The 1587 Siege of Kraków took place between 14 October and 29 November 1587, after the contested 1587 Polish–Lithuanian royal election, which resulted in a double selection of opposing candidates - Zygmunt Waza was elected by the nobility on the 19th of August, while another faction of the gentry chose Maximilian III, Archduke of Austria, on the 22nd of August.
