 Henry V had attempted in vain to mediate an amicable settlement between Burghausen and the ministerials in the dispute that led to the murder, and he also would have had a reason to resent his father's inaction.A flaw in this theory is that there was a very long time lag between the murder of Burghausen and when Henry V turned his back on his father.In November 1104, Henry V had joined his father's army on a punitive expedition against Saxon Reformers who had opposed the election of the Archbishop of Magdeburg.
