The Tisroc

The Tisroc is the title of the Calormene Emperor, and is believed to be descended from the Calormen god Tash. Whenever a Calormen citizen speaks of the Tisroc, he adds "may he live for ever," and it is considered blasphemy not to say this. The title prince is seemingly reserved for the heir apparent of the throne, and the Tarkaan nobles appear to be related to the Tisroc. It is implied that the Tisroc has many wives. The history of the Tisrocs is uncertain, developing from a strange surge of culture of an unknown period. It has been suggested that this culture came from Earth, an unmentioned human confrontation that merged with the original humans of Calormen, "certain" outlaws from Archenland.

Though the entire history of Calormen and the tisrocs are unknown a few tisrocs are mentioned in The Horse and His Boy:

Ardeeb Tisroc (ruled late 800's to c.900?- early to mid 900's)

Illsombreh Tisroc (ruled 900's)

Name Unknown (likely grandfather of Rabadash) ''(ruled mid to late 900's- c.1000)

"The Tisroc" (ruled c.1000- c.1030)

Rabadash the Ridiculous (rule uncertain, after c.1030?)

All the ruling dates mentioned are speculation, based off the known fact that "The Tisroc" began his rule around the year 1000, since his Grand Vizer Ahoshta claims that he began his rule at the end of the Age of Winter.
