SovereigntySovereignty can generally be defined as supreme authority. Sovereignty entails hierarchy within the state, as well as external autonomy for states. In any state, sovereignty is assigned to the person, body or institution that has the ultimate authority over other people in order to establish a law or change existing laws. In political theory, sovereignty is a substantive term designating supreme legitimate authority over some polity. In international law, sovereignty is the exercise of power by a state.
Supranational unionA supranational union is a type of international organization that is empowered to directly exercise some of the powers and functions otherwise reserved to states. A supranational organization involves a greater transfer of or limitation of state sovereignty than other kinds of international organizations. The European Union (EU) has been described as a paradigmatic case of a supranational organization, as it has deep political, economic and social integration, which includes a common market, joint border control, a supreme court, and regular popular elections.
Local governmentLocal government is a generic term for the lowest tiers of public administration within a particular sovereign state. This particular usage of the word government refers specifically to a level of administration that is both geographically localised and has limited powers. While in some countries, "government" is normally reserved purely for a national administration (government) (which may be known as a central government or federal government), the term local government is always used specifically in contrast to national government – as well as, in many cases, the activities of sub-national, first-level administrative divisions (which are generally known by names such as cantons, provinces, states, oblasts, or regions).
State (polity)A state is a centralized political organization that imposes and enforces rules over a population within a territory. Definitions of a state are disputed. One widely used definition comes from the sociologist Max Weber: a "state" is a polity that maintains a monopoly on the legitimate use of violence, although other definitions are common. Absence of a state does not preclude the existence of a society, such as stateless societies like the Haudenosaunee Confederacy that "do not have either purely or even primarily political institutions or roles".
FederationA federation (also known as a federal state) is a political entity characterized by a union of partially self-governing provinces, states, or other regions under a central federal government (federalism). In a federation, the self-governing status of the component states, as well as the division of power between them and the central government, is constitutionally entrenched and may not be altered by a unilateral decision, neither by the component states nor the federal political body.
NationA nation is a large type of social organization where a collective identity has emerged from a combination of shared features across a given population, such as language, history, ethnicity, culture, territory and/or society. What constitutes a nation can vary widely, as some nations are constructed around ethnicity (see ethnic nationalism) while others are bound by political constitutions (see civic nationalism and multiculturalism). A nation is generally more overtly political than an ethnic group.
