This is a family tree of the Sasanian emperors, their ancestors, and Sasanian princes/princesses.
The Sasanian dynasty was named after Sasan, the eponymous ancestor of the dynasty. It was founded by Ardashir I in 224, who defeated the last Parthian (Arsacid) king, Artabanus IV (Persian: اردوان Ardavan) and ended when the last Sasanian monarch, Yazdegerd III (632–651), lost a 19-year struggle to drive out the early Arab Caliphate, which was the first of the Islamic empires.
It is believed that the following dynasties and noble-families have ancestors among the Sassanian rulers:
The Sasanian Empire (/səˈsɑːnɪən/ or /səˈseɪnɪən/), 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 and named after the Sasanian dynasty from 224 to 651. 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.
The Sasanian Empire was founded by Ardashir I, after the fall of the Parthian Empire and the defeat of the last Arsacid king, Artabanus V. At its greatest extent, the Sasanian Empire encompassed all of today's Iran, Iraq, Eastern Arabia (Bahrain, Kuwait, Oman, Qatif, Qatar, UAE), the Levant (Syria, Lebanon, Israel, Jordan), the Caucasus (Armenia, Georgia, Azerbaijan, Dagestan, South Ossetia, Abkhazia), Egypt, large parts of Turkey, much of Central Asia (Afghanistan, Turkmenistan, Uzbekistan, Tajikistan), Yemen and Pakistan. According to a legend, the vexilloid of the Sasanian Empire was the Derafsh Kaviani.
