What are the main signs of land relations in a feudal society?

The main feature of land relations in the Middle Ages was that the peasants worked on the lands of their feudal lords, for which they were forced to pay a tax in kind or in cash. Such a system was common in all European states during this time period. For a very long period it existed in the Russian state. Despite the fact that in Europe feudalism began to fade into the background in the 17th and 18th centuries. In the same period of time in Russia, on the contrary, it strengthened even more. This became the reason for the global enslavement of the peasants.
