Osmanoglu is 16th in line to become the Head of the Imperial House of Osman. The Ottoman Empire was succeeded by the Republic of Turkey in 1923 after the monarchy was abolished the previous year; the members of the royal Ottoman (Turkish: Osmanlı) family were initially exiled to Europe. Osmanoglu uses his everyday nickname "Naz" and his last name (without the modern Turkish diacritic ğ) as his personal, professional, and stage name, being known simply as Naz Osmanoglu.
