A walk through the whole topic. What regionalism is, why it has grown, the organisations it has produced, the European Union up close, and the exam questions it all answers.
Most of the world's states now belong to a regional organisation. Some, like the European Union, have built a parliament, a court and a single market. Others, like the United States-Mexico-Canada Agreement, are little more than a trade deal. This walk-through takes the whole of Topic 5 in order: it explains what regionalism is, why states have turned to it, how seven regional organisations compare, what the EU has built that none of the others has, and how all of it is examined. Read it from the top, or use the topic-pack links at the end to revise a single part.
The starting definition, and the four forms the exam expects you to know. Scroll, and watch each form light up beside you.
Regionalism is the growth of cooperation, and of institutions, among states that share a geographical area. The specification definition is worth learning word for word: the creation and operation of institutions that express a shared identity and shape collective action within a geographical region. The key word is institutions. A one-off treaty is not regionalism. A standing body that keeps making decisions for its members, year after year, is.
One distinction runs through the whole topic, so it is worth fixing before anything else: how far do states actually hand power upwards? Scroll the diagram to set the four forms against that question.
Regionalism is more than neighbours trading. It is the point at which states build something that outlasts any single decision: a council, a court, a parliament, a market with common rules. The question every exam answer must reach is not whether states cooperate, but how much authority the institutions they build actually hold.
Two words sort every regional body. Intergovernmentalism is cooperation between states that each keep their sovereign independence: decisions need agreement, and any state can refuse. Supranationalism hands power to a body placed, in theory, above the state, so its decisions can bind members even against their will. When states agree to decide some things jointly through such a body, they use pooled sovereignty.
This is a separate question from the four forms below. Any form can be either intergovernmental or supranational: USMCA and the EU single market are both economic blocs, but USMCA stays intergovernmental while the EU single market is deeply supranational. Knowing the form does not tell you the depth - those are two independent axes, and a strong answer addresses both.
The most common form by far. States lower the barriers between their economies, moving from a free trade area, to a customs union with a common external tariff, to a single market in which goods, services, capital and people move freely. USMCA, Mercosur and the EU single market are the standard examples. Economic regionalism can be almost purely intergovernmental, as USMCA is, or deeply supranational, as the EU single market is.
States build shared institutions and speak with one voice, so that smaller members are heard in a world of great powers. The EU negotiates at the WTO as a single bloc; the African Union gives fifty-five states a common platform; the Arab League exists to safeguard the collective interests of Arab states. Political regionalism is where the sovereignty question bites hardest, because a common voice means agreeing a common position.
States cooperate against shared threats: external attack, terrorism, separatism, unstable borders. NATO is the clearest case of a security organisation, though it is trans-Atlantic rather than purely regional. The Shanghai Cooperation Organisation began as exactly this kind of body, with five states settling border disputes and coordinating against separatist movements before it widened its remit.
States group together to protect a shared regional identity and set of values, sometimes against the pull of a single global culture. ASEAN and its appeal to Asian values, expressed through the ASEAN Way of consensus, informality and non-interference, is the stock example. Cultural regionalism is usually the thinnest form, closer to a shared outlook than a set of binding rules.
Almost no real organisation is only one form. The EU is economic, political and increasingly a security actor at once; the African Union was built for political unity but runs a free trade area and peacekeeping missions. The mark of a strong answer is naming the form you are discussing and saying how far it has gone, rather than treating regionalism as one undivided thing.
Where ultimate authority lies, and how much sovereignty states give up. Scroll, and the two sides come into focus in turn.
The distinction between intergovernmental and supranational is about where ultimate authority lies, and how much sovereignty states actually give up. The figure beside you holds the two patterns side by side. Scroll, and each comes into focus in turn.
In an intergovernmental body, states cooperate but national governments remain fully sovereign and in control. Decisions are made by governments negotiating with each other, usually under a rule of unanimity or broad agreement, with vetoes commonly available. The institutions themselves are weak compared with the member governments, and policy depends on voluntary cooperation. A simple way to think of it: countries are working together, but nobody is above the state.
If NATO members discuss military action, each country still decides for itself whether to commit troops. NATO cannot force Britain or France to act. That is the intergovernmental pattern in one sentence: the alliance only does what the member states agree to do, and any of them can refuse. The same is true of the United Nations Security Council, where the five permanent members each hold a veto, and of much of the foreign policy side of the European Union.
