DC flag

The DC flag is based on George Washington's family coat of arms — two horizontal red stripes and three red stars on a white field. Adopted in 1938, it has become a potent symbol of statehood advocacy.

  • Three Red Stars — represent the three commissioners who originally governed the District, and echo the Washington family crest.
  • Two Red Stripes — also derived from the Washington coat of arms; the bars symbolize heritage and continuity.
  • White Field — represents purity and the city's aspirations as the capital of democracy.

Overview

Washington D.C. is unlike any other place in the United States — a planned federal city that is simultaneously the world's most powerful address and an open museum of American democracy. Carved from land ceded by Maryland and Virginia in 1790, it was designed by Pierre Charles L'Enfant on a grand diamond grid of diagonal avenues and ceremonial circles. Today it is a city of monuments and embassies, of marble corridors and vibrant neighborhoods, home to 712,000 residents who live at the center of institutions that shape the entire world.

Geographically, it shares borders with Maryland and Virginia, forming a closely connected regional network.

Historical Significance

The District was formally established on July 16, 1790 by the Residence Act, with George Washington personally selecting the site along the Potomac River. By 1800, Congress and President Adams had relocated from Philadelphia. The city was burned by British forces in 1814, rebuilt, and became the stage for the nation's most consequential moments — Lincoln's Second Inaugural, FDR's New Deal, the 1963 March on Washington where Dr. King delivered "I Have a Dream," and 57 Presidential Inaugurations held on the Capitol's East Front.
