HISTORY OF CHINA

Xia Dynasty (c. 2070 – 1600 BCE)

Founded by the legendary Yu the Great (c. 2123 – 2025 BCE), the Xia Dynasty inaugurated dynastic rule in China. Yu is remembered for devising a system of irrigation canals that put an end to the floods that plagued the Chinese heartland, allowing communities to flourish along the Yellow River and its tributaries

Shang Dynasty (c. 1600 – 1050 BCE)

The earliest recorded Chinese dynasty supported by archaeological evidence, the Shang Dynasty saw more than 30 kings ruling much of the area along the Yellow River. Under this dynasty, there were advances in maths, astronomy, art and military technology. They also used a highly developed calendar system and an early form of the Chinese language
