Sigismund granted Osor and Cres in Dalmatia to Nicholas and his brother in May. The two estates had been possessed by John Szerecsen and his sons, who failed to pay the taxes due to the bans. Sigismund held a Diet (or legislative assembly) at Temesvár (now Timișoara in Romania) to adopt measures to secure the defense of the southern frontier of the kingdom. At the Diet, the king granted "the banship of Dalmatia, Croatia and Slavonia together with its appurtenances and income" to Nicholas and John Garai till the end of their lives on 2 November.
