In 1950 C. S. Lewis, a Christian apologist, published The Lion, the Witch and the Wardrobe, the first of seven children’s fantasy novels in The Chronicles of Narnia (1950–1956).
The story follows four English children, evacuated to an old country house during wartime, as they pass through a magic wardrobe to visit Narnia, a land of talking animals and mythical creatures ruled by the evil White Witch.
Because the character Aslan, appearing in all seven books of the series, is widely accepted as based on Jesus Christ, The Chronicles of Narnia developed a large Christian following (although some objected to recurrent themes of paganism and occultism).
