What new appeared in the structure of society in the Frankish state in the eighth century?

In the 8th century, feudal orders began to form here. That is, an early feudal monarchy arose. A vassalage system appeared, which assumed the subordination of some to others. Now the vassals received land allotments for their faithful service. On the other hand, slavery was abolished. Now the peasants worked on the lands of their feudal lords. Thus, the Frankish kingdom was able to become one of the very first feudal states.
