The Aster Revolution or Chrysanthemum Revolution (Hungarian: Őszirózsás forradalom) was a revolution in Hungary led by Count Mihály Károlyi in the aftermath of World War I which resulted in the foundation of the short-lived First Hungarian People's Republic.The revolution was brought about by widespread protests as World War I wore on, from which Mihály Károlyi emerged as the leader of the newly proclaimed First Hungarian People's Republic that reigned between 16 November 1918 and 21 March 1919. During this period of time, he served as Prime Minister between 1 and 16 November 1918 and as President between 16 November 1918 and 21 March 1919. The supporters of Károlyi that consisted of citizens and demobilized soldiers adopted aster as the symbol of the revolution, viz., they stuck asters (őszirózsa: literally autumn = ősz and rose = rózsa) in their hats and caps in the streets of Budapest to symbolize their support for the social democratic Hungarian National Council (HNC) and Count Károlyi. After the victory of the revolution, Hungary declared its independence and, as a result, Austria-Hungary dissolved.
