Which Narnia novel introduced readers to the land of Narnia?

The Lion, the Witch and the Wardrobe introduced readers to Narnia in C.S. Lewis’s series.

Published in 1950, the novel follows the Pevensie children—Peter, Susan, Edmund, and Lucy—after Lucy discovers a passage into another world through a wardrobe. There they encounter the faun Mr. Tumnus, the White Witch, and Aslan, the lion associated with Narnia’s restoration. The story combines wartime displacement, fantasy adventure, and Christian symbolism.

The book is the first published Narnia novel, although some modern editions arrange the series according to internal chronology and place The Magician’s Nephew first. That ordering can cause confusion when readers ask which book originally introduced Narnia. The wardrobe itself is a gateway rather than the name of the world, and Narnia is the country and wider setting in which the main adventure unfolds.
