224 - 651 CE
For over four centuries, the Sasanian Empire stood as the last great Persian empire of antiquity, rivaling Rome and later Byzantium as the most powerful state in the ancient world.
The Sasanian Empire, named after the ancestor Sasan, was founded in 224 CE when Ardashir I overthrew the last Parthian king Artabanus IV. The Sasanians saw themselves as the successors to the Achaemenid Empire of Cyrus and Darius, seeking to restore Persian glory and Zoroastrian orthodoxy.
At its height, the empire stretched from the Euphrates to the Indus, from the Caucasus to the Persian Gulf. The Sasanians developed a highly centralized bureaucratic state, a sophisticated legal system, and made lasting contributions to art, architecture, music, and philosophy that would influence the Islamic civilization that followed.
The empire was known for its constant rivalry with Rome and later Byzantium, fighting numerous wars over control of Mesopotamia, Armenia, and the trade routes of the ancient world. This rivalry only ended with the Arab conquests of the 7th century, which brought both empires to their knees.

Understanding the Empire
The Sasanians established Zoroastrianism as the state religion, with the Magi wielding significant political power. The Avesta was codified, and fire temples were built throughout the empire. Religious minorities including Christians, Jews, and Manichaeans had varying degrees of tolerance depending on the ruling monarch.
Sasanian art reached remarkable heights, particularly in rock reliefs, metalwork, and textiles. The palace at Ctesiphon with its famous Taq Kasra arch remains one of the largest single-span brick vaults ever constructed. Sasanian artistic motifs would profoundly influence Islamic and Byzantine art.
The Sasanian military was centered on heavy cavalry, the cataphracts (savaran), supported by war elephants and infantry. The empire maintained a sophisticated system of frontier defenses and could field massive armies. Their constant wars with Rome and Byzantium shaped the ancient world.
Controlling key segments of the Silk Road, the Sasanians were major players in international trade. Their silver drachms became a standard currency across the ancient world. The empire had a sophisticated tax system and maintained royal monopolies on silk and other luxury goods.
