Geography, territory as a political construct, is also relevant from the perspective of international law as well. According to Montevideo Convention which sets out the parameters of a state spells out four aspects for a political entity to be properly called a state: defined territory, permanent people, centralized authority and sovereignty. All these aspects and characteristics are basic criteria to define the modern nation state and to distinguish it from other political entities. Both “defined” and “territory” in the term defined territory deserve close attention as they bear significance for a proper definition. Territory refers to a physical space, mostly to land. But it should be noted that territory is not an ordinary type of land and that it is a qualified and political component. As a physical space, territory is an integral element of the state which cannot possibly be separated from it.
Because it is different from an ordinary type of land, territory appears to be a significant criterion to define the state. For this reason, to make distinction between the modern nation state and the states before the arrival of nation state, the first is also referred to as territorial state. The difference is that in the definition of modern nation state, physical space is attributed to the state as an integral and indispensable element. In other words, only a state has territory which holds a political connotation and implies a monopolistic political control. In other words, a state, by definition and out of legal necessity, has to have a territory; and it is not possible to speak of a state without a defined territory.
Additionally, only one state has monopoly and control over a territory; therefore, there is connection between territory and the exclusive jurisdiction of a state. This jurisdiction and monopolistic authority by a state over a certain territory is assured under international law which, by the cardinal principle of non-intervention, protects the territorial integrity of all sovereign states. This means that territory, associated with the state and considered an inseparable part of it, is legally protected and that violations directed against its integrity lead to legal responsibility. Thus, it is fair to argue that territory holds a political, as well as legal meaning. “Defined” complements the nature of protection and certainty ascribed to the territory under international law. “Defined territory” implies that the borders of a state are properly identified and ascertained and that their inviolability is stressed and protected by the community of states. The borders of nation states are specified with utmost certainty, often by imagined lines that exist as constructions. Ideally, natural sites are taken as points of references; but legally speaking, they are not the borders. So, it is reasonable to take a mountain that separates two states as point of reference in identifying the borders.
As also understood from the information given, the answer is E. All of the statements above related to the concept of defined territory are correct.
