IPA: /ˈfjuːdəlɪzəm/
KK: /ˈfjuːdəlɪzəm/
A system of government and economy that existed in Europe from the 9th to the 15th century, where land was owned by lords and worked by vassals who provided services in return.
During the Middle Ages, feudalism was the dominant social system in Europe.
Feudalism is derived from "feudalis" (from Old French *feodal*, meaning pertaining to a fief or estate) and the suffix "-ism" (meaning a system or practice). The term refers to the social and economic system based on land ownership and the relationships between lords and vassals in medieval Europe.
Think of 'feudal' relating to land and estates, and '-ism' indicating a system. This helps you remember that feudalism is a system based on land ownership and the relationships formed around it.
