description: "Mikhailo or Mikhail Olelkovich was a noble from the Olelkovich family of the Grand Duchy of Lithuania who served as the appanage prince of Kopyl and Slutsk. He was the younger brother of Simeon Olelkovich, the prince of Kiev, and a cousin of Ivan III, the grand prince of Moscow. Mikhailo was allegedly involved both in bringing the Judaizers to Novgorod and the failed defection of the city's nobles to the Grand Duchy of Lithuania in 1471. He also organized a coup against Casimir IV Jagiellon, the king of Poland and grand duke of Lithuania, but was discovered and executed in 1481. Mikhailo's son Simeon continued the family line."
