how long ago was the qin dynasty
The short-lived Qin Dynasty was the first to unite China as a country under an emperor instead of a ruling clan. A bureaucratic government was introduced, and was continued by the less-extreme Han Dynasty. The Qin Dynasty (221â206 BC) was the first and shortest imperial dynasty in China, famous for great building projects like the Great Wall and the Terracotta Army. Liu Bang, a peasant leader, overthrew the unpopular Qin regime and established the Han Dynasty.
