Upon the death of the Hussite king, the Bohemian estates elected a Polish prince Ladislaus Jagiellon as king, who negotiated the Peace of Olomouc in 1479. In 1490 he also became king of Hungary, and the Polish Jagellonian line ruled both Bohemia and Hungary. The Jagellonians governed Bohemia as absentee monarchs; their influence in the kingdom was minimal, and effective government fell to the regional nobility. Czech Catholics accepted the Compact of Basel in 1485 and were reconciled with the Utraquists. The Bohemian estrangement from the Empire continued after Vladislav had succeeded Matthias Corvinus of Hungary in 1490 and both the Bohemian and the Hungarian kingdom were held in personal union. Not considered an Imperial State, the Lands of the Bohemian Crown were not part of the Imperial Circles established by the 1500 Imperial Reform.
