Corpus separatum (Fiume)

Corpus separatum, a Latin term meaning "separated body", refers to the status of the City of Fiume (modern Rijeka, Croatia) while given a special legal and political status different from its environment under the rule of the Kingdom of Hungary. Formally known as City of Fiume and its District (Hungarian: Fiume város és kerülete[9]), it was instituted by Empress Maria Theresa in 1779, determining the semi-autonomous status of Fiume within the Habsburg Monarchy until the fall of the Austro-Hungarian Empire in 1918.
