Historical reenactments (or re-enactment) is an educational or entertainment activity in which mainly amateur hobbyists and history enthusiasts dress in historical 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 a reenactment of Pickett's Charge presented during the 1913 Gettysburg reunion, or as broad as an entire period, such as Regency reenactment.
While historical reenactors are generally amateurs, some participants are military personnel or historians. The participants, called reenactors, often research the equipment, uniform, and other gear they will carry or use. Reenactors buy the apparel or items they need from specialty stores or make items themselves. Historical reenactments cover a wide span of history, from as far back as late antiquity, the post-classical era, and the early modern period, to as recent as the World Wars, the Cold War era, and even the early 21st century.
