[3] It is believed that the community descends from migrating merchants, miners and entrepreneurs from the Republic of Ragusa (Dubrovnik and its hinterland,[5] families Glasnović, Macukić, Ćibarić, Matić, Ivanović[1]), Bosnia and Herzegovina (families Ivanović and Brkić)[1] and Kotor[2][3][4] who settled the area in the 14th century medieval Serbia, The earliest written record of Catholics in Janjevo is a letter from Pope Benedict XI, dated 1303, which mentions the Catholic parish of St. Nicholas with its center in Janjevo.

[6] Stronger national awareness among Janjevci came in the 19th century thanks to the work of the Herzegovinian Franciscan Franjo Brkić and the teacher Jakov Slišković, as well as during the interwar period.

[1] The first one describes how in the dilbokoj planini ("deep mountain"), after a general famine, a sister and a brother lived alone, who did not know that they were related to the new Janjevo, while the second story mentions the terrible fate of people after the war and how they are the only ones Jana Palić "Nedokoljka" and one of the Glasnovićs are still alive; both stories are based on massive deaths and suffering during the Mongol invasion of the area.

On the upper part of the body, a mintan or mintanče (jacket) was worn, that is, a jelek or žamadan (vest), under which was a shirt with a lace collar.

Women did not wear skirts, but dimije, over which a richly decorated bošča (apron) was draped, and the waist was tied with a kušak (belt).

[1] Turkicisms are also belendzika (a thin oriental bracelet in a series of five to six), džam (glass), ćumbe (stove), tendžera (pot), duvar (wall).

[1] The community also celebrates Saint George's Day (known among Janjevci as Đurđevdan)[1] - an important holiday, especially for teen Janjevci who would prepare a special celebration called "rifana", which lasted all night, where mischievous bećari (guys) tried to steal the prepared food from the girls they loved and cut the rope on the swings on which they were swinging.

On the feast of St. John the Baptist, they would burn straw that children jumped over, the custom was called kalavešnica and is connected to the pre-Christian celebration of the summer solstice.

[citation needed] Janjevci families started migrating to SR Croatia, part of Yugoslavia, in the 1950s, mostly settling in Zagreb.

[3] By the beginning of the 1970s, there was a large community of Janjevci along and within the vicinity of Konjšćinska Street in Dubrava, a district in the eastern part of Zagreb.

[11] In April 2017, 196 displaced Letničani, composed of 41 families who were waiting on homes promised by the state, were finally given newly built houses in the settlement Dumače, in the municipality of Petrinja.
