Overview

Washington, D.C., officially the District of Columbia, is the capital city of the United States. It was established by the Constitution of the United States to serve as the seat of the federal government. The city's creation was authorized by the Residence Act of 1790, which President George Washington signed into law. This act designated a 100-square-mile territory along the Potomac River as the permanent capital.

The district was formed from land donated by the states of Maryland and Virginia, though the Virginia portion was returned in 1847. Pierre Charles L'Enfant designed the city's original layout with wide avenues and ceremonial spaces. The city was officially founded on July 16, 1790, and named after George Washington and Christopher Columbus. Today, it serves as the political center of the United States and a symbol of American democracy.

It contains over 297 federal buildings and monuments, including the iconic Washington Monument at 555 feet tall. The federal government employs approximately 29% of the district's workforce.
