The Mongolian conquest of Persia ended a golden age, which was a peak period of Islamic literature, philosophy, medicine, and art.
The Mongol conquest of Khwarezmia from 1219 to 1221 meant the beginning of the Mongol conquest of the Islamic states. The Mongol expansion ended in the conquest of virtually all of Asia (as well as parts of Eastern Europe) with the exception of Japan, the Mamluk Sultanate of Egypt, Siberia, and most of the Indian subcontinent and Southeast Asia.
