query: What are Calormene social and political institutions like in The Horse and His Boy and The Last Battle?
answer: Calormene social and political institutions, as depicted in *The Horse and His Boy* and *The Last Battle*, remained essentially unchanged over more than a thousand years.  The ruler is the Tisroc, believed to be descended from the god Tash.  Society is rigidly hierarchical, with nobles (Tarkaan and Tarkheena), soldiers, merchants, peasants, and slaves.  Power and wealth determine social standing.  Honor and precedent are highly valued, and slavery is commonplace.
