Eastern United States

The eastern United States, commonly referred to as the American East, Eastern America, or simply the East, is the region of the United States lying to the east of the Mississippi River.[1][2] In some cases the term may refer to a smaller area.[3]

The area ceded to the United States by Great Britain in 1783 (light brown) is usually recognized as the Eastern United States. Louisiana and Florida acquisitions were recognized as the Western and Southern frontiers in the early days of the Republic. Although east of the Rockies, Texas is frequently considered a Western state.
