Brief
Khosrow II — "Khosrow the Victorious" — was the last great shah of Sasanian Persia (590–628). His empire swallowed half of Byzantium's lands, then shattered; the tradition remembers him as the king who tore up the Prophet's letter.
Life
Khosrow came to power as a fugitive who had appealed to Byzantium, then spent two decades waging the war that made Sasanian armies masters of Egypt and stood before Constantinople 1. Heraclius's counter-invasion broke the empire; in February 628 Khosrow was deposed by his own son and executed 2.
The Islamic sources place his fall in pointed sequence with a letter: the Prophet is reported to have written "From Muhammad, God's Messenger, to Kisra, king of Persia," and the shah to have torn the letter and ordered the governor of Yemen to seize the Prophet — before news of his own overthrow arrived {cite:ibn-sad-tabaqat-bewley, tabari-bosworth-1999}.
Legacy
Within a generation of his death the whole Sasanian world — the empire that had ruled Iran for four centuries — was absorbed into the caliphate. In Islamic memory he is the proud king warned and ignored; in Iranian memory, the beginning of an ending.
For young visitors
The king of the world's second superpower tore up the Prophet's letter. Within months he was dead — and within thirty years his whole empire was gone.
