The Lion, The Witch and The Wardrobe was published in 1950, and it was the book that first introduced readers to the World of Narnia. Years later, in 1955, Lewis wrote a prequel to The Lion, the Witch and the Wardrobe, entitled The Magician's Nephew. While The Magician's Nephew was the sixth Narnia book to be written, many readers prefer to begin the series with The Magician's Nephew.
