Mradhorro (mra ˈðoː ro) was an ancient chief of a Dhecadhach tribe by the same name who lived and ruled a small kingdom during the rise of city state civilization in the Dhecodhor River valley. The name also refers directly to the kingdom he founded, which outlasted him by a few generations, in all from cir. -4600 to -4275. Mradhorro was the first civilization known to control more than a single settlement and field a standing military, setting the stage for all future Dhecadhach states.
