C.S. Lewis’s Narnia novel Prince Caspian was published in 1951.
Prince Caspian was the second Narnia book published, following The Lion, the Witch and the Wardrobe in 1950. Its full title is Prince Caspian: The Return to Narnia. The story returns Peter, Susan, Edmund, and Lucy to Narnia, where centuries have passed according to Narnian time.
The children find that the old Narnian world has been suppressed by the Telmarines. Prince Caspian, the rightful heir, is fighting to restore the traditions and creatures of earlier Narnia. The plot therefore combines a return journey with a political struggle over succession and cultural memory.
The title character is sometimes confused with King Caspian X, who appears in later Narnia stories. Prince Caspian becomes King Caspian after taking the throne, and he remains important in The Voyage of the Dawn Treader and The Silver Chair. The novel’s 1951 publication date places it immediately after Lewis’s first published Narnia volume.
