Problems finding an Heir
Contributed by David Verne
Agrippina, the widow of Germanicus, will die in prison this year, starving herself to death. Her son Drusus will be intentionally starved to death. Tiberius is left in a tight spot because he still needed someone to succeed him but has killed most of his family. There were still four of Germanicus' children alive. Three daughters, who were married off on Tiberius' orders, and a 19 year old son, Gaius Julius Caesar, whose nickname was Caligula. Caligula was invited to live with Tiberius in 31 AD and managed to survive by hiding any resentment and acting as a loyal servant to the emperor.
