Historical term
Before 19th century westward expansion, the "Northern United States" corresponded to the present day New England region. By the 1830s it corresponded to the present day Northeastern United States
American Civil War
During the American Civil War, the Northern United States was composed of the U.S. states that remained in the United States of America, the Union states. In this context, "The North" is synonymous with the Union. In this context, "The South" is composed of the states that seceded from the U.S. to form the Confederate States of America.
However, which states comprised "The North" in this context can be the subject of historical disagreement. Some slave-holding states that remained in the Union, including Maryland below the Masonâ€"Dixon line, may be excluded. Some of the Union states were not geographically located in the north, but may be included.
