Understanding Genetic Affinity: Why Bulgarians are More Closely Related to Albanians than to Serbs

The genetic makeup of Southeastern Europeans is a complex tapestry, shaped by millennia of migration, conquest, and intermarriage. The relationship between Bulgarians and Albanians is a prime example of this genetic complexity, especially when compared to their closer Slavic neighbors, the Serbs. This article delves into the historical narrative and genetic evidence that explain this phenomenon.

Historical Migration and Genetic Distance

Slavic peoples who settled in the Balkans originated from two distinct groups. Bulgarians trace their roots to east Slavic tribes from Russia and Ukraine, while Serbs, Croats, and Bosniaks descended from west Slavic tribes clustered around Poland and Czechoslovakia. This inherent genetic difference laid the groundwork for why Bulgarians and Albanians share a closer genetic bond than Bulgarians and Serbs do.

Bulgarian Migration

The journey of Bulgarians in the region began with the Slavic migration southward, which was marked by significant genetic shifts. Before the arrival of the Slavs, the Balkans hosted a diverse array of indigenous and migratory populations. Genetic studies indicate the presence of yDNA R1b from the ancient Arban/Pelasgian tribes, as well as J2 from Sephardic Jewish and Mycenaean Greek populations who arrived after 1700 BC from the Middle East. The Illyrians, whose genetic makeup included EV13, arrived with the Celtic-Illyrian invasion around 1200 BC, adding another layer to the genetic mosaic.

By the 4th century AD, Slavic tribes, particularly those of yDNA I2R1A, began to infiltrate the region. The Bulgars, a Turkic-speaking group with Slavic cultural traits, arrived around 500–600 AD, ultimately settling in Moldova, Romania, Bulgaria, Macedonia, Albania, and Greece. This migration process is crucial to understanding why Bulgarians share a closer genetic affinity with these Balkan peoples, especially Albanians, due to their similar Slavic heritage.

Genetic Composition of the Balkans

The genetic landscape of the Balkans reveals a diverse tapestry of influences. Eastward, the higher prevalence of J2 and Arvanitic genetic markers can be observed, while westward, the genetic makeup is more influenced by Celtic-Illyrian and Doric heritage. The Bulgarians, with their east Slavic roots, fall somewhere in between these genetic pools, leading to their closer genetic ties to Albanians, Romanians, Moldovans, and Macedonians.

Albanian Genetic Influence

Albanians, with their distinct cultural identity, share a genetic connection with Bulgarians due to their shared Slavic and indigenous Balkanic origins. Both groups underwent significant Slavic assimilation and intermarriage, which further blurred the lines between them genetically. Additionally, the Illyrian and ancient Greek influences in Albanian DNA contribute to their genetic affinity with Bulgarians.

Serbian Genetic Distance

In contrast, the Serbs, while also Slavic, belong to a distinct west Slavic group that has evolved differently from the east Slavs. This difference in genetic roots leads to a more pronounced genetic distance between Bulgarians and Serbs than between Bulgarians and Albanians. The west Slavic inheritance in Serbs is more akin to that of Poles, Czechs, and Slovaks, which explains the genetic and cultural divergence.

Conclusion

The genetic affinity between Bulgarians and Albanians, more so than between Bulgarians and Serbs, is a result of their shared historical and cultural background. Both groups have undergone significant migration, assimilation, and intermarriage that have shaped their genetic landscapes. Understanding these historical and genetic factors helps shed light on the complex and interconnected nature of Southeastern European populations.
