In what year did Malta join the European Union?

Malta joined the European Union in 2004, becoming an EU member on 1 May of that year.

Its accession was part of the EU’s 2004 enlargement, the bloc’s largest expansion at the time. Malta joined alongside Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia and Slovenia. The enlargement expanded the EU from 15 to 25 member states.

Malta held a membership referendum on 8 March 2003. About 54% of voters supported joining, and the country subsequently signed the 2003 Treaty of Accession in Athens on 16 April. After the treaty was ratified, Malta formally entered the EU on 1 May 2004.

Joining the EU did not mean that Malta immediately adopted the euro. Malta continued using the Maltese lira until 2008, when it entered the euro area. This distinction explains why 2004 is the correct answer for EU membership, while 2008 is the relevant year for Malta’s currency change. Malta remains one of the EU’s smallest member states by both territory and population.
