Attila is indeed a national hero. The Magyars originated from the plains between the Volga and the Urals but that is only a small percentage of the DNA of most modern Hungarians. The country was all but depopulated twice by plagues, wars, etc and the rulers invited in neighboring Slavs and Germans to help repopulate it so their DNA profile looks very much like those of their neighbors. For example, there are plenty of blondes in Hungary.
The names of the days of the week from Wednesday to Saturday in Hungarian are borrowed from a Slavic language.
