Tsesarevich (, ) was the title of the heir apparent or presumptive in the Russian Empire. It either preceded or replaced the given name and patronymic.
Usage
It is often confused with the much more general term tsarevich, the title for any son of any tsar, including non-Russian rulers such as those of Crimea, Siberia, and Georgia.
Normally, there was only one tsesarevich at a time (an exception was Grand Duke Konstantin Pavlovich, who was accorded the title until death, even though law gave it to his nephew), and the title was used exclusively in Russia.
The title came to be used invariably in tandem with the formal style "Successor" (), as in "His Imperial Highness the Successor Tsesarevich and Grand Prince". The wife of the Tsesarevich was the tsesarevna ().
History
In 1721 Peter the Great discontinued use of "tsar" as his main title, and adopted that of imperator (emperor), whereupon the title of tsarevich (and "tsarevna", retained for life by Ivan V's daughters) fell into disuse.
