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".
Second Vatican Council
Pope Paul VI opened the last period of the Council on 14 September 1965 with the establishment of the Synod of Bishops. This more permanent structure was intended to preserve close cooperation of the bishops with the Pope after the council.
