The sons of Caesar : Imperial Rome's first dynasty

At the heart of this history of the Julio-Claudian dynasty are the lives of six men – Julius Caesar, Augustus, Tiberius, Gaius Caligula, Claudius and Nero – men who mastered Rome and changed it from a democracy to a personal possession.

It was no easy task: Caesar and Caligula were assassinated, Nero committed suicide and Claudius was poisoned.

Only Augustus and Tiberius died natural deaths – and even that is uncertain.

The Julio-Claudian saga has a host of other characters, from Cicero, the last great statesman of the Republic, to Livia, matriarch of the Empire; the passionate Mark Antony and the scheming Sejanus; and Agrippina, mother of Nero and sister of Caligula, who probably murdered her husband and in turn was killed by her son. Set against a background of foreign wars and domestic intrigue, the story of Rome's greatest dynasty is also the story of the birth of an imperial system that shaped the Europe of today.
