Tran, Bulgaria in the context of "Bulgarian resistance movement during World War II"

The Transitional Bulgarian dialects are a group of Bulgarian dialects, whose speakers are located west of the yat boundary and are part of the Western Bulgarian dialects. As they have most of the typical characteristics of the North-Western Bulgarian dialects, they are sometimes classified as belonging to this subgroup under the name of Extreme North-Western dialects. On Bulgarian territory, the Transitional dialects occupy a narrow strip of land along the Bulgarian border with Serbia, including the regions of Tran, Breznik, Godech, Chiprovtsi and Belogradchik. They also cross the border to include the dialects or subdialects of the Bulgarian minority in the Western Outlands (the regions of Tsaribrod and Bosilegrad). The Transitional dialects are part of the Torlak dialectal group also spoken in southeastern Serbia and North Macedonia and are part of the gradual transition from Bulgarian to Serbian. The Bulgarian Transitional dialects and the Serbian Prizren-Timok dialects are loosely characterised by mixed, predominantly Serbian phonology and predominantly Bulgarian morphology. The features described here are characteristic only of the Transitional dialects within Bulgaria.

Shopi or Šopi (South Slavic: Шопи) is a regional term, used by a group of people in the Balkans. The areas traditionally inhabited by the Shopi or Šopi is called Shopluk or Šopluk (Шоплук), a mesoregion. Most of the region is located in Western Bulgaria, with smaller parts in Eastern Serbia and Eastern North Macedonia, where the borders of the three countries meet.

The majority of the Shopi (those in Bulgaria, as well in the Bulgarian territories annexed by Serbia in 1919) identify as Bulgarians, those in the pre-1919 territory of Serbia—as Serbs and those in North Macedonia—as ethnic Macedonians.

Greben (Cyrillic: Гребен, meaning "ridge" or literally "comb") is a mountain in southeastern Serbia, with a small section of the southwestern ridge in Bulgaria. It is named after a large karst ridge that runs along its spine. Greben rises near the village of Poganovo in Serbia, in the municipality of Dimitrovgrad, and extends southeast towards the Bulgarian village of Vrabcha. Prior to the Treaty of Neuilly of 1919, after the First World War, the area was part of Bulgaria.

Its highest peak Beženište (or Dziglina livada) stands at an elevation of 1,338 meters above sea level. The highest peak that falls within Bulgaria is Dragovski kamak (Драговски камък), at 1,118 m. Due to the characteristic pyramidal shape of its north face, Dragovski kamak is referred to as the "Matterhorn of Tran".
