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 Palatine Guard () was formed in 1850 by Pope Pius IX, through amalgamation of two older units of the Papal Army. The corps was formed as an infantry unit. It saw active service during the token resistance to the occupation of Rome by Italian government troops in 1870, and it survived into the period of the Vatican City State, as a "de facto" Vatican military unit (including a ceremonial military band) from 1929 to 1970.
