The Pavao Tijan Collection is deposited in the Archives of the Croatian Academy of Science and Arts in Zagreb. It demonstrates the cultural-oppositional activities of the Croatian émigré Pavao Tijan, who lived in Madrid after the Second World War. There, Tijan organized anti-communist activities against the Yugoslav regime and also against global communism during the time of the Cold War. This collection is very important to the little known Croatian cultural history of the émigré colony of Spain.

The newspaper "Zemedelsko zname" (The Agrarian Banner) was the organ of the largest opposition party after the 9 September coup d'état - the "Bulgarian Agrarian People's Union - Nikola Petkov", the successor of the prewar peasant party which had roots in the early 20th century and ruled Bulgaria from 1919 to a coup in 1923. The newspaper, following the party line, criticized violations of democratic norms of the emerging communist regime and opposed the intrusion of the state onto private property. Apart from journalism, one of its most potent means of critique was political satire, which reached its peak in a slender series of commentaries on public processes at the time, an example of what are published in the selected masterpiece (issue 44 from October 2, 1945). These are materials such as "Thirst for Justice", "Let's be Clean", and others.

Many of the articles in the newspaper were written in response to letters of peasants about crimes of the new regime such as the article on the front page of the selected issue "We claim there is no freedom in Bulgaria, here are facts and documents."

On the front page there is also a feuilleton piece of the writer Trifon Kunev, one of the editors of the newspaper, "Slim, little ... like camels." From September 1945 to June 1946, Trifon Kunev published in the newspaper editorials which openly and sarcastically exposed the new government and the communist party. This was the expression of "protests against the insults against men and against the violation of the most sacred domain, freedom." In March 1946 he released a selection of his articles as a separate book publication with the same title. After that, he was prosecuted, his book was confiscated by the State Security authorities, and the writer was beaten up in the editorial department of his nespaper. He was imprisened for 140 days in the Central Sofia Prison, until his election to the Sixth Grand People’s Assembly.

Only between September and December 1945, the newspaper was repeatedly stopped, confiscated, and provided with so little paper that it was forced to reduce the amount of page of its issues. In 1946, the "Zemedelsko zname" newspaper was temporarily suspended due to the publication of articles critical of the Soviet Union. The newspaper was eventually forbidden on the basis of the Supplementary Law on the Press Act from April 19, 1946.

In 1989 the party Bulgarian Agrarian National Union "Nikola Petkov" and its organ "National Agrarian Flag" were restored.

The records of Croatian-American sociologist Dinko Tomašić are deposited at the Hoover Institution Library & Archives, Stanford University. In accordance with its own themes and periodization, it covers Tomašić's public work after the Second World War, when he settled in the United States as a political émigré. The collection testifies to Tomašić's sociological research, in which he critically examined political and social phenomena of post-war communist society in Croatia and Yugoslavia. The main thesis of Tomašić's sociological theory was that the revolutionary transformation of society and the huge growth of the party-state’s power destroyed political, economic, social and cultural pluralism in the public life of the Yugoslav nations. Based on his sociological methods, and making use of results the fields of ethnography and anthropology, he believed that the source of the Yugoslav revolution derived from the specific Dinaric culture, which belonged to economically passive territories, regions where the Partisan movement secured the great support, such as Montenegro, Dalmatia, Lika, Bosnia and Herzegovina. 

The Commission for Ideological and Political Work of the People's Youth of Croatia (1945-1962) was crucial in the development of young people regarding their guidance and education based on socialist values. The Commission worked under the aegis of the Communist Party, and its primary task was to monitor all activities that were opposed to the regime. Therefore, the numerous documents in this collection encompassing the period from 1945 to 1962 show different oppositional aspirations and activities of young people in Croatia in the immediate post-war period up to the beginning of the 1960s.
