Sigismund returned to Hungary in 1401 and, facing a number of revolts, gradually resumed control and re-asserted himself as the King of Hungary. This was achieved by allying himself with the political party of Stibor of Stiboricz, Nicholas II Garay, and Hermann II of Celje, in return for their military support, which enabled him to fight off domestic rivals. Sigismund campaigned against the Croatian nobility which culminated in 1408 with the Battle of Dobor in Usora.[5] In the aftermath of this battle, and events unfolding in what is known as the Bloody Sabor of Križevci, 171 members of Bosnian nobility were also massacred.
