FedCom is a Federation divided into semi-autonomous regions called Member-States, Provinces, and Territories. These titles are only used as needed, so they can be empty under certain circumstances.
Territories: Generally, when a region is initially annexed by FedCom, it becomes a Territory. These unincorporated regions are generally managed by a government established by FedCom's Federal Government, and run as a puppet state. During this period, the Federal Government oversees the territory's development, launching programs to improve it.
Provinces: As a territory develops, it will eventually transition to Province status, and will become self-governing. The Federal Government ceases to have direct control over the region, and the population of that region takes over managing their own affairs.
Member-States: Once the Province stabilizes and develops a fully functional economy and government, it will become a Member-State, and achieve a high degree of political autonomy.
