This thesis will explore the oral intangible cultural heritage of the Derventa region. Derventa is a city in Bosnia and Herzegovina. Three constituent peoples live in this area, namely Croatian, Bosnian and Serbian. Mass emigration took place before the 1992 war and most of them moved to the Republic of Croatia. The purpose of this paper is to record and preserve the oral tradition of still living native speakers. The original speakers are: Ruža Macan b. Prgomet (April 12, 1944) was born in the village of Gornja Bišnja, where she married and lived until 1992. She finished 4 grades of elementary school. Before the war, she moved to Zagreb with her family, where she still lives today. Nikola Vrdoljak (Nino) (July 30, 1930) was born and lived in the village of Gornja Bišnja not far from Derventa until 1992. After graduating from high school, he completed various courses and thus reached a higher administrative level. Anđa Sokolović born Arambašić (November 22, 1959) was born in the village of Modran and married and moved to the village of Kuljenovce. She finished eight grades of primary school, in 1992 she moved to Lučko where she is still a housewife, mother and grandmother. In this paper you will be able to find recipes for traditional dishes and drinks and various customs, the look of traditional folk costumes and various games that were once played, and native speakers have the greatest desire to still be passed down from generation to generation.
