They lived in mixed tribes, especially in the north of the Black Sea.
They created cultural similarities.
The Goths adapted their alphabet from the Gokturk alphabet.
The Goths took their religion, rituals, festivals and special pagan celebrations that are still celebrated from the Turks.
However, the Goths always outnumbered the Turks.
For this reason, over time, most of the Turkish tribes melted and assimilated into the Goth tribes.
This happened not only in the Balkans, but throughout Europe.
The great Turkish wars in Europe always included Goth tribes in their raids.
Famous Gothic tribes, Vandals, Lombards, Franks, and others sometimes became soldiers of powerful Turkish states, and sometimes vice versa.
However, the only people left behind from the great Turkish presence in Europe were the Hungarians, Gagauz, Karaite Turks, Finns and Lapps.
They continued to remain within the Turkish language family.
In the early days of Bulgarian Turks, their names were Turkish.
They gave many brides to Byzantium.
Naturally, they left pagan influences on Eastern Rome.
For example, the famous Byzantine flag actually emerged under the influence of Bulgarian Turks.
The meaning of the symbols and their equivalents on that flag is the same throughout Central Asia.
