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".
Military in Vatican City
The Pontifical Swiss Guard () was formed in 1506 by Pope Julius II. The unit was formed as the personal bodyguard of the Pope. At various points in its history the Swiss Guard has seen active service, but following the 1870 abolition of the Papal States it returned to its chief role as a bodyguard, with a limited ceremonial role, and survived into the period of the Vatican City State, as a "de facto" Vatican military unit from 1929.
