History
As a result of the Treaty of Trianon - the peace treaty by Hungary that ended its role in First World War - a bridgehead was created for Czechoslovakia on the right bank of river Danube at Bratislava, mainly for defensive purposes. At this time Petržalka was transferred to the newly founded country.

In October 1938, as part of the Munich Agreement, Petržalka and Devín were transferred to Nazi Germany for strategic purposes.

At the end of World War II, ceasefire agreements mainly restored the pre-war boundaries, except Carpathian Ruthenia, which became part of Soviet Ukraine as per the Moscow Agreement. A camp for Hungarians and Germans interned for war crimes was located in Petržalka.

It was an idea of the Czechoslovakia delegation at the Paris Peace Conference that they would need an extended defensive territory at the Bratislava bridgehead. They sought Dunacsún (Čunovo), Horvátjárfalu (Jarovce), Oroszvár (Rusovce), Rajka and Bezenye. The first three were transferred, creating a territory of 62 km2.

During the 1970s, a microdistrict was built at Petržalka, with a population of 100,000 inhabitants. Today; its four villages are a part of the Bratislava V district.

Between 1977 and 1992, the Gabčíkovo–Nagymaros Dams was built there. The bridgehead makes the extraction of water to Slovakia possible.
