Yazdegerd III
Last King of Kings of the Sasanian Empire
"The empire of a thousand years cannot end in my lifetime."
Biography
The last emperor of Sasanian Persia, Yazdegerd III came to the throne as a boy of eight, in the chaos that followed the ruinous war with Byzantium and the murder of his grandfather Khosrow II. He inherited a shattered, divided empire just as the Arab storm broke, and he spent his short reign in flight and futile resistance. His armies were destroyed at Qadisiyyah and then, decisively, at Nahavand in 642 — the 'Victory of Victories' that ended organised Persian resistance. Yazdegerd fled ever eastward across his crumbling empire, seeking help from local lords and even from Tang China, but found none. In 651 he was murdered near Merv, by tradition by a miller who coveted his jewels. With him ended the Sasanian dynasty and over a thousand years of Persian imperial independence, and Iran began its long transformation into a land of Islam.

His son Peroz fled all the way to the court of Tang China, where he was given a title and a Persian community in exile persisted for generations — the last flicker of the Sasanian royal line.
