About LEGO Duplo

The LEGO DUPLO theme was introduced as far back as 1969 and is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick. Like LEGO System, DUPLO also has subthemes that are often junior versions of System themes, like Pirates and Castle and licensed themes like Disney and Super Heros.
1984 LEGO Sets
1984 cemented Castle’s identity with the debut of two enduring factions—the lion-badged Crusaders and the Black Falcons—bringing rival heraldry, fortified keeps, and standardized knight equipment. Space and Town sustained broad annual waves, and Trains added accessories that improved 12V layouts and operations.
