The Arab East of the 12th century, enslaved by the Turks, besieged by the Crusaders, filled with a motley rabble from all corners of the earth, remained the center of science and culture of the Middle Ages. A talented young man from a noble family, Hasan al-Sabbah, was accepted into the Ismaili brotherhood and sent to study in the great city al-Qahira, the capital of the righteous imams, to become a preacher. Wars and wanderings, palace intrigues and the treachery of robbers, even friendship with a wine lover and writer of destructive poems Omar Khayyam did not prevent al-Sabbah from creating a state based on the word of Truth, whose light has scattered throughout the world and shines to this day.
