Throughout much of early history, the land known today as Iran was known as the Persian Empire. The first great dynasty in Iran was the Achaemenid which ruled from 550 to 330 BC. It was founded by Cyrus the Great. This period was followed by the conquest of Alexander the Great from Greece and the Hellenistic period. In the wake of Alexander's conquests, the Parthian dynasty ruled for nearly 500 years followed by the Sassanian dynasty until 661 AD.
In the 7th century, the Arabs conquered Iran and introduced the people to Islam. More invasions came, first from the Turks and later from the Mongols. Starting in the early 1500s local dynasties once again took power including the Afsharid, the Zand, the Qajar, and the Pahlavi.
