Ivan Katardžiev

Ivan Katardžiev (; ; January 6, 1926 – December 1, 2018) was a Macedonian historian. He was regarded as the country's most important expert on the Internal Macedonian Revolutionary Organization (IMRO) and the Macedonian history under Yugoslavia as well as the early years of independence. He was also director of the Macedonian Institute for National History. Thus, in practice, Katardžiev remained living in Yugoslavia.

In the 1950s he was head of the University Library of Skopje, the Diaspora Office and served as secretary of the Institute for National History of Macedonia.

In recent years Katardžiev criticized the then Macedonian ruling party, the VMRO – DPMNE, for rehabilitating several IMRO revolutionaries, who had previously been blacklisted during Yugoslav rule for being Bulgarophiles.

In October 2014 the Lustration Commission of Macedonia named Katardžiev as an informer of the Communist Yugoslavia's UDBA during the 1950s. They accused him of spying on history students who originated from Bulgarian Macedonia. Katardžiev at the time was head of the University Library in Skopje as well as the Diaspora Office.
