marriages customes in gökturk era

[abdulhay]

I wonder the rituals turks had in gökturk era, I mean nowa days its usuall for cousine to marry which I think is something turks got from saudi arabians, I read that mongols have a pracitse that u should not be relative 7 generations back, is it the same with turks , did they also have this custome before islam

Exogamy (marrying someone outside your tribe) was a common practice among the Gokturks.
