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".
Ecumenism
The Old Catholic Church split from the Catholic Church in the 1870s because of the promulgation of the dogma of Papal Infallibility as promoted by the First Vatican Council of 1869–1870. The term "Old Catholic" was first used in 1853 to describe the members of the See of Utrecht who were not under Papal authority. The Old Catholic movement grew in America but has not maintained ties with Utrecht, although talks are under way between some independent Old Catholic bishops and Utrecht.
