We can see that the Black Sea coastline is the largest, larger than the Mediterannean and Aegean coastlines. People from the Black Sea region have a culture which is unique to the rest of Turkey.

The Turkish language, is of the Turkic language group. In that group you have Turkmen, Azeri, Kazakh and many others, all of whom have Turkish ancestory. Now the Turkic languages are part of the Altaic language group. The Altay mountains, from which the name 'Altaic' comes from, is the ancesteral homeland of the Turks. Mongolian also falls under the Altaic branch.
So if you were to imagine this as a pyramid, you'd have one block on the top called 'Altaic' and two blocks under it called 'Turkic' and 'Mongolic'. Under the 'Turkic' block then you'd have all the different blocks, namely 'Turkish', 'Azeri', etc.
