C.S. Lewis created the fictional land of Narnia in The Chronicles of Narnia.
Narnia is the central setting of Lewis’s seven-book fantasy series, beginning with The Lion, the Witch and the Wardrobe and concluding with The Last Battle. The world contains talking animals, mythical creatures, human visitors, and the great lion Aslan.
The series was published between 1950 and 1956, although its internal chronology begins with The Magician’s Nephew. Lewis uses Narnia to explore themes including courage, temptation, sacrifice, forgiveness, and the relationship between ordinary children and a larger moral world.
Narnia is not the same setting as Middle-earth, which was created by J.R.R. Tolkien, or Earthsea, which was created by Ursula K. Le Guin. Those comparisons can cause confusion because all three are major fantasy settings.
