Patrice Lumumba was the first prime minister of independent Congo and was assassinated in 1961, only 67 days after taking office. This event triggered protests in Belgrade which fast grew into larger clashes between the demonstrators and police. The biggest riot took place at Tašmajdan Park. The police used water cannon against the protestors. Thirty-five protestors, 51 police officers and nine members of the fire brigade were hurt. The demonstrations were mainly organised in front of the Belgian embassy since it was believed that Belgium, the former colonial power in Congo, had orchestrated the murder. The demonstrators took over and ransacked the embassy. These events in front of the Belgian embassy in Belgrade were recorded and documented in the photographs of Tomislav Peternek, at that time a reporter with the newspaper ‘Borba’. The police used the opportunity to confiscate his films, but later returned them.   

The Sanda Stolojan Collection is an important source of documentation for understanding and writing the history of that particular segment of the Romanian exile community which was actively involved in the West in unmasking the communist regime in Romania. At the same time, this private archive contributes to an understanding of Romanian–French bilateral relations between 1968 and 1998. In particular, the collection illustrates the activity of the collector and other personalities of the exile aimed at promoting respect for human rights in Romania and stopping the demolitions imposed by the communist authorities as part of Bucharest's systematisation programme, and later at supporting the reconstruction of democracy in their country of origin.

The Ion Dumitru Collection is the richest and most diverse of all the private archives of the Romanian exile community, which makes it indispensable for the study of the history of postwar Romanian exile. The collection is also a fundamental source for documenting and understanding Romania's (domestic and foreign) political, cultural, economic, and social evolution during both the communist and post-communist periods. At the same time, this private archive is a historical source both for understanding how the Bucharest authorities acted to divide the Romanians abroad and to counteract their actions aimed at unmasking the wrondoings of the communist regime between 1948 and 1989 in the West and for how Romanians within the country perceived the emigrant community.

Kljaković wrote this autobiographical political-utopian novel during his émigré period in Rome. He dealt with the crisis of the ideological focal points of his time through the prism of real and fictitious situations, in which Kljaković stood out in particular by sharply rejecting communist ideology. Kljaković's novel was inspired by the 1956 Hungarian Revolution. For this reason, the central character is named Oskar Csokor, who suffered at communist hands in Hungary in 1956. Likewise, the very title of the novel refers to the emergence and spread of communism as a "bloody wave" that flooded the entire world of its time. The book was banned in the socialist period, so its second edition was only published in Croatia in 2011.
