, though the transition is gradual.
American Revolution: The conflict from 1775 to 1783 in which the Thirteen Colonies won independence from Great Britain. Several Mid-Atlantic colonies became central settings for the Revolution and its founding politics.
Northeastern United States: A broad U.S. region that includes New England and states farther south along the Atlantic coast. The Mid-Atlantic is often treated as the southern portion of the Northeast.
New York metropolitan area: The metropolitan region centered on New York City and spanning parts of New York, New Jersey, and Connecticut. It is the Mid-Atlantic’s largest metropolitan center and crosses state lines.
Midwestern United States: A U.S. region centered on the Great Lakes and the interior plains west of the Appalachian Mountains. Pennsylvania’s inclusion can blur distinctions between Atlantic and interior regional identities.
Ellis Island: An island in New York Harbor that served as a major U.S. immigration station from 1892 to 1954. Its history reflects the migration that reshaped the region’s largest cities.
New England: A northeastern U.S. region comprising Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut. It borders the Mid-Atlantic’s northern edge but has a distinct regional identity.
Philadelphia metropolitan area: The urban region centered on Philadelphia and extending into southeastern Pennsylvania, New Jersey, and Delaware. It links the region’s central city with surrounding states and suburbs.
