What Is Qin Dynasty?
Qin Dynasty (221 BC — 207 BC) was the first centralized empire in the ancient history of China, which had a unified language, currency, and measurement, after having defeated the other six kingdoms of the Warring States Period (403 BC — 221 BC).
Founding emperor Qin Shi Huang who constructed Great Wall and Terracotta Army, was the first Emperor of China.
Qin's political system set a foundation for Chinese feudal empires in the next 2000 years and was the starting point of "Great Unity" in Chinese culture.
In 14 years of the Qin Empire, three emperors ruled the empire.
