In the first half of the period from 1400 to 1600 A.D., Iran is ruled by a series of different Turko-Mongol dynasties such as the Jalayirids, Timurids, Qara Quyunlu, and Aq Quyunlu. By the early sixteenth century, the whole area is unified under the rule of the Safavids, possibly the most successful dynasty to emerge from Iran in the Islamic era. The period is recognized for artistic production, particularly the arts of the book. Textiles, carpets, and ceramics also become important in the international market.
