Autonomy is enacted in a region other than the capital of a country in the national parliament. Once the law has been approved, elections to the autonomous Parliament are initiated among the parties of the region.
The national parliament can appoint a governor, who will receive gold pay for his office and remain in power until by law is assigned to another or cancel the autonomy. If the country's form of government is a republic, the governor will be able to replenish resources and build buildings instantaneously.
Autonomies have some self-management and their own coffers.
The taxes and laws applied in the autonomy have their effect differentially in the territory with respect to the national standard, although the national decrees modify and update their state, imposing itself.
The Profit division establishes the percentage of the taxes that will stop in the coffers of autonomy. The rest goes to the national budget. This is manually modified by the Minister of Economy, the monarch or the dictator.
If you are granted independence, the coffers are now held as a state budget.
