Here is an example of what “tribal” means in some Arabic societies, and how completely different it is from modern American society:,
A US Army soldier was stationed a couple years ago in Afghanistan. He was a skilled electronics technician whose job was to sit at a workshop table all day and repair radio gear, etc, One day after a long, tiring shift, he was about to go back to his barracks to sleep..but a line of supply trucks pulled into the base, and this soldier was told to go unload them. Hard, heavy work-- and he muttered to himself, complaining about how it wasn’t his job, why not find somebody else to do it, etc.
Now here’s the point of the story:
A local Afghan citizen who spoke English and was employed at the base as a translator heard the soldier complaining to himself. The Afghan guy looked at the soldier with surprise, and said “why are you doing that heavy work, just because that officer over there told you to?”
And the soldier answered “what do you mean “why”? He’s the commanding officer, and he gave me the order”.
And the Afghan guy said “but he’s obviously not from your tribe–so why do you obey him?”
The officer was black, and the soldier was white…
To the local Afghan guy, who for his entire life has known only a tribal society, it was clear that the soldier and the officer were from different tribes, and therefor, it was obvious, and perfectly natural, that you don’t have to obey an order from him, To this guy,the social order is based exclusively on tribal membership, and there is no higher authority, no system of law which apply to everybody equally.

My “cite” for this story is a post I once read someplace on the internet (reddit) about 3 years ago. Obviously, the source does not meet standards we expect here at the Dope. But to me, the story has a serious ring of truth to it; it was written in first person by a soldier who included enough detail and military jargon to make it believable to me..
