The generals of Alexander met in dismay and grief the morning after his death at Babylon, and Perdiccas sadly laid the ring on the empty throne. There was no one to go on with what he had begun, for though he had a brother named Arridæus, the poor youth was weak in mind; and Alexander’s own son was a little, helpless infant.  These two were joined together as Kings of Macedon and Shahs of Persia, and four guardians were appointed for them, who really only used their names as a means of getting power for themselves.
