At eighteen Alexander had conquered mainland Greece, was crowned King of Macedonia at twenty and by twenty-six he had made himself master of the once mighty Persian Empire. By the time of his death, aged only thirty-three, in 323BCE he was ruler of the known world and was being worshipped as a god by the Greeks, both at Babylon, where he died, and further west, among the Greek cities of the Asiatic seaboard. The fruit of a lifetime's scholarship and meticulous research, this is an outstanding biography of one of the most remarkable rulers in history.
