Caliphate The Arab—and then Muslim—Empire.

Chalcedonian Someone who subscribes to the doctrinal formulations of the Council of Chalcedon, held in 451. It is a measure of the triumph of the Chalcedonians over their various rivals in the Christian Church that they succeeded in appropriating the adjectives “Catholic” and “Orthodox.” Today’s Roman Catholic, Greek Orthodox and Protestant Churches are all Chalcedonian.

Zoroastrians regarded him as being, like Anahita, a lieutenant of Ohrmazd; but there were many, in the remoter reaches of Iranshahr, who worshipped him as a great god in his own right.
Mihran A Parthian aristocratic dynasty.
Minim A Hebrew word that the rabbis applied to heretics; sometimes used as shorthand for “Christians.”
