A 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 (

). 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 typically
constitutionally entrenched and may not be altered by a unilateral decision, neither by the component states nor the federal political body. Alternatively, a federation is a form of government in which sovereign power is formally divided between a central authority and a number of constituent regions so that each region retains some degree of control over its internal affairs.
It is often argued that federal states where the central government has overriding powers are not truly federal states. For example, such overriding powers may include: the constitutional authority to suspend a constituent state's government by invoking gross mismanagement or civil unrest, or to adopt national legislation that overrides or infringes on the constituent states' powers by invoking the central government's constitutional authority to ensure "peace and good government" or to implement obligations contracted under an international treaty.
The governmental or constitutional structure found in a federation is considered to be federalist, or to be an example of

Federations and other forms of state
Federations
The component states are in some sense sovereign, insofar as certain powers are reserved to them that may not be exercised by the central government. However, a federation is more than a mere loose alliance of independent states. The component states of a federation usually possess no powers in relation to foreign policy and so enjoy no independent status under

.
A federation often emerges from an initial agreement between several separate states. The purpose can be the will to solve mutual problems and to provide for mutual defense or to create a
nation-state for an ethnicity spread over several states. The former was the case with the United States and Switzerland. However, as the histories of countries and nations vary, the federalist system of a state can be quite different from these models. Australia, for instance, is unique in that it came into existence as a nation by the democratic vote of the citizens of each state, who voted "yes" in referendums to adopt the
Australian Constitution. Brazil, on the other hand, has experienced both the federal and the unitary state during its history. Some present-day states of the Brazilian federation retain borders set during the Portuguese colonization (before the very existence of the Brazilian state), whereas the latest state,
Tocantins, was created by the
1988 Constitution for chiefly administrative reasons.
Seven of the top eight
largest countries by area are governed as federations.
Unitary states
A
unitary state
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 th ...
is sometimes one with only a single, centralized, national tier of government. However, unitary states often also include one or more self-governing regions. The difference between a federation and this kind of unitary state is that in a unitary state the autonomous status of self-governing regions exists by the sufferance of the central government, and may be unilaterally revoked. While it is common for a federation to be brought into being by agreement between a number of formally independent states, in a unitary state self-governing regions are often created through a process of devolution, where a formerly centralized state agrees to grant autonomy to a region that was previously entirely subordinate. Thus, federations are often established voluntarily from "below" whereas devolution grants self-government from "above".
It is often part of the philosophy of a unitary state that, regardless of the actual status of any of its parts, its entire territory constitutes a single sovereign entity or
nation-state, and that by virtue of this the central government exercises sovereignty over the whole territory ''as of right''. In a federation, on the other hand, sovereignty is often regarded as residing notionally in the component states, or as being shared between these states and the central government.
Confederation

A
confederation, in modern political terms, is usually limited to a permanent union of sovereign states for common action in relation to other states. The closest entity in the world to a confederation at this time is the
European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been ...
. While the word ''confederation'' was officially used when the Canadian federal system was established in 1867, the term refers only to the process and not the resulting state since Canadian provinces are not sovereign and do not claim to be. In the case of
Switzerland, while the country is still known officially as the Swiss Confederation, this is now a misnomer since the Swiss cantons
lost their sovereign status in 1848.
In Belgium, however, the opposite movement is underway.
[One of the most important recent books about the Belgian institutions, written by one of the leading French-speaking jurists concludes: ''Vers le confédéralisme'' (Toward a Confederation). See: Charles-Etienne Lagasse, ''Les Nouvelles institutions politiques de la Belgique et de l'Europe'', Erasme, Namur 2003, p. 603 ] Belgium was founded as a centralized state, after the French model, but has gradually been reformed into a federal state by consecutive constitutional reforms since the 1970s. Moreover, although nominally called a federal state, the country's structure already has a number of
confederational traits. At present, there is a growing movement to transform the existing federal state into a looser confederation with two or three constitutive states and/or two special regions.
[Many Flemings would prefer two states, Flanders and Wallonia, and two special regions, Brussels and the German-speaking region. In Wallonia, there is wider support for three states: Flanders, Wallonia and Brussels.]
A confederation is most likely to feature three differences when contrasted with a federation: (1) No real direct powers: many confederal decisions are externalized by member-state legislation; (2) Decisions on day-to-day-matters are not taken by simple majority but by special majorities or even by consensus or unanimity (veto for every member); (3) Changes of the constitution, usually a treaty, require unanimity.
Over time these terms acquired distinct connotations leading to the present difference in definition. An example of this is the United States under the
Articles of Confederation
The Articles of Confederation and Perpetual Union was an agreement among the 13 Colonies of the United States of America that served as its first frame of government. It was approved after much debate (between July 1776 and November 1777) by ...
. The Articles established a national government under what today would be defined as a federal system (albeit with a comparatively weaker federal government). However, Canadians, designed with a ''stronger'' central government than the U.S. in the wake of the Civil War of the latter, use the term
"Confederation" to refer to the formation or joining, not the structure, of Canada. Legal reforms, court rulings, and political compromises have ''decentralized'' Canada in practice since its formation in 1867.

