{{Forms of government}}
A '''federation''' (also called a '''federal state''') is an entity characterized by a [[political union|union]] of partially [[federated state|self-governing provinces, states, or other regions]] under a [[#Federal governments|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 [[constitution]]ally entrenched and may not be altered by a unilateral decision, neither by the component states nor the federal political body without constitutional amendment.

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.<ref>{{Cite web |title=Federalism and Federation |url=https://pesd.princeton.edu/node/431 |access-date=2024-01-24 |website=The Princeton Encyclopedia of Self-Determination |language=en}}</ref>

Overriding powers of a central authority theoretically can 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"{{citation needed|date=May 2024}} 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 [[federalism]]. It can be considered in comparison with the [[unitary state]]. [[France]] and [[Japan]], for example, have been unitary for many centuries.
The [[Austrian Empire]] was a unitary state with [[Crown lands#Austria|crown lands]]; after the transformation into the [[Austria-Hungary]] monarchy, the remaining crown lands of so-called [[Cisleithania]] became federated as ''[[States of Austria|Länder]]'' of the [[Republic of Austria]] through the implementation of [[Constitution of Austria|its constitution]]. [[Germany]], with its 16 [[states of Germany|states, or ''Länder'']], and [[Nigeria]], with its 36 [[states of Nigeria|states]] and [[Federal Capital Territory (Nigeria)|federal capital territory]], are examples of federations. Federations are often [[ethnic group|multi-ethnic]] and cover a large area of territory (such as [[Russia]], the [[United States]], [[Canada]], [[India]], [[Brazil]], [[Pakistan]] or [[Australia]]), but neither is necessarily the case (such as [[Saint Kitts and Nevis]] or the [[Federated States of Micronesia]]).<ref>{{Cite book |last=Anderson |first=George |url=https://forumfedorg.b-cdn.net/wp-content/uploads/2016/02/Federalism-pdf-to-press.pdf |title=Federalism: an introduction |date=28 July 2008 |publisher=Oxford Univ.

==History==
Several ancient chiefdoms and kingdoms, such as the 4th-century-BCE [[League of Corinth]], [[Noricum]] in [[Central Europe]], and the [[Iroquois|Iroquois Confederacy]] in [[pre-Columbian North America]], could be described as federations or [[confederation]]s. The [[Old Swiss Confederacy]] was an early example of formal non-unitary statehood.{{citation needed|date=August 2023}}

Several colonies and dominions in the [[New World]] consisted of autonomous provinces, transformed into federal states upon independence such as the [[United States]], and various countries in [[Latin America]] (see [[Spanish American wars of independence]]). Some of the New World federations failed; the [[Federal Republic of Central America]] broke up into independent states less than 20 years after its founding. Others, such as [[Argentina]], have shifted between federal, [[Confederation|confederal]], and unitary systems, before settling into federalism. [[Brazil]] became a federation only after the fall of [[Brazilian Empire|the monarchy]], and [[Venezuela]] became a federation after the [[Federal War]].

[[Australia]] and [[Canada]] are also federations. They became federations while still part of the British Empire, and gradually evolved towards full independence.

[[Germany]] is another [[nation-state]] that has switched between confederal, federal and unitary rules, since the [[German Confederation]] was founded in 1815. The [[North German Confederation]], the succeeding [[German Empire]] and the [[Weimar Republic]] were federations.

Founded in 1922, the [[Soviet Union]] was formally a federation of [[republics of the Soviet Union|Soviet republics]], [[Autonomous Soviet Socialist Republics of the Soviet Union|autonomous republics]] and other federal subjects, though in practice highly centralized under the [[government of the Soviet Union]]. The [[Russia|Russian Federation]] has inherited a similar system.

[[India]], [[Pakistan]], [[Nigeria]] and [[Malaysia]] (then [[Federation of Malaya]]) became federations on or shortly before becoming independent from the [[British Empire]].

In some recent cases, federations have been instituted as a measure to handle [[ethnic conflict]] within a state, such as [[Bosnia and Herzegovina]], and [[Federalism in Iraq|Iraq since 2005]] as well as [[Somalia|Somalia since 2012]].

