Sedes Sacrorum (Latin Sedes for seat/see, Sacrorum for holy) otherwise known as Santa Sede and the “SS" also known in English as "Holy See" refers to the legal apparatus as a whole by which the Roman Catholic Pope and its Curia of Bishops claim historical recognition as a sovereign entity with superior legal rights. The Catholic Church uses two legal personalities with which to conduct its international affairs: the first is as an International State known as the Vatican City State, to which the Pope is the Head of Government. The second is as the supreme legal personality above all other legal personalities by which all property and "creatures" are subjects. The legal enforcability of its first personality as an International State is constrained by international law. The sovereign status of the Vatican City remains dependent upon the continued recognition of an agreement known as the "Lateran Treaty" signed between Catholic Facist Dictator and mass murderer Benito Mussolini in 1929 and his political supporter Pope Pius XI. This recognition remains in defiance and contempt to existing international laws prohibiting recognition of rogue states and laws created by mass murdering dictators. The legal enforcability of the second personality of the Catholic Church as the Holy See is dependent upon the continued adherence to legal statutes, definitions, conventions and covenants as have been accumulated since the Middle Ages concerning the primacy of the Pope over all property and creatures. Theses statutes, conventions and covenants remain the fabric and foundation of the modern legal system of most states in the world. To extend its legal strength using its second personality, the Catholic Church considers the region controlled by every bishop a See.
