In 1506 the duchy was incorporated into the Bohemian (Czech) Kingdom, although Polish King Sigismund I the Old still claimed the duchy before renouncing claims in 1508,[7] while his wife, Polish Queen Bona Sforza still made attempts to reintegrate the city and the duchy with the Kingdom of Poland in 1522, 1526 and 1547.[2] Nevertheless, it remained under the Czech Crown during the rule of the Jagiellonian dynasty until 1526, when it was inherited by the Austrian House of Habsburg and was incorporated into the Habsburg monarchy.
