CESAREVICH  , or more properly TSESAREVICH, the

title of the heir-apparent to the Russian throne . The full official title is Nasliednik Tsesarevich, i.e . " heir of Caesar," and in Russia the heir to the throne is commonly called simply Nasliednik, the word Tsesarevich never being used alone . Tsarevich, a form now much used in England, means simply any " king's son "; it is an antiquated term now out of use in Russia, and was last borne as heir to the throne by the unfortunate Alexius, son of Peter the Great . The style of the wife of the tsesarevich is Tsesarevna . The Cesarewitch handicap race at Newmarket, founded in 1839, was named after the prince who was afterwards Alexander II. of Russia, who paid a state visit to England that year .
