I wish history recorded the why behind the major armed conflict between clans

I think there may be some details of this conflict somewhere, but I haven't try to dig deeper into this subject.

The same concept should work today. Perhaps blockchain technology will allow for better accountability and make corruption more difficult to grow. Then such leaders would be more easily removed and more quickly too.

That's my dream too, and I think as we see more and more freedom and decentralized power (tyrannies -> feudalism -> democracy -> direct democracy ???) we'll see systems like that emerging in few places in the world and finally dominating it! Propably not in our lifetime though ;)
