The Vidovdan massacres of Serbs of Mostar.

Conditionally referred to as “Vidovdan” massacres, the killings and deportations of Serbs in Mostar mostly occurred during June, July, and August of 1941 (with a particularly high number of incidents around Vidovdan). A total of 1,024 individuals were killed, with 649 in the city itself and 331 in surrounding villages. Besides direct killings “at the doorstep,” the most common fate was transportation and liquidation in Ustasha camps throughout the Independent State of Croatia. The highest number of casualties occurred in the complex of Ustasha camps in Gospić-Jadovno-Pag and in Jasenovac. Some of the Serbs from Mostar were forcibly expelled to Serbia.

Numerous families suffered in villages around Mostar, such as Baćevići (Sudar, Golo, Savić, Škoro), Goranci (Matković, Ivanišević), Žitomislići (Gačić, Golo, Ljoljić, Svrdlin, Simić, Sjeran), as well as in settlements like Buna, Malo Polje, Hodbina, Lakiševina, Slipčići, Raštani, Ortiješ, Bijelo Polje, Vrapčići, Raška Gora, Donja Drežnica, and others.
