Alexander went to Asia with the intention of seizing upon the empire of the Persian king. This he accomplished, not in a wild orgy of victory but with the tenacious perseverance which took three years for the conquest and organisation of the Eastern provinces, but did not overleap itself by extravagant ambitions. It is only legend that makes him the conqueror of the world. He was a Macedonian, the hereditary king of a feudal state which the energy of his father had transformed into a military monarchy. He was a Greek in the sense which even the journalists had long since learned to express by saying that it was not race but education that made the Greek. But he was also recognised as the legitimate successor of the Achæmenides, and was himself willing to employ the Persians, side by side with Macedonians and Hellenes, in the service of the empire. His empire was accordingly not to be based on nationality, it was to rear itself over the heads of nations and states. He granted self-government in the widest interpretation of the term to kingdoms, half-civilised tribes, Hellenic and other towns; he not only respected all local peculiarities of manners and religion, he even went so far in this direction as to deliver peoples from a foreign yoke—as for instance in the case of the Egyptians. But his empire was to be more than a confederacy, it was to be an effective entity with the imperial rule supreme over all, with the imperial army a ready instrument of war in the hands of the sovereign, to compel the Universal Peace, as he called his empire, and with the king’s officers able to exercise sufficient authority for the protection, not only of the constituent parts of the empire against one another but also of the individual against the arbitrary action of the individual community. Finally, he realised the civilising mission of the state as fully as any prince has ever realised it; he took in hand the irrigation of Mesopotamia, founded cities, built harbours, and set about the scientific exploration of his newly discovered world in a style to which even the present furnishes few parallels.
