 Jadwiga and her Polish advisers invited the Grand Master, Konrad von Jungingen, to Poland to open new negotiations in June 1396.Conflicts with Vladislaus of Opole and Siemowit of Masovia, who had not given up their claims to parts of Ruthenia and Cuyavia, also intensified.To demonstrate that the territories were under Jadwiga's direct control, Władysław-Jogaila granted the Duchy of Belz (in Ruthenia) and Cuyavia to her in early 1397.
