The Hungarian Soviet Republic was the political regime in Hungary from March 21, 1919 until the beginning of August of the same year, and it is the second Communist (or soviet) government in world history, after the one in Russia (1917).
The immediate cause of the formation of the Hungarian Soviet Republic was the failure of Count Mihály Károlyi's government of the re-born state of Hungary to reorganize the country's social and economic life on the shambles left over after the lost war and the dissolution of the Austro-Hungarian Empire.
A spurious Slovak Soviet Republic was proclaimed on June 16, in the southern and eastern Slovakia.
Therefore, Hungarian politics and culture of the interwar period were saturated with irredentism and revisionism (the restoration of 19th century "greater Hungary" by whatever means necessary).
Hungarian sovereign debt was upgraded in 2000 to the second-highest rating among all the Central European transition economies.
Several large Hungarian minorities exist across the border in neighbouring countries, notably in Ukraine (in Transcarpathia), Slovakia, Romania (in Transylvania), Serbia (in Vojvodina) and a smaller ones in Austria (in Burgenland), Croatia and Slovenia.
