The first provinces were created by the Mongol-led
Yuan dynasty, and have remained one of the most stable forms of Chinese government since then. They were created to help the Imperial court manage local county governments, which were too numerous and far-flung to be managed directly. The number of provinces grew steadily during subsequent dynasties, reaching 28 by the time of the
Republic of China. During the
Warlord Era, provinces became largely or completely autonomous and exercised significant national influence. Province-level units proliferated and under the early People's Republic there were over 50. Political boundaries are, in part, established to counterbalance the influence of economic factors. For instance, the
Yangtze Delta is divided among the provinces of
Zhejiang,
Jiangsu, and
Anhui. This division ensures that economic strength is distributed, preventing any single region from potentially overpowering the state. == List of provinces ==
