History of ChinaThe history of China spans several millennia across a wide geographical area. The notion of "China" can be understood under many diverse historiographical, cultural, geographic, and political lenses, and has evolved tremendously over time. Each region now understood to be part of the Chinese world has alternated between many periods of unity, fracture, prosperity, and hardship. Classical Chinese civilization first emerged in the Yellow River valley, which along with the Yangtze and Pearl valleys now constitute the geographic core of China and have for the majority of its imperial history.
