An Absolute Monarchy that has an upper class revolt merely deposes and replaces the King. This is what you do to get rid of a completely worthless arse of a King. A lower class revolt creates a Republic.

As a Republic an upper class revolution creates a Constitutional Monarchy, while a lower class revolt similarly doesn't change the government type.

As a Constitutional Monarchy an upper class revolt produces an Absolute Monarchy and a lower class revolt creates a Republic. While having a monarch, a Constitutional Monarchy thus has absolutely no way to get rid of an inbred donkey of a King/Queen with one simple revolt.
