Economics of feudal Japan
In Feudal Japan between 1185 CE and 1868 CE , vassals offered their loyalty and services (military or other) to a landlord in exchange for access to a portion of land and its harvest. In such a system, political power is diverted from a central monarch and control is divided up amongst wealthy landowners and warlords.