In a supranational body, member states transfer some decision-making power to institutions placed above the nation state. Independent institutions can make binding decisions, majority voting may apply, and member states can be overruled. Rulings and rules can take precedence over national law. The states have not lost their sovereignty in those policy areas, but they have pooled it. A simple way to think of it: countries create a higher authority that can sometimes tell them what to do.
EU competition law can stop a member state from subsidising its own industries unfairly, even if that government wants to do so. The rule is set at EU level, the European Commission enforces it, and the European Court of Justice can fine the offending state if it does not comply. The member state cannot simply refuse, in the way it can refuse to commit troops to a NATO operation. That is supranational authority in action.
Set the two sides against each other and the difference is sharp. Intergovernmental: cooperation between sovereign states, governments dominate, vetoes common, sovereignty retained. Supranational: authority above states, independent institutions matter, majority voting possible, sovereignty pooled and shared. Whenever you analyse a regional body, place it on this contrast first.
The two-pattern picture is a starting point. In practice, supranationalism exists on a spectrum, not as an absolute category. Most international organisations are weak and intergovernmental, but a handful do carry real supranational features. The European Court of Human Rights, under the Council of Europe, makes binding judgments on states, though enforcement depends on member compliance. The World Trade Organization runs a dispute settlement system where states can be ruled against and usually comply, but it lacks broad law-making authority. The International Criminal Court prosecutes individuals for war crimes, even senior political leaders, though major powers such as the United States, China and Russia have limited or rejected its authority. Within the EU, the eurozone is itself highly supranational, because monetary policy is set centrally by the European Central Bank. NATO, at the other end, is overwhelmingly intergovernmental: members cooperate, but each decides for itself whether to act.
The European Union is the clearest and most developed supranational case, with directly binding law, a directly elected parliament, a court whose rulings can override national law, majority voting in many areas, a shared currency for most members, and independent institutions such as the European Commission and European Central Bank. Outside the EU, supranational features are typically narrow: issue-specific, dependent on state consent, weakly enforced, and without direct authority over individual citizens. The EU is closer to a partial federal system in some areas, which is why political scientists describe it as sui generis - a system of its own kind, without a close parallel. Among the regional bodies named in the specification, the EU is also the only one that is itself a hybrid: deeply supranational in trade law, competition policy and the role of the European Court of Justice, while remaining intergovernmental in taxation, defence and much of foreign policy. The nuance examiners reward is recognising where each body sits on the spectrum, not reaching for a single absolute label.
The economic and political pressures behind it, and its uneasy relationship with globalisation.
Modern, or "new", regionalism has grown fastest since the early 1990s. Several pressures explain it.
Economic opportunity. A larger shared market brings growth: lower trade barriers, more investment, shared technology. Most EU members have grown more prosperous inside the single market than they expect they would outside it.
Defence against the global economy. For weaker states, a bloc is a shield. Acting together, members can resist the pressure of transnational corporations, soften the policies of the Washington Consensus, and bargain harder at the World Trade Organization than any of them could alone. A regional bloc is a counterweight to the economic superpowers.
A bigger political voice. Politically, regionalism lets smaller states be heard. The EU negotiates at the WTO and the G20 as a unit roughly the size of the United States or China. The Arab League exists, in its own words, to safeguard the independence and interests of Arab states collectively.
Security and shared values. States also group together for security, as the Shanghai Cooperation Organisation did over shared borders and separatism, and to protect common values, as ASEAN does with the "ASEAN Way".
Underneath this sits the deepest theme of the topic: globalisation against state sovereignty. Every time states pool sovereignty in a regional body, they accept limits on their own authority. Whether that is a gain or a loss is the argument behind most of the exam questions in Part 7.
This debate gets a dedicated section next. The relationship between globalisation and regionalism is the single most-set framing on Paper 3 - so we open it out properly in Part 2.5 before moving on to the seven blocs.
The single most-set framing on Paper 3. Worth its own section because half the regionalism questions hang on it.
Paper 3 examiners come back to this debate almost every year. The 2021 sovereignty question, the 2023 mock "direct consequence of globalisation" question and most of the 12-mark comparatives turn on the same axis. The trap students fall into is treating it as a one-way relationship - either globalisation causes regionalism, or regionalism resists globalisation. The exam-rewarded answer is that both are true at the same time, and that different blocs sit at different points on the spectrum.
The strongest version of this reading is that regional blocs do not resist globalisation - they are the institutional form globalisation takes at the regional level. The end of the Cold War in 1991 and the founding of the WTO in 1995 created the conditions for a wave of new regional trade agreements designed to lock members into freer trade and capital movement.
