Mantigirdaitis is mentioned as the first Grand Hetman of Lithuania. The Bychowiec Chronicle describes how Grand Duke Alexander visited the ailing Mantigirdaitis in Trakai and asked for his recommendations for a successor. Mantigirdaitis recommended Konstanty Ostrogski.[4] Mantigirdaitis is also mentioned as Hetman in a surviving copy of a donation document by Grand Duke Alexander that Vytas Jankauskas dated March 1494. If the date is correct, this would indicate that the Hetman position developed during the First Muscovite–Lithuanian War (1492–94).[4]
There is no information available on his father, thus historians assume he died in his youth.[1] Mantigirdaitis was married twice. His first wife was Anna, daughter of Jonas Vėževičius, regent of Smolensk.[1] They had a son and a daughter. Their son Jonas died in the Battle of Vedrosha ending the family line.[5] Their daughter Sophia married Stanisław Kiszka, who inherited the family's substantial wealth.[6] Mantigirdaitis' second wife was Anna, daughter of Alexander Alšėniškis[1] or of Fyodor Koributovich [ru], son of Kaributas;[4] they had no children. In 1482, Anna funded the Chapel of Holy Trinity in Vilnius Cathedral.[1] It is likely that Mantigirdaitis funded the Catholic church in Iwye, his most important estate.[5]
