Washington, D.C.

• Type: City, Former MACUSA Capital
• Location: United States of America
• Owner/Residents: MACUSA (formerly)
• Key Features: Served as the fourth historical headquarters for the wizarding government of the United States of America.

Washington, D.C. is the capital city of the No-Maj (Muggle) United States of America. Within the magical world, it is historically significant for having been the fourth home of the Magical Congress of the United States of America (MACUSA). In 1760, MACUSA relocated its headquarters from Baltimore, Maryland, to Washington. This move occurred during a period of significant debate and tension within the American wizarding community regarding their level of integration with the No-Maj population. The wizarding government remained in Washington for a period before making its fifth and final move to the Woolworth Building in New York City, where it is currently located. The exact location of the MACUSA headquarters within Washington, D.C. is unknown (Pottermore).

Washington, D.C. is not mentioned in the original seven Harry Potter novels. Its significance is established in supplementary materials concerning the history of magic in North America. The city's role as a former seat of magical power underscores the long and established history of a structured wizarding society in the United States of America, with its government often situated in or near prominent No-Maj centers of power. It serves as a historical footnote in the evolution and development of MACUSA as the primary governing body for American witches and wizards.

There are no specific magical locations, buildings, or districts within Washington, D.C. that are described in the canon. The precise location and nature of the MACUSA headquarters during its time in the city have not been revealed.

• The information that MACUSA was based in Washington comes from J.K. Rowling's writings on the Pottermore (now Wizarding World) website, specifically in the collection titled A History of Magic in North America.
• There is a minor historical discrepancy in the timeline provided. The source material states that MACUSA moved to Washington in 1760. However, the No-Maj city of Washington, D.C. was not founded until 1791, following the Residence Act of 1790. This may suggest that the wizarding community established a presence in the area that would become the nation's capital before it was officially founded by No-Majs.
