Diplomat Ivan Rebernik passed away on April 16, 2026, at the age of 86. Introduction Ivan Rebernik was a Slovenian diplomat and librarian who spent much of his life working in Catholic and international institutions in Rome. He served as Ambassador of Slovenia to the Holy See and combined this diplomatic role with a long career in the library world. In doing so, he occupied a unique position at the intersection of culture, religion, and international relations. Political Career Rebernik built his public career in Rome, where he lived from 1960 onwards. His work took place in an environment where religious heritage, scholarship, and diplomacy directly intersected. From 1964 to 1988, he worked at the library of the Pontifical Gregorian University. From 1980 to 2004, he also worked at the Vatican Library. In these positions, he dealt with important Catholic collections, papal archives, and religious manuscripts. This years-long experience gave him exceptional expertise in ecclesiastical heritage and Vatican institutions. This later made him relevant for diplomatic representation on behalf of Slovenia. As Ambassador of Slovenia to the Holy See, he represented his country in relations with the Vatican. For independent Slovenia, this position held clear symbolic and practical significance, as the country continued to establish its place in the international community after 1991. Rebernik was thus regarded as a representative of a generation of Slovenian intellectuals who built their careers within international institutions. His work demonstrated how cultural knowledge and diplomacy can reinforce each other, particularly for a smaller European nation. From 2012 to 2016, he served as Chancellor of the Order of the Holy Sepulchre. In this role, he was associated with an ancient Catholic knightly order dedicated to the preservation of Christian heritage, particularly in relation to the Holy Land.
