Emperor (Tsar)
The title of
Emperor has been in existence since Peter the Great abolished the appellation "
Tsar".
Unfortunately many insist using
Tsar incorrectly when refering to the Imperial Russian heads of State after and including Peter I.
Nikolai II was the
Imperator (Emperor) and
Samoderjetz (Autocrat) of all the Russias.
His consort was the
Tsaritsa or more officially she was refered to as the
ImperatritsaThe Emperor's son who was in line to the throne was refered to as the
Naslednik Tsesarevich (Heir apparent). If he married before suceeding his father, the wife was refered to as a
Tsesarevna.A son of an Emperor who was not an heir was titled as a
Velikii Knyaz' (Grand Duke), while a daughter was called a
Velikaya Knyaginya (Grand Duchess).
All the above titles apply to the immediate Imperial Family.
The Dowager Empress was refered to as:
Ee Vdovstvyushaya Imperatritsa and she formally preceeded the Emperor's consort.
