Khan Academy: An Introduction to the Tang Dynasty (618 906)

Scholars often refer to the Tang (618-906) and Song (960-1279) dynasties as the "medieval" period of China. The civilizations of the Tang (618-906) and Song (960-1279) dynasties of China were among the most advanced civilizations in the world at the time. Discoveries in the realms of science, art, philosophy, and technology - combined with a curiosity about the world around them - provided the men and women of this period with a worldview and level of sophistication that in many ways were unrivaled until much later times, even in China itself.
