As the United States prepares to mark its 250th anniversary this year, the Pennsylvania Historical & Museum Commission (PHMC) last week unveiled “Pennsylvania 250: The Keystone of American History,” a statewide, year-long initiative showcasing Pennsylvania’s central role in the nation’s founding, growth, and democratic evolution. The initiative brings together exhibitions, public programs, and major commemorations across PHMC museums and historic sites — from Harrisburg to Erie — under a unifying theme of democracy, innovation, and resilience.
