Italy is a boot-shaped peninsula in Southern Europe surrounded by the Tyrrhenian Sea and Adriatic Sea. It has a unitary parliamentary republic government and has been led by Prime Minister Matteo Renzi since 2014. Italy has a long history dating back to ancient civilizations and was not unified until the 19th century. It was then led by Mussolini as a dictatorship until his death in 1945. Since World War 2, Italy has been a member of NATO and the EU and uses the euro as its currency. Standard Italian is the official language though regional dialects still exist.
