If you’ve ever visited a historic site or museum around the time of a major anniversary, you’ve probably encountered a historical reenactor. Maybe you were at Fort George in Niagara-on-the-Lake, or Gettysburg, Pennsylvania, or at a D-Day commemoration on 6 June, or any number of hundreds of different re-enactments big and small that take place every year. These historical reenactors share a love of history with historians, though they have vastly different views of it.
