After Turkey's defeat in the war with Russia, the countries concluded the San Stefano Peace Treaty in 1878, which fundamentally changed the balance of power in the Balkans. Bulgaria, Bosnia and other regions were given greater autonomy - Bosnia became a Turkish fiefdom. The new order was not to everyone's liking. In the same year, the Congress of Berlin was convened. There was a fear that Russian dominance in the region could threaten the balance of power in Europe. As a result, the right to occupy and administer Bosnia and Herzegovina was ceded to Austria-Hungary.

In an effort to 'enlighten' and develop the local population, qualified citizens from various parts of the Austro-Hungarian monarchy, including Czechs and Poles, began to be brought into Bosnia. The latter group of engineers, bankers, lawyers, doctors and peasants numbered more than 10,000. Among them were two prominent Polish doctors - Jadwiga Olszańska and Teodora Krajewska. They were joined during the First World War by Bronisława Całczyńska-Prašek, born in Sanok in 1887.

Bronislawa Całczyńska-Prašek began her medical education at the Lviv University Medical Faculty and obtained her medical diploma at the University of Vienna in 1912, receiving the title of doctor of general medicine on the same day. After marrying a Czech, Emil Prašek in 1913, she moved to Sarajevo in 1915, where she became the city's first paediatrician. She worked in Sarajevo for several years, and moved to Zagreb in 1921, as her husband received an engagement at the Faculty of Medicine in Zagreb, where he became a lecturer in bacteriology, hygiene and, for a time, pathological anatomy.

During the Second World War, Bronislawa Całczyńska-Prašek showed extraordinary courage, being a Home Army liaison officer and actively involved in saving Jews. She also experienced a personal tragedy during this time - her son was killed by the Ushtashe. She died in Zagreb, where she was buried in Mirogoj Cemetery, together with her husband and children.
