The Persian Empire is one of a series of imperial dynasties centered in Persia (modern–day Iran). The first of these was the Achaemenid Empire established by Cyrus the Great in 550 BC with the conquest of Median, Lydian and Babylonian empires . It covered much of the Ancient world when it was conquered by  Alexander the Great. Several later dynasties "claimed to be heirs of the Achaemenids". Persia was then ruled by the Parthian Empire which supplanted the Hellenistic Seleucid Empire, and then by the Sassanian Empire which ruled up until the mid-7th century. 
While many of these empires referred to themselves as Persian, they were often ruled by ethnic Medes, Babylonians, or Parthians. Iranian dynastic history was interrupted by the
Arab conquest of Persia in 651 AD, establishing the even larger Islamic caliphate, and later by the Mongol invasion.
The main religion of ancient Persia was the native
Zoroastrianism, but after the seventh century, it was replaced by Islam.
Safavid Empire was the first Persian empire established after Arab conquest of Persia by the Shah Ismail I. Safavids ruled Persia independently from the Arab and Ottoman Sunni caliphates by making Shia Islam Persia's official religion, who became Persia's classical rival, like the pagan Romans and Christian Byzantines had been before. Since 1979 and the downfall of the last Persian monarchy Pahlavi dynasty during the Iranian Revolution, Persia has had a Shia Islamic theocratic government named the Islamic Republic.
