Chinese nobility refers to the elite social class in ancient China, often associated with the ruling families and high-ranking officials. This class held significant power and influence, particularly during dynasties like the Tang and Song. Nobles typically owned large estates and had access to education, allowing them to participate in government and military affairs. The structure of Chinese nobility was hierarchical, with titles such as duke, marquis, and count denoting rank. Nobles were expected to uphold Confucian values, which emphasized loyalty, filial piety, and moral integrity. Over time, the rise of the scholar-official system diminished the power of hereditary nobility, leading to a more meritocratic society.
