Atropatene

Atropatene (Old Persian: Ātṛpātakāna; Ancient Greek: Ἀτροπατηνή), also known as Media Atropatene, was an ancient kingdom established in c.323 BC by the Persian satrap Atropates. The kingdom, centered in present-day northern Iran, was ruled by Atropates' descendants until the early 1st-century AD, when the Parthian Arsacid dynasty supplanted them.[2] It was conquered by the Sasanians in 226, and turned into a province governed by a marzban ("margrave").[3] Atropatene was the only Iranian region to remain under Zoroastrian authority from the Achaemenids to the Arab conquest without any interruption, aside from being briefly ruled by the Macedonian king Alexander the Great (r. 336–323 BC).
