Sassanian
dynasty
Persian dynasty (AD 224–651).
Founded by Ardashir I (r.
AD 224–241) and named for his
ancestor Sasan (c. 1st century
AD), it replaced the Parthian
empire (see
Parthia). Its capital was
Ctesiphon. The dynasty battled the
Roman Republic and Empire and its successor the
Byzantine Empire in the west and the Kushans and Hephthalites in the east
throughout much of its existence. In the 3rd century its empire stretched from
Sogdiana and Georgia to northern Arabia, and from the Indus River to the
Tigris and Euphrates rivers. Traditions of the
Achaemenian dynasty were revived, Zoroastrianism was reestablished as the
state religion, and art and architecture experienced a renaissance. Its
important rulers included Shapur I (d. 272), Shapur II (309–379),
Khosrow I, and
Khosrow II. The Sasanids were the last native Persian dynasty before the
Arab conquest of the region in the late 7th century.
