Multinational stateA multinational state or a multinational union is a sovereign entity that comprises two or more nations or states. This contrasts with a nation state, where a single nation accounts for the bulk of the population. Depending on the definition of "nation" (which touches on ethnicity, language, and political identity), a multinational state is usually multicultural or multilingual, and is geographically composed of more than one country, such as the countries of the United Kingdom.
Unitary stateA unitary state is a sovereign state governed as a single entity in which the central government is the supreme authority. The central government may create or abolish administrative divisions (sub-national units). Such units exercise only the powers that the central government chooses to delegate. Although political power may be delegated through devolution to regional or local governments by statute, the central government may abrogate the acts of devolved governments, curtail or expand their powers.
Federal monarchyA federal monarchy, in the strict sense, is a federation of states with a single monarch as overall head of the federation, but retaining different monarchs, or having a non-monarchical system of government, in the various states joined to the federation. The term was introduced into English political and historical discourse by Edward Augustus Freeman, in his History of Federal Government (1863). Freeman himself thought a federal monarchy only possible in the abstract.
PolityA polity is a term for an identifiable political entity, defined as a group of people with a collective identity, who are organized by some form of institutionalized social relations, and have a capacity to mobilize resources. A polity can be any other group of people organized for governance (such as a corporate board), the government of a country, or of a country subdivision. A polity may be a republic administered by an elected representative, or the realm of a hereditary monarch.
Central governmentA central government is the government that is a controlling power over a unitary state. Another distinct but sovereign political entity is a federal government, which may have distinct powers at various levels of government, authorized or delegated to it by the federation and mutually agreed upon by each of the federated states. Though inappropriate, the adjective "central" is also sometimes used to describe the government of a federation, such as in India. The structure of central governments varies.
ExtraditionIn an extradition, one jurisdiction delivers a person accused or convicted of committing a crime in another jurisdiction, over to the other's law enforcement. It is a cooperative law enforcement procedure between the two jurisdictions and depends on the arrangements made between them. In addition to legal aspects of the process, extradition also involves the physical transfer of custody of the person being extradited to the legal authority of the requesting jurisdiction.
Political unionA political union is a type of political entity which is composed of, or created from, smaller polities, or the process which achieves this. These smaller polities are usually called federated states and federal territories in a federal government; and prefectures, regions, or provinces in the case of a centralised government. This form of government may be created through voluntary and mutual cession and is described as unionism by its constituent members and proponents.
RatificationRatification is a principal's legal confirmation of an act of its agent. In international law, ratification is the process by which a state declares its consent to be bound to a treaty. In the case of bilateral treaties, ratification is usually accomplished by exchanging the requisite instruments, and in the case of multilateral treaties, the usual procedure is for the depositary to collect the ratifications of all states, keeping all parties informed of the situation.
Centralized governmentA centralized government (also united government) is one in which both executive and legislative power is concentrated centrally at the higher level as opposed to it being more distributed at various lower level governments. In a national context, centralization occurs in the transfer of power to a typically unitary sovereign nation state. Executive and/or legislative power is then minimally delegated to unit subdivisions (state, county, municipal and other local authorities).
FederacyA federacy is a form of government where one or several substate units enjoy considerably more independence than the majority of the substate units. To some extent, such an arrangement can be considered to be similar to asymmetric federalism. A federacy is a form of government with features of both a federation and unitary state. In a federacy, at least one of the constituent parts of the state is autonomous, while the other constituent parts are either not autonomous or comparatively less autonomous.
