Records of prime ministers of Hungary

The prime minister with the longest single term was Count Kálmán Tisza, lasting 14 years and 144 days from 20 October 1875 until 13 March 1890.

The shortest ever period was only 17 hours, a record held by Count János Hadik, from 30 October to 31 October 1918, who was asked to form a government by King Charles IV but the Aster Revolution broke out led by leftist liberal Count Mihály Károlyi, who founded the Hungarian Democratic Republic.

By the end of the day, King Charles IV had accepted the coup and appointed Károlyi as Hungary's new prime minister.

The oldest prime minister to be appointed was Baron Géza Fejérváry on 18 June 1905 at the age of 72 years, 3 months and 3 days.

The youngest prime minister to leave office was András Hegedüs, who left the country during the Hungarian Revolution of 1956, aged 34.

Dezső Pattantyús-Ábrahám, the prime minister of the third Counter-Revolutionary Government during the Hungarian Soviet Republic died on 25 July 1973, at the age of 98 years and 15 days.
