Historical reenactment is an educational activity in which participants attempt to recreate some aspects of a historical event or period, such as The Battle of Hastings and The Crusades of the 11th, 12th and 13th century. It's a fascinating subject to photograph and the re-enactors are more than willing to let you take photographs of them.