With the [[United States Constitution]] having become effective on 4 March 1789, the [[United States]] is the oldest surviving federation, while the newest federation is [[Nepal]], after its [[Constitution of Nepal 2015|constitution]] went into effect on 20 September 2015.

===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 [[international law]]. However, [[States of Germany|German Länder]] have that power,<ref>{{Cite journal | last1 = Leonardy | first1 = U. | title = Federation and Länder in German foreign relations: Power-sharing in treaty-making and European affairs | doi = 10.1080/09644009208404305 | journal = German Politics | volume = 1 | issue = 3 | pages = 119–135 | year = 1992 }}</ref> which is beginning to be exercised on a European level.

Some federations are called [[asymmetric federation|asymmetric]] because some states have more autonomy than others. An example of such a federation is [[Malaysia]], in which [[Sarawak]] and [[Sabah]] agreed to form the federation on different terms and conditions from the states of [[Peninsular Malaysia]].<ref>{{Cite web |last=Harding |first=Andrew |date=2021-01-25 |title=Asymmetric Federalism and Protection of Indigenous Peoples: The Case of Sabah and Sarawak in Malaysian Federalism |url=https://50shadesoffederalism.com/case-studies/asymmetric-federalism-and-protection-of-indigenous-peoples-the-case-of-sabah-and-sarawak-in-malaysian-federalism/ |access-date=2024-01-24 |website=50 Shades of Federalism |language=en-GB}}</ref>

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|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 (state)|Tocantins]], was created by the [[1988 Brazilian Constitution|1988 Constitution]] for chiefly administrative reasons.

Seven of the top eight [[list of countries and outlying territories by total area|largest countries by area]] are governed as federations.<!-- Would it be safe to say here that Federalism is often associated with large countries? Probably Original Research... -->

===Unitary states===
A [[unitary state]] 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".

===Confederation===
[[File:Carte suisse2.png|thumb|upright=1.1|The [[Swiss Confederation]] and its [[Cantons of Switzerland|26 cantons]]]]
A [[confederation]], in modern political terms, is usually limited to a permanent union of sovereign states for common action in relation to other states.<ref>{{cite OED|confederation}}</ref> The closest entity in the world to a confederation at this time is the [[European Union]]. 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 [[Switzerland as a federal state|lost their sovereign status]] in 1848.<ref>[http://www.swissworld.org/en/politics/general_information/ch_confoederatio_helvetica/ CH: Confoederatio Helvetica - Switzerland - Information] {{Webarchive|url=https://web.archive.org/web/20150330035550/http://www.swissworld.org/en/politics/general_information/ch_confoederatio_helvetica/ |date=30 March 2015 }}. Swissworld.org. Retrieved on 2013-07-12.</ref>

In Belgium, however, the opposite movement is underway.<ref name="Lagasse">One of the most important recent books about the Belgian institutions, written by one of the leading French-speaking jurists{{who|date=April 2014}} 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 {{ISBN|2-87127-783-4}}</ref> 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 [[Confederation#Belgium|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.<ref name="Belgium">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.</ref>

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 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 US in the wake of the Civil War of the latter, use the term [[Canadian Confederation|"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.

===Empire===
An [[empire]] is a multi-ethnic state, [[multinational state]], or a group of nations with a [[central government]] established usually through [[coercion]] (on the model of the [[Roman Empire]]). 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 [[emperor]] or senior king ([[great king]], [[high king]], [[king of kings]]...). One example of this was the [[German Empire]] (1871–1918).

===Comparison with other systems of autonomy===

====Federacy====
A [[federacy]]<ref>Some dictionaries, such as the Webster's Encyclopedic Unabridged Dictionary of the English Language (1989 ed.), state that federacy is synonymous with confederacy ("by aphesis"). In French, the English words federacy, confederacy, and confederation are all translated by "confédération".</ref> is a unitary state that incorporates one or more self-governing [[autonomous area]]s. It is distinguished from a federation in that the constitutional structure of the state is still unitary, but incorporates federalist principles. Some federacies, notably [[Åland]], were established through [[international treaty]].

