He had three sons who might be considered as heirs to his throne--Darius, Hystaspes, and Artaxerxes. Hystaspes was absent in a neighboring province. The others were at home. He had also a very prominent officer in his court, whose name, Artabanus, was the same with that of the uncle who had so strongly attempted to dissuade him from undertaking the conquest of Greece. Artabanus the uncle disappears finally from view at the time when Xerxes dismissed him to return to Susa at the first crossing of the Hellespont. This second Artabanus was the captain of the king's body-guard and, consequently, the common executioner of the despot's decrees. Being thus established in his palace, surrounded by his family, and protected by Artabanus and his guard, the monarch felt that all his toils and dangers were over, and that there was nothing now before him but a life of ease, of pleasure, and of safety. Instead of this, he was, in fact, in the most imminent danger. Artabanus was already plotting his destruction. One day, in the midst of one of his carousals, he became angry with his oldest son Darius for some cause, and gave Artabanus an order to kill him. Artabanus neglected to obey this order. The king had been excited with wine when he gave it, and Artabanus supposed that all recollection of the command would pass away from his mind with the excitement that occasioned it. The king did not, however, so readily forget. The next day he demanded why his order had not been obeyed. Artabanus now began to fear for his own safety, and he determined to proceed at once to the execution of a plan which he had long been revolving, of destroying the whole of Xerxes's family, and placing himself on the throne in their stead. He contrived to bring the king's chamberlain into his schemes, and, with the connivance and aid of this officer, he went at night into the king's bed-chamber, and murdered the monarch in his sleep. Leaving the bloody weapon with which the deed had been perpetrated by the side of the victim, Artabanus went immediately into the bed-chamber of Artaxerxes, the youngest son, and, awaking him suddenly, he told him, with tones of voice and looks expressive of great excitement and alarm, that his father had been killed, and that it was his brother Darius that had killed him. "His motive is," continued Artabanus, "to obtain the throne, and, to make the more sure of an undisturbed possession of it, he is intending to murder you next. Rise, therefore, and defend your life." Artaxerxes was aroused to a sudden and uncontrollable paroxysm of anger at this intelligence. He seized his weapon, and rushed into the apartment of his innocent brother, and slew him on the spot. Other summary assassinations of a similar kind followed in this complicated tragedy. Among the victims, Artabanus and all his adherents were slain, and at length Artaxerxes took quiet possession of the throne, and reigned in his father's stead. THE END.
