1) Is Vatican City not a member of the EU? 2) Did Latvia join the EU in 2004? 3) Are countries that are undemocratic

1) Vatican City is indeed not a member of the European Union (EU). This is because the EU is a political and economic union of European countries, while Vatican City is an independent city-state and the spiritual headquarters of the Roman Catholic Church. It is recognized as a separate sovereign entity and maintains diplomatic relations with the EU, but it is not a member.

2) Yes, Latvia joined the EU in 2004. Along with nine other countries, including Estonia and Lithuania, Latvia became a member of the EU on May 1, 2004. This expansion brought the EU to a total of 25 member states at that time.

3) The ability to join the EU is not solely based on whether a country is democratic or undemocratic. However, one of the fundamental values of the EU is the promotion of democracy, human rights, and the rule of law. As part of the accession process, countries seeking EU membership are required to meet certain democratic standards and fulfill various criteria set by the EU. While undemocratic countries may face significant challenges in meeting these criteria, the EU does not explicitly exclude countries solely on the basis of being undemocratic.

4) Correct, not all EU countries use the euro as their currency. While the euro is the official currency of 19 out of the 27 EU member states, several countries have chosen to maintain their own national currencies. For example, countries like Denmark, Sweden, and the United Kingdom have opted to retain their respective currencies (Danish krone, Swedish krona, and British pound) instead of adopting the euro.

5) EMU stands for Economic and Monetary Union. It refers to the group of EU member states that have adopted the euro as their common currency and have established a coordinated economic policy framework. The EMU aims to ensure stability, coordination, and convergence in the monetary policies of participating countries to promote economic growth and stability within the Eurozone.

6) Yes, there were two major European wars in the twentieth century. The first major war was World War I, which took place from 1914 to 1918. It involved many European countries and resulted in significant political, social, and economic upheaval. The second major war was World War II, which started in 1939 and lasted until 1945. It was a global conflict that involved numerous countries, including European nations, and resulted in immense destruction and loss of life.

7) Yes, Britain left the EU, a process commonly known as Brexit. On January 31, 2020, the United Kingdom officially ceased to be a member of the EU, following a referendum held in 2016 where a majority of British voters expressed their desire to leave the EU. This decision had significant political, economic, and social implications for both the UK and the EU, and negotiations on various aspects of the UK"s future relationship with the EU are ongoing.
