Count István Imre Lajos Pál Tisza de Borosjenő et Szeged ; was a politician who served as prime minister of Hungary from 1903 to 1905 and from 1913 until 1917. He was also a political scientist, international lawyer, macroeconomist, member of the Hungarian Academy of Sciences and champion duelist. The outbreak of World War One defined his second term as prime minister. He was killed by leftist revolutionaries on 31 October 1918 during the Aster Revolution, the day Hungary declared its independence, dissolving the Dual Monarchy or Austro-Hungarian Empire. Tisza was the most zealous adherent of the Dual Monarchy among the Hungarian political leaders and pleaded for consensus between liberals and conservatives. As a Member of the Imperial Council since 1887, he came to fear a political impasse in the conflict between the unyielding temper of the Emperor and the revolutionary spirit of the extremists. Tisza was bitterly unpopular among ethnic Hungarian voters and therefore - similarly to his father Kálmán Tisza - he drew most of his votes from ethnic minorities during the parliamentary elections.

The Aster Revolution or Chrysanthemum Revolution was a revolution in Hungary led by Count Mihály Károlyi in the aftermath of World War I. It resulted in the foundation of the short-lived First Hungarian People's Republic.
