Seleucia ad Tigrim (Scope note)

Founded in c.305 BC by Seleucus I Nicator, founder of the Seleucid dynasty. Seleucia stood on the west bank of the Tigris River, opposite the small town of Opis (which later became Ctesiphon). The city was conquered by the Parthians in c.141BC and remained under Parthian rule until it was attacked and burned by the Roman emperor Trajan in AD 117. Trajan’s successor Hadrian ceded the city back to the Parthians the following year, but the city was finally destroyed in AD164 by the Roman general Avidius Cassius. The area became part of the Sasanian Empire and a new city, Veh Ardashir, was built on the site by the founder of the Sasanian dynasty, Ardashir I. The modern site is Tell Umar.
