China

China is considered one of the cradles of civilization: the first human inhabitants in the region arrived during the Paleolithic; by the late second millennium BCE, the earliest dynastic states had emerged in the Yellow River basin. The eighth to third centuries BCE saw a breakdown in the authority of the Zhou dynasty, accompanied by the emergence of administrative and military techniques, literature, philosophy, and historiography. In 221 BCE, China was unified under an emperor for the first time. Appointed non-hereditary officials began ruling counties instead of the aristocracy, ushering in more than two millennia of imperial dynasties including the Qin, Han, Tang, Yuan, Ming, and Qing. With the invention of gunpowder and paper, the establishment of the Silk Road, and the building of the Great Wall, Chinese culture—including languages, traditions, architecture, philosophy and technology—flourished and has heavily influenced both its neighbors and lands further afield. However, China began to cede parts of the country in the late 19th century to various European powers by a series of unequal treaties.
