In 1952, she enrolled at the University of Ljubljana, where she studied history. She obtained her PhD in 1970 under the supervision of Vasilij Melik. From 1959 onward, she worked at the Institute of Contemporary History in Ljubljana. Between 1979 and 1983, she was head of the institute.[2]
Marxist pressures against her work
Because her research topic was the history of an ethnic minority and not the history of the working class, her work was subjected to Marxist criticisms by Dušan Kermavner during Slovenia's socialist period.[2]
Work
Her works on Slovene and Croat anti-Fascist resistance against Italianization are considered pioneering. She was one of the first historians to engage in thorough research of the militant anti-Fascist organization TIGR.
