The Reconstruction Era National Historical Park, formerly Reconstruction Era National Monument, is a United States National Historical Park in Beaufort County, South Carolina established by President Barack Obama in January 2017 to preserve and commemorate activities during the Reconstruction Era that followed the American Civil War. The monument was the first U.S. National Monument dedicated to the Reconstruction Era. The John D. Dingell, Jr. Conservation, Management, and Recreation Act, signed March 12, 2019, by President Donald Trump, re-designated it as a national historical park.
