Vatican City is a city-state within Italy and the seat of Roman Catholicism
There's really just not enough data on Vatican City to relate it to other countries, so we're just having some fun here.
With its 61,680,122 people, Italy is the 23rd largest country in the world by population. It is the 72nd largest country in the world by area with 301,340 square kilometers.
Italy became a nation-state in 1861 when the regional states of the peninsula, along with Sardinia and Sicily, were united under King Victor EMMANUEL II. An era of parliamentary government came to a close in the early 1920s when Benito MUSSOLINI established a Fascist dictatorship. His alliance with Nazi Germany led to Italy's defeat in World War II. A democratic republic replaced the monarchy in 1946 and economic revival followed. Italy is a charter member of NATO and the European Economic Community (EEC). It has been at the forefront of European economic and political unification, joining the Economic and Monetary Union in 1999. Persistent problems include sluggish economic growth, high youth and female unemployment, organized crime, corruption, and economic disparities between southern Italy and the more prosperous north.
