Antipater (Farewell, Great Macedon)
Antipater was a Greek politician in the court of Alexander the Great. Towards the end of his life, he masterminded a plot to instate Seleucus as the King of Macedon, dying himself in the process.
From May to June of 323 BC, Antipater arrived in Babylon as part of Alexander's army. While there, Antipater and his co-conspirators, Iollas and Glaucias, he arranged the murders of Alexander's generals and heirs, Cleitus, Calanus and Hephaestion. He accused the First Doctor, Ian Chesterton, Barbara Wright and Susan Foreman of these murders, causing Alexander to have them imprisoned. Finally, he poisoned Alexander's drink during the mourning ceremonies of Hephaestion, whereupon his plot was discovered. He was murdered by Seleucus before his part could be exposed to the dying Alexander. (AUDIO: Farewell, Great Macedon)
