In the last episode of the documentary Islam : Empire of Faith covers the history of the expansionist Ottoman Empire and its ambitious sultans through the reign of Suleyman the Magnificent. As Academy Award-winning actor Ben Kingsley explains, a key successful aspect of the Ottoman method of expansion was to leave in place the clerks -- the bureaucracy -- of the conquered territories. The Sunni Ottoman regime had more trouble from their rival Safavid Dynasty of Shiite Muslims than from their vanquished Christian subjects. Highlights of this program include footage from old Constantinople and from Istanbul, marvelous Islamic architecture, and mosaics and paintings portraying historical events.
