The land received by a nobleman from a king was called a "fief." This arrangement was part of the feudal system, where the nobleman, or vassal, would manage the land and provide military service in return for protection and the right to the resources from the land. The king granted these lands to secure loyalty and support from the nobility.

The answer depends somewhat on how specific or particular you want to be. A fief is the land granted to a vassal under feudalism. A manor is an isolated, self-contained village of sorts that is the entire (or less) land of a fief. A manor is typically 1000 acres and approximately 200 people. It is built around a manor house. Technically, there could be many manors on a single fief. So while a fief is the land granted by a lord to a vassal, the manor is the specific economic system of the manor-centric living system of the peasants and nobles in the middle ages.
fief or feoff
(A fief, or land held in trust, was given to a lower vassal or serf in the feudal system. The word fee developed from the share, tribute, or rent paid to the lord, hence landlord)"The son inherited his father's fief, and had many serfs who farmed the land.""Under feudalism, a noble could not sell his fief to another."
Fief-holding was a system in which vassals were granted land (fiefs) by lords in exchange for loyalty and military service. Manorialism, on the other hand, was an economic system centered around the manor, a large estate controlled by a lord. Fiefs were often part of manors, with vassals holding land from the lord within the manor and providing labor and resources in return.

A fief.
Under the system of feudalism, a fief belonged to the category of land held by a vassal in exchange for military service and loyalty to a lord. The fief typically included not just land but also the rights to the resources and the labor of the peasants living on it. This arrangement created a hierarchical structure where lords granted fiefs to vassals, who in turn owed allegiance and protection to their lords.
