Western Zhou, 850–771 BCE
Autocracy · Monarchy · East Asia · Archaic World era
A declining feudal monarchy legitimized by the Mandate of Heaven, its royal authority draining to increasingly independent lords.
The Western Zhou king reigned as Son of Heaven over a network of vassal lords bound by kinship, investiture and ritual obligation rather than direct administration. As royal domains and prestige contracted, the lords grew more independent and border peoples pressed the frontier. The dynasty’s western capital was sacked in 771, and the court’s flight east opened the more contested Spring and Autumn order.
