China’s golden age of expansion occurred during which Dynasty?
The Tang Dynasty (600-1600 C.E)
The rise of the Tang dynasty in China mirrored the rise of the Han over 800 years earlier. Like the Han dynasty before them, the Tang dynasty was created after the fall of a ruthless leadership. And like the Han before them, the Tang dynasty had their own powerful leader, Emperor Tai-tsung.
Actually, the Tang Dynasty lasted from 618 to 907 CE. After that there was a period of fragmentation before the Song Dynasty came and ruled from 960 to 1279. Then the Mongols came in and started the Yuan Dynasty, from 1279 to 1368. Then there were the Ming from 1368 to 1644, and finally the Qing from 1644 to 1912.
Now, as for which dynasty expanded the most, there are really two answers. In terms of a large continuous empire, China had typically been centered around its core area throughout most of it’s early dynasties until the Yuan and Qing dynasties, both of whom were from northern Mongolian areas. These dynasties incorporated western China and northern China into China proper.
The second answer relates to when China was most expansionist in terms of wanting to explore and expand its influence. This would be during the Ming dynasty. It reached a high point under the admiral Zheng He with his enormous expedition all over Asia. But for many complicated reasons, not long after this China became more isolationist.
