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".
Languages of Vatican City
What became Vatican City was from 1870 to 1929 part of the Kingdom of Italy, whose official language also was Italian, and before 1870 it was part of the Papal States, in which standard Italian (based on Tuscan) and various Italian dialects, such as Emiliano-Romagnolo, were spoken, but which for the first centuries of its existence used Latin for all official purposes. Earlier still, it was part of the Roman Empire. In the earliest historical records the term "Vatican" was used to refer to a marshy area, larger than the Vatican City State, on the right bank of the Tiber River, between the Milvio Bridge and the present Sixtus Bridge. During the monarchy and the republican age, the area was known as "Ager Vaticanus". From the 2nd century A.D., the toponym "Vaticanum" was applied to an area corresponding roughly to the present Vatican City State.
