In what way the feudal system like the Roman empire?

In both the feudal system and the Roman Empire, workers were obliged to pay taxes to their masters, nobles, and owners of their lands.

Explanation:

The origin of feudalism can be traced to the crisis of the Western Roman Empire and the barbarian invasions. Feudalism was a political, economic and social system organized from land ownership.

In the feudal system, the king granted land to great lords. These, in turn, gave land to other less powerful masters, called knights, who in turn fought in their favor. He who bestowed the land was a warlord, and who received it was a vassal. Relations between the suzerain and the vassal were mutually binding, established through an oath of allegiance. When a vassal was invested in the possession of the fiefdom by the overlord, he vowed to give him military aid. The overlord, in turn, was obliged to give the vassal legal and military protection.

Feudalism in the Holy Roman Empire was a politico-economic system of relationships between liege lords and enfeoffed vassals (or feudatories) that formed the basis of the social structure within the Holy Roman Empire during the High Middle Ages ... It obliged the feudatory to render personal services to the lord.