). An empire often includes self-governing regions, but these will possess autonomy only at the sufferance of the central government. On the other hand, a political entity that is an empire in name, may comprise several partly autonomous kingdoms organised together in a federation, with the empire being ruled over by an

''De facto'' federations
The distinction between a federation and a unitary state is often quite ambiguous. A unitary state may closely resemble a federation in structure and, while a central government may possess the theoretical right to revoke the autonomy of a self-governing region, it may be politically difficult for it to do so in practice. The self-governing regions of some unitary states also often enjoy greater autonomy than those of some federations. For these reasons, it is sometimes argued that some modern unitary states are ''de facto'' federations.
''De facto'' federations, or quasi-federations, are often termed "
regional states".

The EU has responsibility for important areas such as trade, monetary union, agriculture, fisheries. Nonetheless, EU

Internal controversy and conflict

Certain forms of political and constitutional dispute are common to federations. One issue is that the exact division of power and responsibility between federal and regional governments is often a source of controversy. Often, as is the case with the
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 U.S. state, states, a Washington, D.C., federal district, five ma ...
, such conflicts are resolved through the judicial system, which delimits the powers of federal and local governments. The relationship between federal and local courts varies from nation to nation and can be a controversial and complex issue in itself.
Another common issue in federal systems is the conflict between regional and national interests, or between the interests and aspirations of different ethnic groups. In some federations the entire jurisdiction is relatively homogeneous and each constituent state resembles a miniature version of the whole; this is known as 'congruent federalism'. On the other hand,
incongruent federalism exists where different states or regions possess distinct ethnic groups.
The ability of a federal government to create national institutions that can mediate differences that arise because of linguistic, ethnic, religious, or other regional differences is an important challenge. The inability to meet this challenge may lead to the secession of parts of a federation or to civil war, as occurred in the United States (southern states sought to protect the institution of slavery while northern states opposed it, with a catalysis occurring in the then–
Kansas Territory), in

Federal governments
The federal government is the common government of a national or
supranational federation. A federal government may have distinct powers at various levels authorized or delegated to it by its member states. The structure of federal governments vary. Based on a broad definition of a basic
federalism
Federalism is a combined or compound mode of government that combines a general government (the central or "federal" government) with regional governments (provincial, state, cantonal, territorial, or other sub-unit governments) in a single po ...
, there are two or more levels of government that exist within an established territory and govern through common institutions with overlapping or shared powers as prescribed by a constitution.
The federal government is the government at the level of the sovereign state. Usual responsibilities of this level of government are maintaining
national security and exercising international diplomacy, including the right to sign binding
treaties. Basically, a modern federal government, within the limits defined by its constitution, has the power to make laws for the whole country, unlike local governments. As originally written, the
United States Constitution was created to limit the federal government from exerting power over the states by enumerating only specific powers. It was further limited by the addition of the
Tenth Amendment
The Tenth Amendment (Amendment X) to the United States Constitution, a part of the Bill of Rights, was ratified on December 15, 1791. It expresses the principle of federalism, also known as states' rights, by stating that the federal governmen ...
contained in the
Bill of Rights and the
Eleventh Amendment. However, later amendments, particularly the
Fourteenth Amendment, gave the federal government considerable authority over states.
Federal government within this structure are the government ministries and departments and agencies to which the ministers of government are assigned.
