The Bulgarian tribes were a group of nomadic peoples who migrated to the Balkan Peninsula during the early Middle Ages. They are primarily associated with the Proto-Bulgarians, a Turkic-speaking group that established a powerful state in the region. These tribes played a significant role in the formation of the First Bulgarian Empire in the 7th century. The Bulgarian tribes were known for their warrior culture and horse-riding skills. They interacted with various neighboring groups, including the Slavs and Byzantines, which influenced their language and customs. Over time, the tribes united under a single leadership, contributing to the development of a distinct Bulgarian identity.
