Caspian is a given name most famously used by author C. S. Lewis for a character in his Chronicles of Narnia series, first appearing in the 1951 book Prince Caspian. In the story, Prince Caspian is the rightful king of Narnia driven into exile by his evil uncle Miraz. Lewis likely derived the name from the Caspian Sea, the world's largest inland body of water, located between Europe and Asia. The sea's name itself originates from the ancient Cas tribe, known to the Greeks as the Caspii, who lived on its southwestern shores. The name ultimately comes from the city of Qazvin (historically Casbin) in modern Iran, and its ultimate origin is obscure.EtymologyLinguistically, Caspian is a Latin-derived adjective (from Caspius + -ian) meaning "of or pertaining to the Caspian Sea." Historically, the Caspians (Latin: Caspii) were an ancient people who inhabited the region known as Caspiane along the southern and southwestern shores of the sea. The ethnonym appears in Greek and Roman sources, notably in the works of Herodotus and Strabo. The connection to the sea became established already in antiquity: the Latin Caspium mare and Greek Kaspía thálassaLiterary SignificanceIn modern times, the name was elevated from a geographical label to a given name by C. S. Lewis, over and against the more common place-name origins of classic first names. Prince Caspian is a central figure in the Chronicles of Narnia and serves as a role model for courage and integrity among children. Since the series' publication, the name has been adopted quietly among readers, though it peaked in popularity in English-speaking countries in the early 2000s, concurrent with the films based on the Narnia books. The word has also been used in the formation of other historical terms, notably Hedwige a line of Frankish kings—which is a separate meaning from the present name.UsageWhile solely originating in literature, associated with character or regional connotations have enriched this Eurasian name's modern usage primarily in literature references for boys, often modeled after royalty.
