Long before George R.R. Martin penned his tale of war, intrigue and treachery the ancient world was scene to its own version of The Game of Thrones.
When Alexander the Great died in Babylon 323 BC, he left the greatest empire the world had yet seen with no clear successor. While both of his wives (Roxane the daughter of Oxyartes of Bactria; and Stateira , daughter of Darius) were pregnant, he had no (legitimate) children yet born; though a four year old son of his former mistress Barsiné, named Heracles, was claimed by some to be Alexander’s illegitimate son. Alexander had made no provision for what was to happen in the case of his death. For a ruler who habitually took unnecessary risks; leading his Army, literally, from the front this was particularly irresponsible. But it was completely in character for Alexander, who ever refused to acknowledge his own mortality.
