Which C.S. Lewis novel introduced the world of Narnia in 1950?

The C.S. Lewis novel that introduced the world of Narnia in 1950 was The Lion, the Witch and the Wardrobe. It was the first Narnia book published and remains the series’ best-known entry point.

The story follows four siblings—Peter, Susan, Edmund, and Lucy Pevensie—who discover a magical land through a wardrobe. Narnia is under the rule of the White Witch, whose winter has lasted for a hundred years. The children meet Aslan and become involved in the struggle to restore Narnia.

The Narnia books can be read in publication order or in an internal chronological order. The Lion, the Witch and the Wardrobe was published first, while The Magician’s Nephew is set earliest in Narnian history. This distinction explains why lists sometimes place the books in different sequences.
