The size of a golf course, the Vatican City is the smallest country in the world. It's basically a walled enclave inside of Rome, Italy. It's so small that the entire country does not have a single street address. The Vatican City may be small, but it is very powerful. It is the sovereign territory of the Holy See, or the seat of the Catholic Church (basically its central government), which has over 1 billion people (about 1 in 6 people on the planet) as constituents. The Vatican City was created in 1929 by the Lateran Treaty (which was signed by one of history's most repressive dictators, Benito Mussolini) and is ruled by the Pope, basically a nonhereditary, elected monarch who rules with absolute authority (he's the legislative, executive and judiciary all rolled into one) indeed, the Pope is the only absolute monarch in Europe.
