And the king of Pars was Cyrus the Great. And in 550, 549 BCE, he's able to overthrow the Median Emperor, who happens to be his grandfather. And then he establishes what history views as the first real Persian Empire. And the whole reason why we even call it a Persian Empire is because Cyrus the Great was from Pars. Persian is really referring to the idea that the ruler, the dynasty that gets established, was coming from Pars. It turns out, and I talk about it in other videos, the Persians did not refer to themselves as Persians. They viewed themselves more as the Aryan people.
