Vatican City
The name was first used in the Lateran Treaty, signed on 11 February 1929, which established the modern city-state. The name is taken from Vatican Hill, the geographic location of the state. "Vatican" is derived from the name of an Etruscan settlement, "Vatica" or "Vaticum" meaning garden, located in the general area the Romans called "vaticanus ager", "Vatican territory".
Ages of consent in Europe
When the Vatican City was first formed, it adopted the then-Italian age of consent of 12 as per the Lateran Treaty of 1929. Until July 2013 it had the lowest age of consent in Europe, but after that month, when the Pope made his decree, it became the highest.
