Final answer:
Feudalism is the system where kings divide land among lords and nobles who provide military service and land produce in return.
Step-by-step explanation:
The system of government where the king divides the land among his lords and nobles, who in turn provide the king with military service and produce from the land, is known as feudalism. Under this system, nobles, known as lords, would place vassals in charge of pieces of land known as fiefs. These vassals, in return for the land and the resources it provided, pledged military service and other forms of assistance to their lords. This hierarchical system emerged in Europe in the ninth century, notably within the ashes of the Carolingian world. Feudal relationships were based on mutual obligations and protections, as each vassal had the right to extract wealth from his land to finance their military service to the lord, and by extension, to the king.
