Ivan Katardžiev

In 1948, he was among the 13 students from Pirin Macedonia in Skopje, out of a total of about 140 there, who signed a declaration against the new decisions of the Central Committee of the Bulgarian Communist Party.

With them, the "cultural autonomy" practically stopped and a return to the party's position from before 1934, of denying the Macedonian identity, began.

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.

[2] In 1961 he promoted the thesis the first official name of the IMRO was Bulgarian Macedonian-Adrianopolitan Revolutionary Committees.

[6][7][8] In October 2014 the Lustration Commission of Macedonia named Katardžiev as an informer of the Communist Yugoslavia's UDBA during the 1950s.
