The use of "shugo" lords to attack one of their own colleagues in the 1366 points to the growing authority of the shōgun, vis-a-vis the "shugo" lords, and the emergence of an effective instrument of coercion. Up until then, there was virtually no true punitive mechanisms that the shōgun could use against his "shugo" lords. In conjunction with the new intermediary instruments that emerged between the shōgun and the "shugo" lords, the new coercive instrument of pitting one "shugo" lord against another, through shōgun-"shugo" coalitions, strengthened the shōgun's hand.