Interim judgement on Reading 1. The chronology is telling. Almost every new regional body that matters today was created between 1991 and 2010, in the high-water years of globalisation. If regionalism were truly resistance, you would expect the timing to be different.
The opposite reading is that regional blocs exist precisely because globalisation overwhelms small or weak states acting alone. Pooling power into a regional body gives members a buffer against the forces they cannot individually resist - transnational corporations, financial volatility, the policy preferences of the IMF, World Bank and WTO, and the hard power of the United States and China.
Interim judgement on Reading 2. The "shield" reading is strongest when the bloc is built around states that would otherwise be price-takers in the global system. The weaker the individual member is on the world stage, the more the bloc looks like a defence rather than a vehicle.
The honest answer to the exam question is that the same bloc usually does both at once, on different policy areas. The EU is a vehicle for global integration on goods and capital but a shield on tech regulation, agricultural subsidies and climate standards. Mercosur was a vehicle on trade in the 1990s and a shield from 2010 onward. ASEAN is open-regionalist on trade but defensive on political values (the ASEAN Way of non-interference). USMCA is open-regionalist on capital flows but increasingly defensive on supply-chain rules versus China.
Useful test: if you replaced "regionalism" in the exam question with the word "the EU", would the answer be different? If yes, you have an EU-specific judgement, not a generic one. If no, you have generalised from the EU without checking the other blocs. The strongest answers do the comparison explicitly.
Scroll, and watch each region light up on the map and the comparison build below it. The exam board names five of these directly; two are wider examples.
Almost every part of the globe now sits inside a regional organisation. The map shows seven of them. As you scroll, each region lights up and the chart beneath records how deep that organisation's integration runs.
Five organisations are named in the specification: the EU, USMCA, the African Union, the Arab League and ASEAN. Learn these securely. They are lit on the map now.
The deepest and broadest of all. A single market, the euro, a directly elected Parliament, a supreme court, free movement of people, and a growing security role. The only body strongly supranational on almost every measure.
One green cell, four grey. The United States-Mexico-Canada Agreement, which replaced NAFTA in 2020, is purely economic - a trade agreement with no parliament, no court of its own and no political project.
Modelled roughly on the EU. It has an Assembly, a Commission, a Pan-African Parliament, the African Charter on Human and Peoples' Rights and a peacekeeping role. Broad but shallow: it reaches into every measure, but lightly.
The loosest of the five. Limited free trade, minimal shared institutions beyond its Council, and only occasional joint action. A political forum more than an integrated bloc. Its members span North Africa and the Middle East.
Strong on trade through the ASEAN Free Trade Area, but deliberately light on political institutions. The "ASEAN Way" of consensus and non-interference keeps it firmly intergovernmental, the opposite of the EU's approach.
Look at the five spec organisations together. Only the EU is deep across the board. The others are uneven - the AU broad but light, ASEAN economic-led, the Arab League loose, USMCA a single trade deal. "Regional organisation" covers all of this.
Not named in the spec, but a sharp comparison. An economic bloc with real institutions - a customs union with a common external tariff, plus a Council, an executive Group and a consultative Parliament. Deeper than USMCA, narrower than the EU.
Also a wider example. The mirror image of USMCA: security-led, not economic. Built to manage shared borders and resist what its members call outside interference in sovereign states.
Regionalism takes whatever form its members want. The EU stands alone in depth; everything else is partial and uneven. When a question says "regional organisations", a strong answer immediately asks which ones, and how deep?

Tap an organisation for the dates, members and features you can quote in an essay. The badge shows whether it is named in the specification.
Grew out of the European Coal and Steel Community (1951) and the European Economic Community, created by the Treaty of Rome (1957). The Maastricht Treaty (1992) created the EU itself; the Lisbon Treaty (2007) reformed it. It has 27 members after the UK left in 2020.
It is the only deeply supranational bloc: a single market with the "four freedoms" (goods, services, capital, people), a single currency used by most members (the euro), and binding institutions covered in Part 4. Membership requires signing the European Convention on Human Rights.
The United States-Mexico-Canada Agreement, which replaced NAFTA in 2020. The spec names it as NAFTA, now USMCA. It is mainly an economic organisation: a free trade agreement, not a political project.
Its notable feature is the sunset clause: the agreement must be reviewed periodically by all three nations, which keeps it under constant renegotiation rather than building permanent institutions.
