With Tiberius gone, the power of Sejanus in Rome increased. Sejanus had conspired with [[Livilla]], who was Tiberius' niece and had been married to his son [[Drusus II|Drusus]], to secretly poison Drusus years before. He died in 23 A.D. Sejanus tried to have himself married to Livilla but Tiberius prevented it. Now along with Livilla, Sejanus plotted to overthrow the Emperor in favor of the Julian line with either Caligula, his grandson Tiberius Gemellus, or himself as an adopted Julian as the new Emperor. However, the plot was foiled when [[Antonia Minor|Antonia]] mother of Livilla exposed it. Sejanus' wife exposed the role of Sejanus and Livilla in the poisoning of Drusus. Tiberius had all Sejanus' supporters (mostly supporters of Tiberius' ex-wife Julia's family) rounded up and executed. Sejanus and his children were also executed. | With Tiberius gone, the power of Sejanus in Rome increased.
