Kaiszár

Kaiszár is the Ostergerican word for "emperor". Like the Bulgarian, Serbian, and Russian word Tsar, it is directly derived from the Roman emperors' title of Caesar, which in turn is derived from the personal name of the Julii Caesares, a branch of the gens (clan) Julia, to which Gaius Julius Caesar, the forebear of the Julio-Claudian dynasty, belonged. In general the Ostergerican title was only used for rulers over the rank of kings (König).

Although the British monarchs styled "Emperor of India" were also called Kaisar-i-Hind in Hindi and Urdu, this word, although ultimately sharing the same Latin origin, is derived from the Greek: Καῖσαρ (kaisar), not the German Kaiser.

In English, the term "the Kaiszár" is usually reserved for the emperor of the Isantine Empire or the emperor of the Ostercian-Ungyarian Empire. The title of "Kaiszár" has high historical respect in Ostergeric heartland regions.