Launched in 2002, replacing the Organisation of African Unity, and modelled in part on the EU. Its motto is "A united and strong Africa".
It has shared institutions (the Assembly, the Commission and a Pan-African Parliament), the African Continental Free Trade Area, the African Charter on Human and Peoples' Rights, and a peacekeeping role through the African Standby Force and missions such as AMISOM in Somalia. Broad ambitions, but most areas are still developing.
Founded in 1945 to draw closer the relations between Arab states and to safeguard their independence and sovereignty. Its members span North Africa and the Middle East.
It is the loosest of the named five: limited free trade (efforts towards the Greater Arab Free Trade Area), minimal shared institutions beyond its Council, and mainly political and diplomatic, rather than integrative, action.
The Association of Southeast Asian Nations. Economically integrated through the ASEAN Free Trade Area, but politically deliberately loose.
The ASEAN Way is the key term: consensus rather than majority voting, non-interference in members' internal affairs, informality, gradualism and mutual respect. This keeps ASEAN firmly intergovernmental and is sometimes linked to "Asian values" and to the criticism of regional egoism.
Not named in the specification, but a useful comparison. The Southern Common Market, founded by the Treaty of Asuncion (1991). Founding members: Argentina, Brazil, Paraguay and Uruguay. Venezuela joined in 2012 but has been suspended since 2016; Bolivia is in the process of joining.
It operates as a customs union with a common external tariff, and has real institutions: the Common Market Council, the Common Market Group and the consultative Parliament, Parlasur. It has negotiated trade agreements, including with the EU.
Not named in the specification, but a strong contrast. Began as the "Shanghai Five" in 1996 (China, Russia, Kazakhstan, Kyrgyzstan, Tajikistan), cooperating on shared borders and security. Uzbekistan joined in 2001, creating the SCO. India and Pakistan later became members.
It is a security and political body. Its members agreed that outside interference in sovereign territory, on the pretext of "humanitarian intervention", was unacceptable - a deliberate counterpoint to the Western idea of a Responsibility to Protect.
The one organisation deep enough to need a section of its own. Scroll through its institutions.
The EU is the case study at the heart of the topic, and the question is always how far it has moved from cooperation between states towards a government placed above them. Its institutions answer that question, because they split cleanly into two kinds: supranational bodies, which can act above the member states, and intergovernmental bodies, which keep power in the states' hands.
The diagram lists the five institutions you need to know. Green marks the supranational bodies, which can act above the member states; amber marks the intergovernmental bodies, which keep power with national governments. Scroll to take each one in turn.
Supranational. The Commission proposes EU law, enforces it, and prepares the EU budget. Each commissioner is nominated by a member government, but once in post they are bound to serve the EU as a whole and not their home state - which is exactly what makes the body supranational.
Supranational, and the only directly elected EU institution - voters in every member state elect their MEPs. It co-decides most legislation with the Council of the EU, has a say over the budget, and can accept or reject the Commission's nominees.
Supranational. The ECJ enforces EU law and settles disputes between member states, and its rulings bind national governments. A court that can overrule a member state is the clearest sign of pooled sovereignty in action.
Intergovernmental. This is the heads of government of the member states, meeting several times a year. It takes the big strategic decisions - the EU's direction, and whether to admit new members - and because it is the national leaders themselves, power stays with the states.
Intergovernmental. National ministers from the member states, meeting by policy area - agriculture, trade, the environment. Working with the Parliament, it decides whether to adopt legislation. Watch the trap: this is not the same body as the European Council in the step before.
This split is the EU debate in miniature. Where the EU decides by qualified majority voting, a state can be outvoted and power has moved upward. Where a national veto remains, the state is still in control. Subsidiarity - deciding at the lowest effective level - is the EU's promise that pooling sovereignty is not the same as losing it.
Widening and deepening. The EU has grown in two directions at once. Widening means taking in new members, through a series of enlargements from the original six to today's 27. Deepening means furthering integration into new areas - from a common market, to the single market, to monetary union and the euro. What drove this greater integration - the search for peace after 1945, shared prosperity, the pull of a large market, and the ambitions of the institutions themselves - is a standard exam line.
The EU as a global actor. Specification point 5.4 asks whether the EU has the power of a major country. Economically it is a heavyweight, roughly the size of the United States or China, and it negotiates as a single bloc at the WTO and in climate talks. It has a developing security role through the Common Security and Defence Policy. But it has no single army, no foreign policy it can always enforce, and 27 members who can pull in different directions. Whether that adds up to a superpower is the question behind several of the essays in Part 7.
