Washington was founded on July 16, 1790, when Congress approved a permanent national capital along the Potomac River. The location reflected a compromise between Northern and Southern states, linking a new federal city to an existing port town.
From its inception, the city was designed as a symbol of national unity and governance, combining planned avenues with riverfront access. Today, the founding date is remembered as the moment the District of Columbia officially became the seat of the United States government.

Planning and Survey of the Federal City
Choosing the Site
The decision to locate the national capital on the Potomac was driven by geographic centrality, navigation access, and political bargaining. Delegates from northern and southern states agreed that a Southern site would secure Southern support for federal assumption of Revolutionary War debts.
Laying Out the City
Pierre Charles L’Enfant designed the street grid and monumental axes, while Andrew Ellicott refined the plan and conducted boundary surveys. Their combined work established the street network and key landmarks, such as the Capitol and the President’s House.
Founding Events and Legislative Actions
Congressional Approval
The Residence Act of 1790 authorized the creation of a federal district along the Potomac, specifying that the president would select the exact location within a defined window of time. This law provided the legal foundation for Washington’s establishment.
Land Donation and Transfer
Maryland and Virginia ceded land to the federal government, creating the initial district of approximately 100 square miles. Property owners later lobbied for compensation, highlighting the financial dimensions of the founding process.

Political Context and Regional Impact
Northern-Southern Compromise
Southerners wanted a capital closer to their agricultural and economic interests, while Northerners pushed for a site more aligned with commercial centers. The compromise balanced these interests by placing the capital in a Southern location tied to existing trade routes.
Economic Consequences
The creation of the federal district stimulated local land values and construction, especially for housing, government offices, and infrastructure. Enslaved labor and free labor combined to build the physical foundations of the new city, shaping its early demographics.
