Хто одружився на Ulrich II, Count of Celje?

Ulrich II, or Ulrich of Celje (Slovene: Ulrik Celjski / Urh Celjski; Hungarian: Cillei Ulrik; German: Ulrich II von Cilli; 16 February 1406 – 9 November 1456), was the last Princely Count of Celje. At the time of his death, he was captain general and de facto regent of Hungary, ban (governor) of Slavonia, Croatia and Dalmatia and feudal lord of vast areas in present-day Slovenia, Croatia, Bosnia, Austria, and Slovakia. He was also a claimant to the Bosnian throne. He was killed by agents of the Hunyadi clan under unknown circumstances, which plunged Hungary into civil unrest that was resolved a year later by the sudden death of king Ladislas the Posthumous and the election of Matthias Corvinus, the son of John Hunyadi and Ulrich's son-in-law, as king. Ulrich's possessions in the Holy Roman Empire were inherited by Emperor Frederick III, while his possessions in Hungary were reverted to the crown.

Katarina Branković (Serbian Cyrillic: Катарина Бранковић, Greek: Καταρίνα Μπράνκοβιτς; 1418–1492), also known as Kantakuzina (Кантакузина, Kantakouzena) was the Countess of Celje, through the marriage with Count of Celje Ulrich II. A Serbian princess, she was the daughter of Despot Đurađ Branković and Byzantine princess Irene Kantakouzene. She is remembered for writing the Varaždin Apostol (1454), and her endowment of the Rmanj Monastery.
