Feudalism is defined as a Medieval European political, economic and social system from the 9th to 15th century.
The 'feudal system,' as most British and American medievalists use the term, describes a complex network or web or personal loyalties and (sometimes) tenure that defined how the nobility of the High Middle Ages were connected to one another and gave shape to how they ruled over each other and the peasantry.
