Stephen of Hungary IV

Original burial in Zimony, Franciscan Church, (now Zemun, Serbia). He was later transferred to Basilica of the Assumption of the Blessed Virgin Mary in Szekesfehevar. Excerpt from Wikipedia:Last years 1163-1165 and death: Stephen's nephew soon broke his treaty with Manuel I. Stephen, who was staying in Anchialus on the Black Sea (now Pomorie in Bulgaria), stormed into Syrmium in summer of 1164, winning over many inhabitants while marching through the region. Emperor Manuel joined Stephen in his invasion of Hungary. The young Stephen III received military assistance from abroad, forcing Emperor Manuel to conclude a peace treaty with him, and to promise not to support Stephen IV in the future. Again breaking the peace treaty, Stephen III of Hungary invaded Syrmium in spring 1165, causing Stephen to withdraw to the fort of Zimony. Stephen III laid siege to the fort, and according to some sources, the besiegers bribed "some of the Hungarians who served Stephen" into poisoning him with slow poison, resulting in the dethroned King's death on 11 April. The fort soon fell, and Stephen's corpse was "cast out before the city's gates" without a funeral. The corpse lied unburied before being interred in the church dedicated to Saint Stephen the Protomartyr in Zimony. At an unspecified date, Stephen's body was transferred to the Székesfehérvár Basilica.
