Hungarian Democratic Republic
On October 31, 1918, the Hungarian Democratic Republic was created by revolution that started in Budapest after the dissolution and break-up of Austria-Hungary at the end of World War I. The official proclamation of the republic was on November 16, 1918, and Mihály Károlyi was named as the republic's Prime Minister. This event also marked the independence of Hungary which had been ruled by the Habsburg Monarchy for several centuries.
