In a letter addressed to Nikolić from Rome on 21 January 1956, Lukas granted his approval to him to continue to publish Croatian Review, the most important Croatian political émigré periodical. Filip Lukas was the president of the most prominent cultural and literary institution, Matica hrvatska, from 1928 to 1945, but afterward he had to flee to Italy. Matica hrvatska printed this periodical from 1928 to 1945, but the new editorial board appointed by communists ceased publication. Nikolić respected the president of Matica in exile, and therefore asked him to use the name of Zagreb's Croatian Review. Lukas permitted him to continue to publish it, but only under one condition: that it would return to the homeland when Croatia freed itself of communist rule, in order to maintain the continuity of activity of the journal at home and in exile.
