Cisleithania, officially The Kingdoms and Lands Represented in the Imperial Council (German: Die im Reichsrat vertretenen Königreiche und Länder), was the northern and western part of Austria-Hungary, the Dual Monarchy created in the Compromise of 1867—as distinguished from Transleithania (i.e., the Hungarian Lands of the Crown of Saint Stephen east of ["beyond"] the Leitha River). This name for the region was a common, but unofficial one. The Cisleithanian capital was Vienna, the residence of the Austrian emperor. The territory had a population of 28,571,900 in 1910. It reached from Vorarlberg in the west to the Kingdom of Galicia and Lodomeria and the Duchy of Bukovina (today part of Ukraine and Romania) in the east, as well as from the Kingdom of Bohemia in the north to the Kingdom of Dalmatia (today part of Croatia) in the south. It comprised the current States of Austria (except for Burgenland), as well as most of the territories of the Czech Republic and Slovenia (except for Prekmurje), southern Poland and parts of Italy (Trieste, Gorizia, Tarvisio, Trentino, and South Tyrol), Croatia (Istria, Dalmatia), Montenegro (Kotor Bay), Romania (Southern Bukovina), and Ukraine (Northern Bukovina and Galicia).
