The French Revolution was a direct response to absolute monarchism so yeah, you can’t stop people from protesting by making dissent illegal.

The current Saudi government is also an absolute monarchy as it happens. The definition of an “absolute” in political terminology is the ability to create laws by decree btw, it’s not necessarily that an executive power has made all dissent illegal or runs their government completely unopposed. These things usually lead from one to another but you’d never find a “true” absolute ruler if you followed the popular definition.
