Territorial development of Czechoslovakia in 1918‒1924
The shape of the Czechoslovak borders and territories was legally anchored by a series of peace treaties – the Treaty of Versailles that emerged from the Paris Peace Conference in 1919–1920.The individual treaties, which concerned the demarcation of the Czechoslovak borders, were signed with Germany in Versailles, with Austria in Saint-Germain-en-Laye and with Hungary in Trianon. The basic requirements of Czechoslovakia regarding the recognition of its state borders had been proposed by Tomáš Garrigue Masaryk already during the First World War. The actual border adjustments proceeded until 1924.

Development of border provinces with predominance of German population in Czechoslovakia
On 21 October 1918, the independent state of German Austria, Deustch-Österreich was declared in Vienna. In addition to the Austrian lands, it was to include the border areas of Bohemia, Moravia and Silesia. After the establishment of independent Czechoslovakia on 28 October 1918, representatives of the Sudeten Germans declared four separatist provinces. The independent enclaves were to include the towns of Brno, Jihlava and Olomouc. The Czechoslovak government suppressed these separatist attempts with the use of the army.

Territorial development of Czechoslovakia following the Munich Agreement and the Vienna Award
The Munich Agreement of 29 September 1938 entailed significant territorial losses for Czechoslovakia and violation of its territorial integrity. From 1 to 10 October 1938, German troops annexed four territorial zones defined by the great powers in Bohemia and Moravia including Petržalka in Bratislava. The fifth zone was set out by an international committee of signatories to the Munich Agreement at a meeting in Berlin in October 1938.Poland and Hungary also enforced their claims on parts of Czechoslovakia. Territories seized from Czechoslovakia represented about 38 % of its original area and 36 % of the population of Bohemia and Moravia.

Czechoslovakia within the post-1945 borders. The Czech Republic within the post-1992 borders
In 1945, Czechoslovakia was restored within borders valid on 30 September 1938.After the Second World War, Subcarpathian Ruthenia became part of the Ukrainian Soviet Socialist Republic under a treaty between Czechoslovakia and the Soviet Union of 29 June 1945.In 1947, Czechoslovakia gained three villages from Hungary on the right bank of the Danube – Jarovce, Rusovce, Čunovo and part of the Rajka region (today part of Bratislava).In the period from 1947 until 1992, there were no significant changes of the state borders. The establishment of the Czech Republic and the Slovak Republic on 1 January 1993 brought about minor border adjustments, most recently in 1997. These involved parts of the village of Sidonie (the territory passed to the Czech Republic) and U Sabotov (to the Slovak Republic).
