Austria-Hungary

Territorial legacy

Immediately after World War I

The following states were formed, re-established or expanded at the dissolution of the former Austro–Hungarian monarchy:

German Austria (which became the Republic of Austria)

First Hungarian Republic which became the Hungarian Soviet Republic, subsequently briefly restored and replaced by the Hungarian Republic, ultimately transformed into the Kingdom of Hungary

First Czechoslovak Republic, later "Czechoslovakia"

Second Polish Republic, contested by the short-lived proto-states of Tarnobrzeg Republic and Polish Soviet Socialist Republic

State of Slovenes, Croats and Serbs and the Kingdom of Serbia, both later absorbed into the Kingdom of Serbs, Croats and Slovenes

Greater Romania

Kingdom of Italy

Republic of China (former Austro-Hungarian concession of Tianjin)

the short-lived Ruthenian (Ukrainian and Rusyn) proto-states of West Ukrainian People's Republic (later absorbed into Ukrainian People's Republic), Hutsul Republic, Lemko Republic, Komancza Republic and the Galician Soviet Socialist Republic; all were ultimately absorbed mostly into Poland, but also into Hungary, Czechoslovakia, Romania and Yugoslavia.

The Principality of Liechtenstein, which had formerly looked to Vienna for protection and whose ruling house held sizable real estate in Cisleithania, formed a customs and defense union with Switzerland, and adopted the Swiss currency instead of the Austrian. In April 1919, Vorarlberg—the westernmost province of Austria—voted by a large majority to join Switzerland; however, both the Swiss and the Allies disregarded this result.

Peace of Prague (1866)

The Peace of Prague (German: Prager Frieden) was a peace treaty signed by the Kingdom of Prussia and the Austrian Empire at Prague on 23 August 1866. In combination with the treaties of Prussia and several south - and central German states it effectively ended the Austro-Prussian War.

The treaty was lenient toward the Austrian Empire because Otto von Bismarck had persuaded Wilhelm I that maintaining Austria's place in Europe would be better than harsh terms for the future for Prussia.
