État souverain | EPFL Graph Search

A sovereign state is a state that has the highest authority over a territory. International law defines sovereign states as having a permanent population, defined territory, a government not under another, and the capacity to interact with other sovereign states. It is also commonly understood that a sovereign state is independent. According to the declarative theory of statehood, a sovereign state can exist without being recognised by other sovereign states. Unrecognised states will often find it difficult to exercise full treaty-making powers or engage in diplomatic relations with other sovereign states. Since the end of the 19th century, almost the entire globe has been divided into sections (countries) with more or less defined borders assigned to different states. Previously, quite large plots of land were either unclaimed or deserted, or inhabited by nomadic peoples that were not organized into states. However, even in modern states, there are large remote areas, such as the Amazon's tropical forests, that are either uninhabited or inhabited exclusively or mainly by indigenous people (and some of them are still not in constant contact). There are also states that do not exercise de facto control over their entire territory, or where this control is disputed. Currently, the international community includes more than 200 sovereign states, most of which are represented in the United Nations. These states exist in a system of international relations, where each state takes into account the policies of other states by making its own calculations. From this point of view, States are integrated into the international system of special internal and external security and legitimization of the dilemma. Recently, the concept of the international community has been formed to refer to a group of States that have established rules, procedures and institutions for the implementation of relations. Thus, the foundation for international law, diplomacy between officially recognized sovereign states, their organizations and formal regimes has been laid.