Specification point 5.3. Scroll the timeline and watch European integration take shape, treaty by treaty.
The EU was not designed in one go. It grew over seventy years in two directions at once: widening, taking in new members, and deepening, pushing integration into new areas of policy. The timeline beside you sets out the milestones the exam expects you to know, in order. Watch the colour of each one: blue marks a widening, green a deepening.
European integration began as a way to make another European war impossible, and grew into the deepest experiment in regionalism anywhere in the world. It advanced on two tracks. Widening is the admission of new members; deepening is the extension of integration into new areas of policy. Almost every milestone on the timeline is one or the other.
In 1951 six states - France, West Germany, Italy, Belgium, the Netherlands and Luxembourg - placed their coal and steel industries under a shared High Authority. Tying together the raw materials of war was a deliberate peace project. The 1957 Treaty of Rome went further, creating the European Economic Community and a common market among the same six.
From those six the bloc grew in waves. The UK, Ireland and Denmark joined in 1973; Greece, Spain and Portugal followed in the 1980s as they returned to democracy; and in 2004 ten mostly post-communist states joined in the largest single enlargement. Widening spreads the EU's rules and market across the continent, but each new member also makes agreement among all of them harder.
The 1992 Maastricht Treaty is the turning point. It created the European Union itself, added cooperation on foreign policy and on justice to the existing common market, introduced EU citizenship, and set out the path to a single currency. This is deepening at its clearest: integration reaching well beyond trade.
Monetary union followed. The euro launched as an electronic currency in 1999, with notes and coins in 2002, and is now used by twenty member states. A shared currency removes a core power of the sovereign state, control of its own money, which is why the eurozone is often treated as the high-water mark of deepening.
An attempt to agree a full EU constitution collapsed when voters in France and the Netherlands rejected it in 2005. The 2007 Lisbon Treaty salvaged much of its content in a less ambitious form, streamlining decision-making, strengthening the European Parliament and creating a permanent President of the European Council.
Widening is not a one-way street. After a 2016 referendum, the United Kingdom left the EU in January 2020, the first member state ever to do so, and the EU went from twenty-eight members to twenty-seven. Brexit is the strongest evidence for the argument that sovereignty is pooled, not surrendered: a member state can take its powers back.
Widening and deepening pull against each other, and that tension is a ready-made exam line. A larger EU is harder to deepen, because twenty-seven governments must agree; a deeper EU is harder to widen, because the conditions of membership become more demanding. How far the EU should travel in either direction is the question behind specification point 5.3.
Specification point 5.5. Scroll through four global issues and see how far regionalism addresses each, and what it costs in sovereignty.
Specification point 5.5 asks how far regionalism addresses contemporary global issues. The honest answer is: unevenly. Some blocs do real work on conflict, poverty, rights and the environment; others barely touch them. Scroll through the four issues in turn, then weigh the cost.
Point 5.5 is a how far question, and the figure gives the short answer: on every issue, regionalism does something, but the EU does far more than the rest. Scroll through the four issues, then turn to what regionalism costs the states that take part.
Regional bodies do genuine security work. The African Union runs peacekeeping operations, including the long-running mission in Somalia, and the EU's Common Security and Defence Policy is slowly growing. But regional bodies also stall exactly where they are needed most: when their own members are divided, or when a member is itself the source of the conflict, the consensus that holds the bloc together also paralyses it.
A larger shared market can raise growth, attract investment and spread technology, and several blocs run development funds that move money toward poorer members. The EU's structural funds are the clearest example. But the gains are uneven: integration can also concentrate industry and investment in the richer members, widening the gap it was meant to close.
Here the contrast is sharpest. The EU makes respect for human rights a genuine condition of membership, backed by the European Convention on Human Rights. The African Union has its Charter on Human and Peoples' Rights. But ASEAN's human rights declaration is weakly enforced and cuts against its non-interference rule, and the Shanghai Cooperation Organisation actively resists outside human-rights pressure as interference in sovereign affairs.
The EU has been one of the most consistent voices in global climate negotiations, setting binding internal targets and negotiating as a single bloc. Purely economic blocs such as USMCA do very little, because tackling climate change means common rules and shared costs, exactly the supranational commitment those blocs were designed to avoid.
