Which series by C.S. Lewis contains seven books set largely in Narnia?

The Chronicles of Narnia is C.S. Lewis's seven-book series set largely in Narnia.

The series begins with The Lion, the Witch and the Wardrobe in its traditional publication order and concludes with The Last Battle. Its stories combine talking animals, invented history, children from Earth, mythical creatures, and Christian symbolism. Aslan, the great lion, is the central recurring figure and the ruler of Narnia.

The books were published between 1950 and 1956. The publication order differs from the internal chronological order sometimes used in modern editions. The Magician’s Nephew, for example, was published sixth but describes events before the story of The Lion, the Witch and the Wardrobe.

Narnia is not the name of the series itself; it is the fictional world at the center of the books. Lewis also wrote science fiction and literary criticism, but those works do not belong to The Chronicles of Narnia.
