The European Union (EU) is a supranational economic and political union of 27 European countries that sets common policies its members must follow; in AP Comp Gov it shows up mainly through the United Kingdom, whose 2016 Brexit referendum let citizens vote directly on leaving the EU.
The European Union is a group of 27 European countries that agreed to make certain decisions together instead of separately. Member states keep their own governments, but they hand over real authority on things like trade rules and common policies to EU institutions. That's what makes the EU supranational. Its rules sit above national governments, which is a big deal in a course built around state sovereignty.
For AP Comp Gov, you don't need to memorize EU institutions in detail. What you need is the UK angle. The United Kingdom joined the EU's predecessor in 1973, grew increasingly divided over how much power Brussels should have, and in 2016 held a national referendum on whether to leave. Voters chose to exit (Brexit), and the UK formally left in 2020. That referendum is the course's go-to example of direct democracy and a major case of citizens using formal political participation to force a massive policy change.
The EU lives in Unit 3: Political Culture and Participation, specifically Topic 3.5 (Nature and Role of Political Participation), supporting learning objective AP Comp Gov 3.5.A. The CED says participation can range from supportive behavior to oppositional behavior that seeks to change government policy (DEM-1.A.2). Brexit is the textbook case. UK citizens didn't riot or overthrow anything. They used a formal, legitimate channel (a referendum) to overturn decades of national policy. The EU also threads into the course's bigger sovereignty story, since joining a supranational organization means a state voluntarily gives up some control over its own policies. That tension between national sovereignty and supranational authority is exactly why the Brexit vote happened.

Supranationalism (Units 1 & 5)
The EU is the example of supranationalism in this course. When the UK joined, EU rules could override British law in certain areas, which clashed with the UK's tradition of parliamentary sovereignty. 'Take back control,' the Leave campaign's slogan, was basically an argument about sovereignty.
Single Market (Unit 5)
The single market is the EU's economic engine. It lets goods, services, money, and people move freely across member borders. Free movement of people was one of the most contested issues driving the Brexit vote, which is how an economic policy turned into a participation story.
Eurozone (Unit 5)
The Eurozone is the subset of EU members that use the euro as their currency. The UK was in the EU but never adopted the euro, which tells you something on its own. The UK always kept the EU at arm's length, and that ambivalence eventually produced Brexit.
Referenda and Direct Democracy (Unit 3)
The 2016 Brexit vote is the course's clearest example of a referendum in action. Instead of Parliament deciding, the question went straight to citizens. That makes it direct democracy operating inside a system that normally runs on representative democracy.
The EU almost always appears on the exam attached to the UK, not as a standalone topic. Multiple-choice questions typically describe the 2016 Brexit referendum and ask you to identify what it illustrates, such as direct democracy, a function of referenda, or formal political participation under AP Comp Gov 3.5.A. Practice questions in this style ask things like 'How did the UK use referenda in relation to the European Union?' No released FRQ has centered on the EU by name, but it's strong evidence for conceptual and argument questions about participation, sovereignty, or how global forces shape domestic politics. Your job is to use it correctly. If a question asks for an example of citizens directly deciding a major policy question, Brexit is your answer.
The EU and the Eurozone are not the same thing. The EU is the full political and economic union of 27 countries. The Eurozone is only the members that use the euro as their currency. The UK proves the difference matters. It belonged to the EU for decades but always kept the British pound, so it was in the EU but never in the Eurozone. If an exam question is about currency, it's a Eurozone question. If it's about policy, sovereignty, or Brexit, it's an EU question.
The European Union is a supranational economic and political union of 27 European countries, meaning member states give up some sovereignty to follow common EU policies.
In AP Comp Gov, the EU matters mostly through the United Kingdom and the 2016 Brexit referendum, in which citizens voted directly to leave the EU.
The Brexit referendum is the course's go-to example of direct democracy and of formal political participation changing government policy (Topic 3.5, AP Comp Gov 3.5.A).
The EU and the Eurozone are different. The UK was an EU member for decades but never adopted the euro.
EU membership creates a sovereignty tradeoff, and that tension between national control and supranational authority is exactly what drove the Brexit vote.
The UK formally left the EU in 2020, four years after the referendum, showing that a referendum result can take years to fully implement.
The EU is a supranational economic and political union of 27 European countries that sets common policies its members follow. In AP Comp Gov it's tested mainly through the UK, especially the 2016 Brexit referendum as an example of direct democracy and political participation.
No. The six course countries are the UK, Russia, China, Iran, Mexico, and Nigeria. The EU only appears because of its relationship with the UK, especially Brexit, so study it through that lens.
No. UK citizens voted to leave in the 2016 referendum, and the UK formally exited the EU in 2020. For exam purposes, treat the UK as a former EU member whose departure illustrates how referenda work.
The EU is the full union of 27 member countries, while the Eurozone is only the members that use the euro as their currency. The UK belonged to the EU but kept the pound, so it was never part of the Eurozone.
Because the 2016 referendum let citizens decide a major policy question directly instead of leaving it to Parliament. That makes it a clear example of direct democracy and of formal participation aimed at changing government policy, which is exactly what AP Comp Gov 3.5.A covers.
