In the winter of 180 A.D., the Roman emperor Marcus Aurelius fights to keep Germanic barbarians from invading his northern territories on the Danube frontier. His deputies are the Greek exslave Timonides, a closet Christian, and the stern and honest general Gaius Livius. Livius has close connections with the imperial family, being the lover of Aurelius philosopher daughter Lucilla and a friend of her brother Commodus. Nevertheless, he is amazed to hear that Aurelius wants to make him his heir. Despite his military obligations the emperor has egalitarian ideals, dreaming of a day when Rome grants equal rights to men of all nations. He knows that he will not live to achieve this end, and trusts Livius to do so more than his charismatic but brutal son. The discovery that his father has effectively disinherited him hurts Commodus immensely, and damages the almost brotherly relationship he had enjoyed with Livius.Aurelius summons all the governors of the Roman empire to his headquarters, intending to announce Livius future accession. Before he can do so he is poisoned by Commodus cronies, who hope to secure their own political future by putting their friend on the throne. Sure enough, Livius feels that a nonaristocrat such as himself would never be accepted as emperor without Aurelius explicit backing he lets his old friend take the position instead. Commodus, who was not part of the murder plot, is left feeling helplessly angry at his deceased father. He dedicates himself to undoing all Aurelius policies this involves blatant favoritism towards Rome and Italy, which are enriched by ferocious taxation of the provinces that were to be their equals. ........
