Tsarevitch

Tsesarevich (Russian: Цесаре́вич, IPA: [tsɨsɐˈrʲevʲɪtɕ]) was the title of the heir apparent or presumptive in the Russian Empire. It either preceded or replaced the given name and patronymic.

It is often confused with "tsarevich", which is a distinct word with a different meaning: Tsarevich was the title for any son of a tsar, including sons of non-Russian rulers accorded that title, e.g. Crimea, Siberia, Georgia. Normally, there was only one tsesarevich at a time (an exception was Grand Duke Constantine 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" (Naslednik), as in "His Imperial Highness the Successor Tsesarevich and Grand Duke". The wife of the Tsesarevich was the Tsesarevna.

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 desuetude. The Emperor's daughters were henceforth referred to as "tsesarevna" (Peter had no living son by this time). In 1762, upon succeeding to the imperial throne, Peter III accorded his only son Paul Petrovich (by the future Catherine the Great) the novel title of tsesarevich, he being the first of nine Romanov heirs who would bear it. However, at the time the title was conferred, Paul was recognized as Peter's legal son, but not as his legal heir. Nor would he be officially recognized as such by his mother after her usurpation of the throne.
