C.S. Lewis gives the world inside his wardrobe stories the name Narnia. Narnia is the central fictional realm of The Chronicles of Narnia, the seven-book series published between 1950 and 1956.
The world is created by the lion Aslan in The Magician’s Nephew, which was published sixth in the original publication sequence but is often read first in chronological order. The Lion, the Witch and the Wardrobe introduced many readers to Narnia in 1950.
Narnia contains talking animals, mythical creatures, kings and queens, and a distinct history spanning many centuries. Other lands in the series include Archenland, Calormen, and the land of Bism.
Narnia is sometimes used loosely for the entire setting, but the name properly identifies the central country or world around which the stories are organized. The wardrobe is a gateway to Narnia, not the name of the realm itself.
