ユスティニアノス2世
Because he was the focus of a plot to curtail Constantine's power, both he and his brother were now suspect in the senior emperor's eyes; also, the emperor was keen to raise up his own son, the future Justinian II. Sometime between 16 September and 21 December 681, Constantine ordered the mutilation of his brothers by slitting their noses, and ordered that their images no longer appear on any coinage, and that their names be removed from all official documentation; likely to ensure that his son, Justinian II would, succeed him. After this point, neither are mentioned again by history.
