Now that Darius was dead, Alexander took the Persian title of “Shah in Shah” (king of kings), and became ruler of all the empire which had been subject to the Persian monarch.
He was so proud of his new state and of his vast conquests, that he entirely forgot that he owed them mostly to his brave generals and soldiers; and he became so obstinate, that he would no longer listen to any advice, and only thought of having his own way.
His father’s general, Parmenio, who had always given him the wisest counsel, was no longer in favor, because he tried to restrain the king’s extravagance. Indeed, Alexander’s once generous and noble nature was so changed, that, when his courtiers accused Parmenio of treachery, he listened to them, and actually put the faithful general to death.
Every day now Alexander indulged in feasts and banquets, always drinking more and more, although it was affecting his health as well as his temper. Clytus, the son of his old nurse, tried to check his excesses, but only succeeded in provoking his wrath.
On one occasion such remonstrances so enraged Alexander, that in his drunken fury he seized a spear and killed Clytus. When he saw him dead at his feet, the king realized what a terrible crime he had committed, and felt deep remorse for a short time.
He reformed, and, instead of giving himself up entirely to pleasure, spent the next two years in the work of governing Persia, where he founded several cities called by his name.
