One of the goals of Omniatlas is to try to provide an objective and timeless display of political power. To that end we have a check system to determine whether or not a given country is under another's influence or control.
In Omniatlas, a political entity is considered to be fully independent if it is self-governing, manages its own foreign relations, has complete rule over a territory, and is not under the authority of an outside power. If it fails in one of these points, it is considered to be under the influence of another power. If it fails in two or more, it is considered to be under another power's control.
These four signs are based on the classical definition of a sovereign state, except that a sovereign state must have a permanent population and defined borders. By eliminating these last two conditions, we allow for a definition of sovereignty which covers not just states but factions, tribes, insurgents, and other independent political organizations.
Who is the government?
If representatives of an outside power occupy the highest levels of political power, a polity is considered to lack self-government.
Who signs treaties? Who determines war and peace?
If an outside power conducts or supervises its foreign relations, a polity is considered to lack control over its foreign relations.
Who are the police?
If an outside power handles law enforcement, a polity is considered to lack territorial control.
