That's a hard one to answer but from all my reading it would seem there was one main reason. The Berbers were nomads so they never were able to be collectively together to form an army against invaders. Therefore, the Berbers were constantly being conquered by someone. Each time they had to learn new laws set out by the conquerors. When the Arabs came with their mighty army, they knew they couldn't fight so giving in was in an odd way a protection system of kinds.
peace has a different meaning for everyone. for me, peace is everything being at ease. not necessarily like the idea of world peace but simply where things are not difficult. to establish peace people should work through their problems and work together to settle their issues.
