What changes have occurred in state power (Russia) with the advent of absolutism in the 17th century?

The tendency towards absolute monarchy was shown by Peter the Great. He sought to concentrate all the reins of government in his own hands. To do this, he separated the church from the state apparatus, introduced new secular laws, and streamlined relations between people. This made it possible to get rid of a lot of advisors, including those incompetent ones. Enlightened absolutism manifested itself during the reign of Catherine 2. She introduced elements of Western traditions, popularized culture in our country. But there was still no parliament.
