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".
History of the Kingdom of Italy (1861–1946)
In 1929 Mussolini signed the Lateran Pacts with the Roman Catholic Church (with which Italy had been in conflict since the annexation of Rome in 1870), leading to the formation of the tiny independent state of Vatican City. He was initially on friendly terms with France and Britain, but the situation changed in 1935–36, when Italy invaded the Ethiopian Empire despite their opposition (Second Italo-Abyssinian War); because of this and of the ideological affinities with the Nazi party led by Hitler. It was a main part of the Axis Powers in World War II with allies being Imperial Japan and Nazi Germany as the "Rome-Berlin-Tokyo Axis".
