Which C.S. Lewis novel introduced readers to the land of Narnia in 1950?

The Lion, the Witch and the Wardrobe introduced readers to the land of Narnia in 1950.

The novel follows the Pevensie siblings—Peter, Susan, Edmund, and Lucy—after Lucy discovers a magical passage through a wardrobe. Beyond it lies Narnia, a world trapped in winter under the rule of the White Witch. The children become involved in a conflict linked to the return of Aslan and the restoration of Narnia.

The book was the first published volume in Lewis’s Chronicles of Narnia, although internal chronological lists sometimes place The Magician’s Nephew first. That difference between publication order and story chronology causes frequent confusion.

The novel combines Christian symbolism, classical mythology, talking animals, adventure, and fairy-tale motifs. Its publication established the setting and major themes that Lewis continued across six subsequent Narnia books.
