From 1945 to 1991 Matica was active in SR Croatia that was member of the Yugoslav Federation since the end of World War II. It was difficult for Matica to work due to the negative attitude of the central government in Belgrade to the institution with a national character because Yugoslavia was distinctly multi-ethnic state and it was considered that any over-emphasis of nationalism could undermine the unity of the people of Yugoslavia. Matica's buildings were nationalized and also many other publishers appeared. But regardless these difficulties Matica continued to actively publishing various books, anthologies about Rijeka, Zadar and the Croatian National Revival, anthology of legal texts, philosophical texts, art monographs etc.
