The Hungarian war of succession of 1440–1442 was a war of succession in the Kingdom of Hungary between the supporters of Elizabeth of Luxembourg and her infant son, king Ladislaus V the Posthumous, and the supporters of King Vladislaus I the Jagiellonian (Władysław III in Poland). The conflict was caused on 27 October 1439 by the death of king Albert II of Habsburg, husband of the pregnant Elizabeth, who gave birth to Ladislaus on 22 February 1440 after Albert had already died (hence Ladislaus' nickname "the Posthumous").
