The manuscript of the article deals with Brandt's reminiscences on his role in composing and signing of Declaration on the Name and Status of Croatian Language in March 1967. He described the anxiety among the leaders of Matica Hrvatska when the text of the Declaration had been published. Besides his own role in this matter, he also stressed that Matica Hrvatska liberated itself from the secret policy in the time of the so-called liberalization of Titoism in the 1960s. From Brandt's point of view, the central personality of Declaration was Professor Ljudevit Jonke, who worked in the Croatian Language Department at the Faculty of Humanities in Zagreb. In the end, Brandt recounted the destiny of Declaration’s creators, who were expelled from Croatian scholarly and cultural life just as he was him after the suppression of the Croatian Spring in 1971.
