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".
Old Catholic Church
After the First Vatican Council (1869–1870), several groups of Catholics in Austria-Hungary, Imperial Germany, and Switzerland rejected the Roman Catholic dogma of papal infallibility in matters of faith and morals and left to form their own churches. These were supported by the Old Catholic Archbishop of Utrecht, who ordained priests and bishops for them. Later the Dutch were united more formally with many of these groups under the name "Utrecht Union of Churches".
