CESAREVICH (better TsESAREV1cH), the title until 1917 of the heir-apparent to the Russian throne. The full official title was Nasliednik Tsarevich; i.e., "heir of Caesar," and in Russian the heir to the throne was commonly called simply Nasliednik, the word Tsarevich never being used alone. Tsarevich means any son of the emperor. The Cesarewitch handicap race at Newmarket, founded in 1839, was named after the prince, afterwards Alex ander II. of Russia, who paid a state visit to England that year.
