The term 'during the knight-time' refers to the period of time in which feudalism was practiced. Feudalism was a system of government and social structure that existed in Europe from the 9th to the 15th centuries. It was based on the granting of land by a lord to a vassal in exchange for loyalty, military service, and other obligations. The term 'FEUDAL' is derived from the Latin word feodum, meaning 'FIEF'.
