History
The area was inhabited by indigenous groups including the Nacotchtank prior to European contact and was explored by Captain John Smith during the early British colonization of the Americas. The Residence Act of 1790 authorized a federal seat; George Washington selected the site, and Pierre Charles L'Enfant designed the initial plan. The district was formed from land ceded by Maryland and Virginia; the portion ceded by Virginia was retroceded in 1846 through legislation influenced by representatives such as John C. Calhoun. During the War of 1812 British forces occupied and burned key buildings, including the United States Capitol and the White House. The district's governance evolved with acts by the United States Congress, including the Organic Acts and the District of Columbia Home Rule Act, amid civil rights struggles led by figures like Martin Luther King Jr. and campaigns by activists such as Marian Anderson and organizations like the National Association for the Advancement of Colored People.
