Komárom

Komárom (Hungarian: [ˈkomaːrom]; German: Komorn or Comorra; Latin: Brigetio, later Comaromium; Slovak: Komárno) is a city in Hungary on the south bank of the Danube in Komárom-Esztergom County. Komárom fortress played an important role in the Hungarian Revolution of 1848 and many contemporary English sources refer to it as the Fortress of Comorn.

Komárom on the south bank was formerly known as a separate village called Újszőny (or Szony). Komarom on the north bank and Újszőny were connected in 1892 with an iron bridge across the Danube. The two towns were united under the name of city of Komárom in 1896.

On 4 June 1920, the Treaty of Trianon that broke up the Austria-Hungary Empire split the city in two, because the southern border of Czechoslovakia was determined by the river Danube. This division separated the historical Komárom county of the Kingdom of Hungary and the city of Komárom.

The bigger, northern part of the city was attached to Czechoslovakia and renamed Komárno. Its population resulted in a sizable ethnic Hungarian minority in present-day Slovakia. The southern part of the city, lying south of the Danube, remained in Hungary.

On 2 November 1938 by the First Vienna Award, the northern part of the city was returned to Hungary, and divided Komárom was reunified. At the end of World War II, the city was again divided between Czechoslovakia and Hungary.

Following the breakup of Czechoslovakia, two nations were established: the Czech Republic to the north and Slovakia to the south. Komárno is in today's Slovakia on the northern bank of the Danube.
