"De jure", or legal, sovereignty concerns the expressed and institutionally recognised right to exercise control over a territory. "De facto", or actual, sovereignty is concerned with whether control in fact exists. Cooperation and respect of the populace; control of resources in, or moved into, an area; means of enforcement and security; and ability to carry out various functions of state all represent measures of "de facto" sovereignty. When control is practiced predominantly by military or police force it is considered "coercive sovereignty".
