Rebellion of wójt Albert

The Rebellion of mayor Albert (Polish: bunt wójta Alberta) was an uprising by the burghers of the Polish city of Kraków against the duke Władysław I the Elbow-high in the years 1311–12. The mutiny was led by Albert, the vogt (Latin: advocatus, Polish: wójt) who was effectively a mayor of the town under Magdeburg Law. It ended with the duke (later king) Władysław's victory.

After Kraków had been devastated during the 1241 Mongol invasion of Poland, it was re-established according to Magdeburg Law by Prince Bolesław V the Chaste. In 1291 the Duchy of Kraków fell to the Přemyslid king Wenceslaus II of Bohemia who in 1300 also became King of Poland. Upon the extinction of the Přemyslids in 1306, the Piast duke Władysław I the Elbow-high assumed the rule at Kraków, while in 1310 the Bohemian Kingdom passed to the House of Luxembourg. The new king, John of Bohemia, continued to claim the Polish royal title and moreover sought to vassalize the Piast dukes of the adjacent Silesian region.

In 1311 wójt Albert (?-1317), mayor of Kraków (1290-1312), instigated a mutiny against Prince Władysław, with the goal of turning the city – then the capital of the Polish Seniorate Province – over to the Bohemian House of Luxembourg. Albert, himself of German or Czech origin, had the support of some of the city's German burghers. He also had the support of Bishop Jan Muskata, himself of German-Silesian origin, and the Silesian duke Bolko I of Opole, as well as of many Kraków citizens. After Władysław laid siege to the city, the revolt ended in failure. Similar rebellions took place in several other cities, particularly Sandomierz and Wieliczka; these were also crushed by Władysław.
