Arlington County was part of the original ten-mile square created as the District of Columbia in 1791 pursuant to Article I, Section 17, of the United States Constitution. The portion of the District created from territory ceded by Virginia was termed Alexandria County of the District of Columbia. It included the present Arlington County plus part of what is now the independent city of Alexandria, Virginia. The area was returned to Virginia by an act of the United States Congress on July 9, 1846 following a referendum of its citizens. In 1870, Alexandria seceded from Alexandria County, and because of the confusion between the city and the county having the same name, a movement started to rename Alexandria County. In 1920, the name Arlington County was adopted, after Arlington House, the home of the American Civil War general Robert E. Lee, which stands on the grounds of what is now Arlington National Cemetery.
