What testifies to the emergence of feudal relations?

The first sign is complete dominion over the land. The feudal lord was the only ruler of the land and gave people the right to work on it. The second sign is that the feudal lord could set the wages himself from his land, regardless of whether the workers had money or not. The third sign is the dependence of the farmer on the feudal lord, a vivid example of feudal Japan, where there is little good land and the peasants agreed to work on the worst conditions. Under the conditions of feudal power, the ruler was, in fact, considered the king, but in a certain area.