====Devolution====
A federation differs from a [[devolution|devolved state]], such as [[Indonesia]] and the United Kingdom, because, in a devolved state, the central government can revoke the independence of the subunits (the [[Scottish Parliament]], the [[Welsh Parliament]] and the [[Northern Ireland Assembly]] in the case of the United Kingdom) without changing the constitution. In some cases, such as the [[autonomous communities of Spain]], devolution has led to federation in all but name, or "federation without federalism".<ref name="Spain Xavier Arbós Marín page 375">The Federal Option and Constitutional Management of Diversity in Spain Xavier Arbós Marín, page 375; included in 'The Ways of Federalism in Western Countries and the Horizons of Territorial Autonomy in Spain' (volume 2), edited by Alberto López-Eguren and Leire Escajedo San Epifanio; edited by [[Axel Springer SE|Springer]] {{ISBN|978-3-642-27716-0}}, {{ISBN|978-3-642-27717-7}}(eBook)</ref>

====Crown dependencies====
The relation between the [[Crown Dependencies]] of the [[Isle of Man]] and the bailiwicks of [[Guernsey]] and [[Jersey]] in the [[Channel Islands]] and the United Kingdom is very similar to a federate relation: the Islands enjoy independence from the United Kingdom, which, via The Crown, takes care of their foreign relations and defense&nbsp;– although the UK Parliament does have overall power to legislate for the dependencies. However, the islands are neither an incorporated part of the United Kingdom nor are they considered to be independent or associated states. The islands do not have a monarch, ''per se''; rather in the Isle of Man the [[Monarchy of the United Kingdom|British Monarch]] is, ''[[ex officio]]'', [[Lord of Mann]], and in the Bailiwicks of Guernsey and Jersey, the [[Monarchy of the United Kingdom|British Monarch]] rules as the [[Duke of Normandy]].

====Dependent territories====
[[Dependent territory|Dependent territories]], such as the [[British overseas territories]], are vested with varying degrees of power; some enjoy considerable independence from the sovereign state, which only takes care of their foreign relations and defense. However, they are neither considered to be part of it nor recognized as sovereign or associated states.

===''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.<ref>{{cite journal|url = https://www.qmul.ac.uk/law/media/law/docs/undergrad/13-Sahadzic.pdf|title = Federal Theory on Constitutional Asymmetries: revisited|first = Maja|last = Sahadzic|journal = Queen Mary Law Journal|pages = 135–147|access-date = 26 February 2019|archive-date = 27 February 2019|archive-url = https://web.archive.org/web/20190227060720/https://www.qmul.ac.uk/law/media/law/docs/undergrad/13-Sahadzic.pdf|url-status = dead}}</ref>

''De facto'' federations, or quasi-federations, are often termed "[[regional state]]s".

====South Africa====
[[File:Map of South Africa with English labels.svg|thumb|Provinces of South Africa]]
Although South Africa bears some elements of a federal system, such as the allocation of certain powers to provinces, some nevertheless argue that it is functionally a unitary state.<ref>{{cite web|url=https://www.researchgate.net/publication/261213778|title=The type of government in the Republic of South Africa - Examining the presence of federal and unitary state elements in the republic|last1=Wright|first1=Jonathan Haydn Faure|date=31 March 2014|website=www.researchgate.net|access-date=8 November 2016|quote=After careful research and analysis of various sources and the constitution, it can be confirmed that the government system in the Republic of South Africa is a unitary system.

====European Union====
{{Original research|section|date=March 2017}}
{{Update|type=section|the three pillars|date=June 2011}}
The [[European Union]] (EU) is a [[sui generis]] [[political union]] or confederation (the assemblage of societies or an association of two or more states into one state).<ref>"Federalist Paper No. 9", p. 70 Alexander Hamilton</ref> [[Robert Schuman]], the initiator of the European Community system, wrote that a [[Transnational governance|transnational]] Community like the founding of the [[European Coal and Steel Community]] lay midway between an association of States where they retained complete independence and a federation leading to a fusion of States in a [[superstate|super-state]].<ref>''La Communaute du Charbon et de l'Acier'', p7 Paul Reuter with a preface by Robert Schuman. Paris 1953.</ref> The [[Founding fathers of the European Union|Founding Fathers of the European Union]] wrote the [[Europe Declaration|Europe Declaration (Charter of the Community)]] at the time of the signing of the [[Treaty of Paris (1951)|Treaty of Paris]] on 18 April 1951 saying that Europe should be organized on a transnational foundation. They envisaged a structure quite different from a federation called the [[European Political Community (1952)|European Political Community]].{{Citation needed|date=April 2010}}

