I. Traditional Subjects of International Law
A. States
In addition to controlling territory, States have lawmaking and executive functions. States have full legal capacity, that is, they have the ability to be vested with rights and to incur obligations.
B. Insurgents
Insurgents are a destabilizing factor, which makes States reluctant to accept them, unless they show some of the attributes of sovereignty (e.g. control of a defined territory). Their existence is temporary; they either prevail and become a full-fledged state, or fail and disappear.

Other factors might be relevant such as self-determination and recognition, but one thing is clear – the relevant framework revolves essentially around territorial effectiveness.
The need for defined territory focuses upon requirement for
