Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
Historical reenactment (or re-enactment) is an educational or entertainment activity in which mainly amateur hobbyists and history enthusiasts dress in historic uniforms or costumes 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.
While historical reenactors are generally amateurs, some participants are members of armed forces or historians. The participants, called reenactors, often do research on 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 the Roman empire to the major world wars and the Korean War of the 20th century.
