In 1967, he married Maryam Eghbal, the Christian daughter of Manouchehr Eghbal, who was earlier married to one of his uncles, a half-brother of the Shah. Together they had two sons:
H.H. Prince Nader Shafiq (born 15 March 1968)
H.H. Prince Dara Shafiq (born 1970).
Shahryar Shafiq was an Imperial Iranian NavyCaptain, and along with his cousin Prince Kamyar Pahlavi, the only members of the Pahlavi Dynasty who chose military careers. After the disaster of the Islamic Revolution that struck Iran in February 1979, he was the only member of Dynasty to stay inside Iran and keep fighting against the Islamic revolutionaries, up to the point when he had to flee in a small boat from the Persian Gulf to Kuwait, under heavy fire.
After exile, he joined his family in Paris, France and began organizing a resistance movement inside Iran. He was assassinated in Paris on December 7, 1979, being shot twice in the head by the agents of the Islamic Republic on the Rue Pergolese.
