The Independence Hall Association (IHA) is a Philadelphia--based historical organization.
Founded in 1942, it was the driving force behind the creation of Independence National Historical Park in Philadelphia, Pennsylvania, which houses Independence Hall, the Liberty Bell, and other buildings and historical items associated with the American Revolution.
The Independence Hall Association was organized by Edwin O. Lewis, a former Common Pleas Court of Pennsylvania judge who at the time was president of the Pennsylvania Chapter of the Sons of the American Revolution.
