The Postclassical Era

I expect that the Postclassical Era is mainly going to be about the restoration of political and social order.  The newly found Islamic faith will overcome the Sasanid empire. The Sui and Tang dynasties will restore centralized government in China. Regional kingdoms will  take authority in India, and western Europe will rule with a decentralized government.  Long distance trade and cross cultural communication will also be restored.  Increased agricultural production will lead to an increase in human population.  The increasing human population will devote their efforts in trade and manufacturing, such as the prominent production sites in China, India, and the eastern Mediterranean.  Increase in trade and manufacturing will inspire development of new technology, such as gunpowder, the magnetic compass, and printing technologies.  New faiths will arise, such as the Islamic faith, and already existing faiths will expand.  Buddhism expands beyond India and central Asia into China and other east and southeast Asian lands.  Christianity also prospers in the Mediterranean basin, especially the Byzantine empire, and spreads to eastern, western, and northern Europe as well as Russia.
