Tensions between Nomads and Sedentary Population

The difference between tax collection, extortion or demanding tribute can sometimes be somewhat vague. In many parts of our country taxes are collected by the Nomadic Clans in ways very similar to how they would have conducted themselves during a raid.\nToday an emissary from some of our more well-to-do subjects arrived to tell a tale of how the would-be tax collectors pillaged their lands and then laid siege to their fortified homes. They now demand retribution from the our ruler and for the perpetrators to be punished. The tribes would, however, likely not take kindly to any such restrictions of their conduct.
