Historical reenactment (or re-enactment) is an educational or entertainment activity in which mainly amateur hobbyists and history enthusiasts put on uniforms and follow a plan to recreate aspects of a historical event or period. This may be as narrow as a specific moment from a battle, such as the reenactment of Pickett's Charge presented during the Great Reunion of 1913, or as broad as an entire period, such as Regency reenactment.
