What do you see as the reasons for the change in the nobility in the 17th century?

In the 17th century, there were changes in the social structure of the population. Boyars and nobles ceased to differ from each other and became sovereign people. This meant that they began to serve the state, and their social position depended on the position they held, and wealth and nobility faded into the background. This served as the abolition of parochialism and the noble estates turned into hereditary estates. Further, the position of the nobles was strengthened, thanks to the introduction of serfdom in 1649 and the formation of a “local order” years later.
