What are the differences between the Russian state and the European states of the 17-18 centuries?

The tsar in Russia ruled the state as his own fiefdom, i.e. as property, relying not on the law, but on traditions and customs, while in the European states the arbitrariness of the monarch was limited by law. Serfdom was established in Russia, and feudal relations disappeared in Europe. In Russia, subsistence farming dominated economically, and manufacturing developed in Europe. In some European states there were already universities, science, medicine, art were developing, in Russia there was only church education.
