Which federal commission organized the United States Semiquincentennial known as America250?

The United States Semiquincentennial Commission organized the national 250th-anniversary effort known as America250.

Congress created the commission to plan and coordinate observances of the 250th anniversary of the founding of the United States. Its work included encouraging federal, state, local, and international activities connected with the milestone.

The commission is distinct from America250.org, Inc., the nonprofit supporting organization associated with the public-facing campaign. The commission is the congressional body, while America250 is the familiar branding used for the broader commemoration.

The commission’s responsibilities also included supporting commemorative coins and stamps, encouraging events in historically significant locations, and preparing recommendations for national observances. Its creation gave the anniversary a formal federal planning structure well before 2026.
