If you wish to change your Government then you must have a Revolution to overthrow the current government.

The Revolution will cost you goldGold small and your towns will go into Anarchy until the new Government can gain control.

Gold costs

It will cost you 5,000 Gold small times the total number of cities that you own.

Amount of Anarchy gained

It will cause ALL of your towns, including your capital, to go into Anarchy that will last for (30 times the total number of cities that you own) in minutes.

This can be prevented if you have your Palaces/Governor's Residences one (1) level higher than what is normally required for that town's level, before you change your form of government.
