Through Balkans, Islam and Italians

Bulgarian Turks are the descendants of Turkish settlers who entered the region after the Ottoman conquest of the Balkans in the late 14th and early 15th centuries, as well as Bulgarian converts to Islam who became Turkified during the centuries of Ottoman rule. However, it has also been suggested that some Turks living today in Bulgaria may be direct ethnic descendants of earlier medieval Pecheneg, Oghuz, and Cuman Turkic tribes. According to local tradition, following a resettlement policy Karamanid Turks (mainly from the Konya Vilayet, Nevşehir Vilayet and Niğde Vilayet of the Karaman Province) were settled mainly in the Kardzhali area by the sultans Mehmed the Conqueror, Selim and Mahmud II. The Turkish community became an ethnic minority when the Principality of Bulgaria was established after the Russo-Turkish War of 1877–78. This community is of Turkish ethnic consciousness and differs from the majority Bulgarian ethnicity and the rest of the Bulgarian nation by its own language, religion, culture, customs, and traditions.

Genetic origins

DNA research investigating the three largest population groups in Bulgaria: Bulgarians, Turks and Roma confirms with Y-chromosomal analysis on STR that there are significant differences between the three ethnic groups. The study revealed a high number of population-specific haplotypes, 54 haplotypes among 63 tested Turkish males from the Bulgarian DNA bank and fathers from routine paternity cases born in various geographical regions of Bulgaria. The haplotypes of the Turks from Bulgaria as converted to haplogroups make up the following frequencies: J2 (18%), I2 (13%), E (13%), H (11%), R1a (10%), R1b (8%), I1 (6%), J1 (6%), G (6%), N (5%), Q (3%).

A Y-DNA genetic study on Slavic peoples and some of their neighbours published two statistical distributions of distance because of the volume of details studied, based on pairwise FST values, the Turks from Bulgaria are most related to Anatolian Turks, thereafter to Italians, Bulgarians and others; while according to the RST values, the Turks from Bulgaria are most related to Bulgarians, thereafter to Macedonians, Anatolian Turks, Serbs and the rest, while Balts and North Slavs remain most unrelated according to them both. The study claims that the FST genetic distances reflect interpopulation relationships between the compared populations much better than their stepwise-based analogues, but that at the same time the genetic variation was more profoundly calculated by RST. FST and RST calculate allele (haplotype or microsatellite) frequencies among populations and the distribution of evolutionary distances among alleles. RST is based on the number of repeat differences between alleles at each microsatellite locus and is proposed to be better for most typical sample sizes, when data consist of variation at microsatellite loci or of nucleotide sequence (haplotype) information, the method may be unreliable unless a large number of loci are used. A nonsignificant test suggests that FST should be preferred or when there is high gene flow within populations, FST calculations are based on allele identity, it is likely to perform better than counterparts based on allele size information, the method depends on mutation rate, sometimes can likely provide biased estimate, but RST will not perform necessarily better. A Bulgarian and other population studies observed concluded that when there is not much differentiation, both statistical means show similar results, otherwise RST is often superior to the FST. However, no procedure has been developed to date for testing whether single-locus RST and FST estimates are significantly different.
