In ancient history, there were 3 main dynasties that controlled ancient Persia, a western name for the area that is modern Iran: Achaemenids, Parthians, and Sasanids. There was also a period when the Hellenistic Macedonian and Greek successors of Alexander the Great, known as Seleucids, ruled Persia.
Early mention of the area is from Assyria c. 835 B.C., when the Medes occupied the Zagros Mountains. The Medes gained control of an area extending from the Zagros Mountains to include Persis, Armenia, and eastern Anatolia. In 612, they captured the Assyrian city of Ninevah.
Here are the rulers of ancient Persia, by dynasty, based on Dynasties of the World, by John E. Morby; Oxford University Press, 2002.
