The American Revolution has returned to Philadelphia. After almost two decades of planning and fund-raising, the Museum of the American Revolution opened its doors last April 19, the anniversary of the battles of Lexington and Concord. Its thousands of artifacts, with the support of the latest interactive digital technology, recount a provocative story of how ordinary men and women of different races and ethnicities experienced military conflict and then, having achieved independence from Great Britain, created a republic that has survived for more than two centuries.
