Which two governments would share the characteristic of being ruled by a single leader?

An absolute monarchy and an autocracy.

In absolute monarchy, the king is the ultimate ruler. King holds the supreme authority just like in ancient times. The roman empire, the greek empire are a few examples of absolute monarchy. Whereas in Autocracy means rule by the self, meaning the system of government by one person with absolute power.

So, these are the two governments would share the characteristic of being ruled by a single leader.
