It may be difficult to imagine, but there is a country in the world smaller than New York City’s Central Park and one with a population smaller than a typical high-school class. Based on landmass, Vatican City is the smallest country in the world, measuring just 0.2 square miles, almost 120 times smaller than the island of Manhattan.
Situated on the western bank of the Tiber River, Vatican City’s 2-mile border is landlocked by Italy. The official seat of the pope of the Catholic Church since 1377, Vatican City was not declared an independent state until the Lateran Treaty of 1929.
After years of power struggles between popes and the political leaders of Italy over who could claim supreme authority in the region, Benito Mussolini and Pope Pius XI agreed to the Lateran Pacts on February 11, 1929, which created the independent state of Vatican City for the Catholic Church in exchange for the pope’s recognition of the Kingdom of Italy. Today, nearly 75 percent of the Vatican’s citizens are members of the clergy.
