Mummers' plays are folk plays performed by troupes of amateur actors, traditionally all male, known as mummers or guisers (also by local names such as rhymers, pace-eggers, soulers, tipteerers, wrenboys, and galoshins). Historically, mummers' plays consisted of informal groups of costumed community members that visited from house to house on various holidays. The modern term refers especially to a play in which a number of characters are called on stage, two of whom engage in a combat, the loser being revived by a doctor character. This play is sometimes found associated with a sword dance though both also exist in Britain independently.
Plays may be performed in the street or during visits to houses and pubs. They are generally performed seasonally, often at Christmas, Easter or on Plough Monday, more rarely on Halloween or All Souls' Day, and often with a collection of money. The practice may be compared with other customs such as those of Halloween, Bonfire Night, wassailing, pace egging and first-footing at new year.