The EU is a three-pillar structure of the original supranational [[European Economic Community]] and the nuclear energy cooperation and non-proliferation treaty, [[Euratom]], plus two largely [[intergovernmentalism|intergovernmental]] pillars dealing with External Affairs and Justice and Home Affairs. The EU is therefore not a ''[[De facto#De jure|de jure]]'' federation, although some{{who|date=April 2014}} academic observers conclude that after 50 years of institutional evolution since the [[Treaties of Rome]] it is ''becoming'' one.<ref>{{Cite journal | last1 = Josselin | first1 = J.

However, its central government is far weaker than that of most federations and the individual members are sovereign states under international law, so it is usually characterized as an unprecedented form of supra-national union. The EU has responsibility for important areas such as trade, monetary union, agriculture, and fisheries. Nonetheless, EU [[Member State of the European Union|member state]]s retain the right to act independently in matters of foreign policy and defense, and also enjoy a near-monopoly over other major policy areas such as criminal justice and taxation. Since the [[Treaty of Lisbon]], the Member States' right to leave the Union is codified, and the Union operates with more [[qualified majority voting]] (rather than unanimity) in many areas.{{Citation needed|date=April 2010}}

====People's Republic of China====
{{main|Federalism in China}}
Constitutionally, the power vested in the [[Special Administrative Region of the People's Republic of China|special administrative region]]s of the People's Republic is granted from the [[Central People's Government]], through a decision by the [[National People's Congress]]. However, there have been certain largely informal grants of power to the provinces, to handle economic affairs and implement national policies, resulting in a system some have termed federalism "[[with Chinese characteristics]]".<ref>{{Cite journal |ssrn=1151187|title=Economic Warlords: How De Facto Federalism Inhibits China's Compliance with International Trade Law and Jeopardizes Global Environmental Initiatives |author=Gregory H. Fuller |journal=Tennessee Law Review |volume=75 |page=545 |year=2008}}</ref>

====Myanmar====
Constitutionally a [[unitary state]], the political system in Myanmar bears many elements of federalism. Each [[administrative divisions of Myanmar|administrative division]] has its own cabinets and chief ministers, making it more like a federation rather than a unitary state.

====Wallis and Futuna====
The [[France|French]] [[overseas collectivity]] [[Wallis and Futuna]] maintains some quasi-federation attributes. The territory is divided into three traditional chiefdoms: [[Uvea (Wallis and Futuna)|Uvea]], [[Sigave]], and [[Alo (Wallis and Futuna)|Alo]]. The chiefdoms are allowed to have their own [[legal custom|legal system]] which have to be implemented along with [[Law of France|French legal system]].

==Internal controversy and conflict==
{{Unreferenced section|date=October 2024}}
[[File:CentralAmerica1860MapSmall.jpg|thumb|right|upright=1.1|The [[United Provinces of Central America]] was a short-lived federal republic.]]

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]], 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–[[Bleeding Kansas|Kansas Territory]]), in [[Nigeria]] and in [[Switzerland]]. In the case of [[Malaysia]], [[Singapore]] was expelled from the federation because of rising racial tension. In some cases, internal conflict may lead a federation to collapse entirely, as occurred the [[Federation of Rhodesia and Nyasaland]], the [[Gran Colombia]], the [[United Provinces of Central America]], and the [[West Indies Federation]].

==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 varies. Based on a broad definition of a basic [[federalism]], 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 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.<ref name="Gttsdpc">{{cite web|title=Guidebook to the Somali Draft Provisional Constitution|url=http://unpos.unmissions.org/LinkClick.aspx?fileticket=v067edqd7a8%3D&tabid=9705&language=en-US|access-date=2 August 2012|url-status=dead|archive-url=https://web.archive.org/web/20130120021547/http://unpos.unmissions.org/LinkClick.aspx?fileticket=v067edqd7a8%3D&tabid=9705&language=en-US|archive-date=20 January 2013}}</ref>
