Medieval theatre developed from 5th-16th century and included religious plays like mysteries about biblical stories, miracles about saints' lives, and moralities with allegorical themes. These were typically performed by trade guilds and clergy to teach illiterate audiences. Secular plays also emerged like interludes for courtly entertainment and folk plays incorporating pagan traditions. Dramatic techniques included processional wagons, allegorical characters, and special effects. Theatre was an integral part of medieval culture and education.
