Ch’in and Han Dynasty
After the beginning of the Shang Dynasty, it took over 1500 years for the vast land of China to get unified. This unification of China happened under two legendary dynasties, the Ch’in and the Han. Though the Ch’in dynasty could not sustain after the end of its founder, the Han dynasty remained strong and upfront for over four centuries. Though the major transformation of China can be credited to these two dynasties, the ground work had been down by the earlier rulers.
