Which organization, established in 2016, organized the United States Semiquincentennial?

The United States Semiquincentennial Commission, established in 2016, organized the national 250th-anniversary commemoration.

The commission was created as a congressional, nonpartisan body to help plan and coordinate programs marking the 250th anniversary of the Declaration of Independence. America250 is the public-facing name associated with the wider initiative and its supporting organization.

This commission is distinct from the American Revolution Bicentennial Commission, which was created in 1966 for the 200th-anniversary observance held in 1976. The two celebrations were separated by half a century and used different coordinating structures.

The commission’s work spans national programs, partnerships, educational activities, and participation by states and territories. Its purpose is broader than staging one ceremony: it supports a nationwide commemoration of the founding era and the country’s continuing civic story.
