The whole country, in a word, felt so much confidence in the wisdom, the justice, and the moderation of Antipater, that they submitted very readily to his sway during the absence of Alexander. Olympias, however, caused him continual trouble. In the exercise of his regency, he governed the country as he thought his duty to the people of the realm and to Alexander required, without yielding at all to the demands or expectations of Olympias. She, consequently, finding that he was unmanageable, did all in her power to embarrass him in his plans, and to thwart and circumvent him. She wrote letters continually to Alexander, complaining incessantly of his conduct, sometimes misrepresenting occurrences which had actually taken place, and sometimes making accusations wholly groundless and untrue. Antipater, in the same manner, in his letters to Alexander, complained of the interference of Olympias, and of the trouble and embarrassment which her conduct occasioned him. Alexander succeeded for a season in settling these difficulties more or less perfectly, from time to time, as they arose; but at last he concluded to make a change in the regency. Accordingly, on an occasion when a considerable body of new recruits from Macedon was to be marched into Asia, Alexander ordered Antipater to accompany them, and, at the same time, he sent home another general named Craterus, in charge of a body of troops from Asia, whose term of service had expired.[C] His plan was to retain Antipater in his service in Asia, and to give to Craterus the government of Macedon, thinking it possible, perhaps, that Craterus might agree better with Olympias than Antipater had done. [Footnote C: For the route from Macedonia to Babylon, see map.] Antipater was not to leave Macedon until Craterus should arrive there; and while Craterus was on his journey, Alexander suddenly died. This event changed the whole aspect of affairs throughout the empire, and led to a series of very important events, which followed each other in rapid succession, and which were the means of affecting the condition and the fortunes of Olympias in a very material manner. The state of the case was substantially thus. The story forms quite a complicated plot, which it will require close attention on the part of the reader clearly to comprehend.
