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".
Vatican and Eastern Europe (1846–1958)
The relations with Russia changed drastically for a second reason. The Baltic states and Poland gained their independence from Russia after World War I, thus enabling a relatively free church life in those former Russian countries. Estonia was the first country to look for Vatican ties. On 11 April 1919, Secretary of State Pietro Gasparri informed the Estonian authorities that the Vatican would agree to have diplomatic relations. A concordat was agreed upon in principle a year later, in June 1920. Because of the small Catholic population in predominantly Protestant Estonia, the handful of Catholic priests there continued to be administered from Latvia until 1924. Development of an independent Catholic hierarchy for Estonia began late in that year with the formation of the Apostolic Administration of Estonia in November.
