What beliefs are common to both 17th century absolutism and 20th century totalitarianism?

There are a few common beliefs:

• There should be a single leader with nearly complete power. Any dissenters to the power are dangerous and should be strongly punished.
• The ruling leader creates a quasi-divine persona of unimpeachability and perfection. The leader and the state are effectively interchangeable.
• A regimented bureaucracy is key to enforcing the will of the leader
• Militaries are necessary to protect the state from threats both within and without.
