Catherine of Bosnia, Countess of Cilli

Catherine of Bosnia (Bosnian: Katarina Kotromanić, Slovene: Katarina Celjska - Kotromanićka)[1] (fl. 14th century) was a Bosnian noblewoman. She was Countess of Cilli by her marriage to Hermann I, Count of Cilli, and a member of the House of Kotromanić by birth.


It is known that Catherine was of Bosnian origin, but her parentage is disputed. Some [2] believe that Catherine was the daughter of Vladislav Kotromanić and his wife Jelena Šubić. Others [3] believe she was the second daughter of Stephen II, Ban of Bosnia, and his third wife Elizabeth of Kuyavia. If Catherine was a daughter of Stephen, she is the sister of Queen Elizabeth of Hungary; if she was a daughter of Vladislav, she was sister of King Tvrtko I of Bosnia.

Catherine's parentage is not clear because there is no evidence to link Catherine to either of the couples.[4]


Catherine was married in 1361 (or 1362) to Hermann I, Count of Cilli (Celje). The couple were married for twenty-three years and had at least two children:

  1. Hans of Cilli, died young
  2. Hermann II, Count of Cilli, married Countess Anna of Schaunberg and became father of Holy Roman Empress Barbara.
