Federalism is a mode of government that combines a general level of government with a regional level of sub-unit governments, while dividing the powers of governing between the two levels of governments. Two illustrative examples of federated countries—one of the world's oldest federations, and one recently organized—are Australia and the Federated States of Micronesia, (Micronesia).
Local government is a generic term for the lowest tiers of governance or public administration within a particular sovereign state.
The autonomous communities are the first-level administrative divisions of Spain, created in accordance with the Spanish Constitution of 1978, with the aim of guaranteeing limited autonomy to the nationalities and regions that make up Spain.
Devolution is the statutory delegation of powers from the central government of a sovereign state to govern at a subnational level, such as a regional or local level. It is a form of administrative decentralization. Devolved territories have the power to make legislation relevant to the area, thus granting them a higher level of autonomy.
A federation is an entity characterized by a union of partially self-governing provinces, states, or other regions under a 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 without constitutional amendment.
A federated state is a territorial and constitutional community forming part of a federation. A federated state does not have international sovereignty since powers are divided between the other federated states and the federal government. Unlike international sovereign states, which have what is often referred to as Westphalian sovereignty, federated states operate under their domestic or federal law with relation to the rest of the world.
Chinese federalism refers to political theories that argue that China's central government should share sovereignty with regional entities under a form of federalism. Such proposals were made in the early twentieth century, in connection with the end of the Qing dynasty, as well as more recently, with a view to providing checks against the power of the central government and settling the relationship between Mainland China, Taiwan, Hong Kong, Macau, and other potential political entities.
A unitary state is a state or 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. 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 alter the statute, to override the decisions of devolved governments or expand their powers. The modern unitary state concept originated in France; in the aftermath of the Hundred Years' War, national feelings that emerged from the war unified France. The war accelerated the process of transforming France from a feudal monarchy to a unitary state. The French then later spread unitary states by conquests, throughout Europe during and after the Napoleonic Wars, and to the world through the vast French colonial empire.
Regionalism is a political ideology that seeks to increase the political power, influence and self-determination of the people of one or more subnational regions. It focuses on the "development of a political or social system based on one or more" regions, and/or the national, normative, or economic interests of a specific region, group of regions or another subnational entity, gaining strength from or aiming to strengthen the "consciousness of and loyalty to a distinct region with a homogeneous population", similarly to nationalism. More specifically, "regionalism refers to three distinct elements: movements demanding territorial autonomy within unitary states; the organization of the central state on a regional basis for the delivery of its policies including regional development policies; political decentralization and regional autonomy".
Political unitarism designates various theories, concepts or policies that advocate or enforce a fully unified and centralized system of government, with ultimate goal in creating a unitary state. In practice, unitarism is often manifested as a political doctrine or movement within complex political entities, advocating for the highest degree of political integration and unification, beyond mere administrative centralization.
A 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.
An autonomous administrative division is a subnational administrative division or internal territory of a sovereign state that has a degree of autonomy — self-governance — under the national government. Autonomous areas are distinct from other constituent units of a federation in that they possess unique powers for their given circumstances. Typically, it is either geographically distinct from the rest of the state or populated by a national minority, which may exercise home rule. Decentralization of self-governing powers and functions to such divisions is a way for a national government to try to increase democratic participation or administrative efficiency or to defuse internal conflicts. States that include autonomous areas may be federacies, federations, or confederations. Autonomous areas can be divided into territorial autonomies, subregional territorial autonomies, and local autonomies.
Asymmetric federalism or asymmetrical federalism is found in a federation or other types of union in which different constituent states possess different powers: one or more of the substates has considerably more autonomy than the other substates, although they have the same constitutional status. This is in contrast to symmetric federalism, where no distinction is made between constituent states. As a result, it is frequently proposed as a solution to the dissatisfaction that arises when one or more constituent units feel significantly different needs from the others, as the result of an ethnic, linguistic or cultural difference.
A 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 province is an administrative division within a country or state. The term derives from the ancient Roman provincia, which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy. The term province has since been adopted by many countries. In some countries with no actual provinces, "the provinces" is a metaphorical term meaning "outside the capital city".
Government in Spain is divided into three spheres or levels: the State itself, the regions or autonomous communities and local entities. These levels are not hierarchical, meaning there is no supremacy or primacy of one over the other, but rather they are separately defined by their jurisdictional powers.
Ethnic federalism, multi-ethnic or multi-national federalism, is a form of federal system in which the federated regional or state units are defined by ethnicity. Ethnic federal systems have been created in attempts to accommodate demands for ethnic autonomy and manage inter-ethnic tensions within a state. They have not always succeeded in this: problems inherent in the construction and maintenance of an ethnic federation have led to some states or sub-divisions of a state into either breaking up, resorting to authoritarian repression, or resorting to ethnocracy, ethnic segregation, population transfer, internal displacement, ethnic cleansing, and/or even ethnicity-based attacks and pogroms.
