Italy is a republic in Europe founded following the end of World War II. Following its unification and establishment of a monarchy in the 19th century, Italy became one of Europe's great powers, with a large African colonial empire. Despite fighting for the victorious side in World War I, the resulting economic and social turmoil lead to a fascist dictatorship under Benito Mussolini. Mussolini's attempt to form a "New Roman Empire" led to Italy joining the Axis Powers in World War II. Italy was defeated in the war, with both its dictatorship and monarchy being overthrown and replaced with a democracy. Since then, Italy has enjoyed economic success and is now considered a European regional power.
