The Qin Dynasty was the first in history to unify much of modern-day China under a single emperor. However, the dynasty did not last very long - it began to collapse almost immediately after the founder's death.
Qin Dynasty Emperors of China
- Qin Shi Huangdi, ruled 221 - 210 BCE
- Qin Er Shi, r. 210 - 207 BCE
Qin Shi Huangdi was a great conquerer, and started work on northern border fortifications that later formed the basis of the Great Wall of China. His son was a much weaker ruler, however, so the dynasty collapsed in the third year of his reign.