Every gain from regionalism is paid for in sovereignty. Critics argue regional bodies erode the state, because binding courts, majority voting and common rules all limit what a national government can decide. Supporters reply that sovereignty is pooled, not lost: states gain more collective power than they give up, and they can leave. This is the trade the exam wants weighed, not just described.
A fair conclusion holds two things together. Regionalism makes global governance more manageable, because agreement among a few large blocs is easier than agreement among more than 190 separate states. But it can also let blocs assert regional interests against global rules, as when the African Union discouraged cooperation with the International Criminal Court. Regionalism is a partial answer to global problems: strongest in the EU, and patchy almost everywhere else.
The questions this topic is examined through, and how the walk-through feeds them.
Paper 3 Global examines this topic as a 12-mark comparative question (Section A) and a 30-mark essay (Q3). These are real recent questions. Tap one for how to use the walk-through to answer it.
Trap: "eroded" - measure how much sovereignty is actually lost, and define pooled sovereignty first. Use the chart: the EU's binding court and majority voting are the strong "for" case; USMCA, ASEAN and the Arab League, which stay intergovernmental, are the "against" case. Conclude that erosion depends entirely on which bloc you mean.
Trap: define superpower across economic, political, structural and military power. Part 4's "global actor" material is the spine: economically yes, militarily no, politically only when members agree.
Trap: a comparison - regional bodies set against the economic institutions of global governance. Part 6 supplies the regional side; weigh the EU and AU against the global lenders, issue by issue.
Trap: "direct consequence" overstates it. Part 2's tension is the whole answer: regionalism is partly driven by globalisation and partly a defence against it.
Trap: the sovereignty-against-pooling debate again. Use small EU states, which gain a global voice, against the argument that membership constrains national choice.
Approach: a 12-mark comparative answer, and both organisations are named in the spec. Pair them on shared features - both bring many states into a union with common aims, both began with an economic focus and moved into political and security roles, both built parliaments and courts.
Approach: Part 2 is written for this question. Pair economic factors (larger markets, defence against the global economy) with political factors (a bigger voice, shared values), with a named bloc for each.
Three directly comparative themes - each pits one set of blocs or one understanding of sovereignty against another, so the comparative spine of Paper 3 runs through every paragraph.
Other comparative themes you could substitute: economic against political regionalism (USMCA against EU on the same axis); regional bloc against global IGO as the more significant erosion (EU against IMF / WTO); founding members against later joiners (EU 6 against post-2004 entrants); EU as global actor against EU as union (whether sovereignty erosion is the price of collective power on the world stage).
The two other 30-mark questions the examiners are most likely to ask in this area. Each is laid out as a plan rather than a full essay so you can read the structure quickly and write the prose yourself.
Three directly comparative themes - each weighs the defence reading against the vehicle reading so the synoptic spine of the question runs through every paragraph.
Substitute themes: commodity blocs (OPEC, Mercosur) against trade blocs (USMCA, ASEAN); founding decade (1991-2010) against second wave (post-2015); economic blocs against security blocs (SCO, NATO) where security regionalism is more clearly defensive.
Three directly comparative themes - each weighs the EU against a named alternative so the comparison is built into the structure.
Substitute themes: peace as success (EU's founding aim against Mercosur's post-1991 democratic consolidation); economic growth as success (single market against ASEAN's export miracle); soft power and global voice as success (EU as global actor against AU's growing UN influence).
The vocabulary the examiner expects you to define and use.
Regionalism - creation and operation of institutions that express a shared identity and shape collective action within a geographical region.
European Union - a political and economic union of 27 (formerly 28) member states in Europe.
European integration - the process of industrial, political, legal, economic, social and cultural integration of states in Europe.
Sovereignty - absolute and unlimited power and authority.
Supranationalism - power given to an authority placed, in theory, above the state.
Intergovernmentalism - interaction among states based on sovereign independence.
Pooled sovereignty - states agreeing to take some decisions jointly through a shared body for mutual benefit.
Global actor - an entity that participates in international relations.
Widening and deepening - the process by which the EU has expanded membership while furthering integration.
Qualified majority voting (QMV) - EU voting where a state can be outvoted; a supranational feature.
National veto - a member state's power to block a decision; an intergovernmental feature.
Subsidiarity - the principle that decisions are taken at the lowest effective level.
Federalism - a system in which power is divided between central and regional levels.
Regional egoism - a bloc putting its own regional interests above wider global cooperation.
Regional hegemony - the dominance of one powerful state within a regional bloc.
