u'know, some bulgar tribes (utigurs) fell under the rule of the western turkic khaganate

so imagine the western turkic khaganate showing some other nation (idk, china or persia maybe) stuff around, such as which tribes live in his place.

they walk by khazar, whos doing something idk maybe tending to his horse.

'so this is khazar, he's rlly determined and ruthless. pretty useful on the battlefield.'

they keep on walking and they spot bulgar (aka future old great bulgaria) in the distance on a horse.

'and this guy... we don't talk about him.'

bulgar, from distance: 'U'KNOW WHAT ELSE WE DON'T TALK ABOUT? BULGAR YOGUUUURT!' *rears his horse* 'WOOOOOOOOOOOOOO!'
