USA250 was established in Philadelphia in 2011 to promote federal support for the United States Semiquincentennial. The organization also sought to position Philadelphia as a host city for anniversary events.
Philadelphia has a central place in the story of American independence: the Second Continental Congress met there, the Declaration of Independence was adopted there, and Independence Hall remains one of the best-known sites associated with the founding era.
USA250’s early advocacy preceded the federal commission created by Congress in 2016. That distinction is important because the names are easy to conflate. USA250 was an earlier Philadelphia nonprofit effort, while the United States Semiquincentennial Commission was the later congressional planning body.
The term America250 is also broader than the name USA250. America250 became the public-facing identity associated with the nationwide celebration, while Philadelphia-based groups continued developing local anniversary plans.
