If you don't know anything (or know very little) about the European Union, here are a couple of places to start your research.
Use any of the 3 databases listed in the box titled "Basic Info on the EU" to answer these questions:
1. What is another name for the Treaty of the European Union?
2. What year was the Treaty of the European Union signed? What year did it go into effect?
3. What were the 12 founding nations in the EU (based on the Treaty of the European Union)?
