The round table on the House of Celje/de Cilie took place as a constituent part of the 21st meeting of the Slovene historians in Celje on October 1, 1982. One of the reasons for organizing the round table was the publication of the book by Nada Klaić on the House of Celje in Croatia ("The last princes of Celje in the lands of the Holy Crown"). The participants of the round table discussed the significance of the Celje and other feudal families in the Slovene history and the relation of the Slovene historiography to the House of Celje. The discussion pointed out a series of only partly solved or completely unsolved questions which could be answered only when the stili unused archive sources would be studied.
