  Unitary states

A 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 override the decisions of devolved governments, curtail their powers, 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. [1]


Unitary states stand in contrast to federations, also known as federal states. A large majority of the UN member countries, 166 out of 193, have a unitary system of government. [2]

Devolution compared with federalism

A unitary system of government can be considered to be the opposite of federalism. In federations, the provincial/regional governments share powers with the central government as equal actors through a written constitution, to which the consent of both is required to make amendments. This means that the sub-national units have a right to existence and powers that cannot be unilaterally changed by the central government. [3]

Unitary republics

Unitary monarchies

The United Kingdom of Great Britain and Northern Ireland is an example of a unitary state. Scotland, Wales and Northern Ireland have a degree of autonomous devolved power, but such power is delegated by the Parliament of the United Kingdom, which may enact laws unilaterally altering or abolishing devolution. Similarly in Spain, the devolved powers are delegated through the central government.

<span class="mw-page-title-main">Federalism</span> Political concept

Federalism is a mode of government that combines a general government with regional governments in a single political system, dividing the powers between the two. Johannes Althusius is considered the father of modern federalism along with Montesquieu. He notably exposed the bases of this political philosophy in Politica Methodice Digesta, Atque Exemplis Sacris et Profanis Illustrata (1603). Montesquieu sees in the Spirit of Laws, examples of federalist republics in corporate societies, the polis bringing together villages, and the cities themselves forming confederations. Federalism in the modern era was first adopted in the unions of states during the Old Swiss Confederacy.

A federation is a political 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.

There are six monarchies in Oceania where supreme power resides with an individual hereditary head, who is recognised as the head of state. Each is a constitutional monarchy, wherein the sovereign inherits his or her office, usually keeps it until death or abdication, and is bound by laws and customs in the exercise of their powers. Five of these independent states share King Charles III as their respective head of state, making them part of a global grouping known as the Commonwealth realms; in addition, all monarchies of Oceania are members of the Commonwealth of Nations. The only sovereign monarchy in Oceania that does not share a monarch with another state is Tonga. Australia and New Zealand have dependencies within the region and outside it, although five non-sovereign constituent monarchs are recognized by New Zealand, Papua New Guinea and France.
