Life In Iran

In 632 raiders from the Arab peninsula began attacking the Sassanid Empire. Iran was defeated in the Battle of al-Qādisiyyah, paving way for the Muslim conquest of Persia.
During the Parthian and later Sassanid eras, trade on the Silk Road was a significant factor in the development of the great civilizations of China, Egypt, Mesopotamia, Persia, Indian subcontinent, and Rome, and helped to lay the foundations for the modern world. Parthian remains display classical Greek influences in some instances and retain their oriental mode in others, a clear expression of the cultural diversity that characterized Parthian art and life.
The Parthians were innovators of many architecture designs such as that of Ctesiphon, which later influenced European Romanesque architecture. Under the Sassanids, Iran expanded relations with China. Arts, music, and architecture greatly flourished, and centers such as the School of Nisibis and Academy of Gundishapur became world renowned centers of science and scholarship.
