An example of a limited government is Constitutional Monarchy. Limited government, like here, is when the ruler can't control everything. the only problem with Constitutional Monarchy is that the king or queen cannot be elected.
I don't like the queen!
TYPES OF GOVERNMENTS By Violet Long
Unlimited governments are when the government has complete power and not many to regulate them. An example is Fidel Castro in Cuba. He was a Dictator (Dictatorship.) Because he could do whatever he wanted he did some good and bad things.
For example, he offered free education and healthcare for everyone, but on the other hand, he eliminated all free press and the implementation of a one-party state.
The government doesn't have to be limited or unlimited if it doesn't exist. this is called Anarchy. Anarchy is a bad idea and a mess because it has no law enforcement, either.
In my opinion, different government types can all be good at certain times. (Except for anarchy.)
