Persia - The Sasanian Empire

The Sasanian Empire (also known as Sassanian, Sasanid, Sassanid or Neo-Persian Empire), known to its inhabitants as Ērānshahr in Middle Persian language, was the last Iranian empire before the rise of Islam, ruled by the Sasanian dynasty from 224 AD to 651 AD. The Sasanian Empire, which succeeded the Parthian Empire, was recognized as one of the leading world powers alongside its neighboring arch rival the Roman-Byzantine Empire, for a period of more than 400 years.
