Pious Muslims regard all history prior to the Prophet Muhammad as largely irrelevant, and they consider all history after the revelation of the Quran to revolve around the Muslim ummah. The main exceptions are Turkish, Iranian, and Egyptian nationalists, who argue that even prior to Muhammad their particular nation was the fountainhead of all that was good about humanity, and that even after the revelation of the Quran, it was mainly their people who preserved the purity of Islam and spread its glory.
