the ironic thing is Bulgarian people are descendants of people from iran......
Pardon me? Most Bulgarians are Slavs and Macedonians. If you are refering to the Bulghars who invaded and ruled, giving a new character, then you are still wrong. The Bulghars were Oghuric Turks. Like the Volga Bulghars, the Sabirs, and Khazars they spoke a Lir Turkic dialect. Chuvash, the language of the Volga Bulghars is still spoken today. Perhaps you are thinking of the Sarmatians and Alans?

[Verginius Rufus]

The Bulgarian name comes from the Bulgars who ruled the area in the Middle Ages but were apparently a tiny minority ruling over unrelated people--the Bulgarian language is Slavic (closely related to Serbian) but probably the Slavs absorbed remnants of earlier populations in the area (Thracians, Romans, etc.).

Bulgarian, Macedonian, Albanian, and Romanian all share the feature of having the definite article as a suffix at the end of a noun--Bulgarian and Macedonian are very similar but Albanian and Romanian are only distantly related languages, so the common feature (not found in Greek or Serbian) is probably inherited from an earlier population in the region...which would suggest that when the Slavs invaded they didn't kill off all the earlier inhabitants but intermarried with them.
