What cased tiberius downfall?

Answer 1

Tiberius is a man who needs a lot of studying. We get the views of the aristocrats as to his rule, and they were the ones who suffered in one way or another, so naturally nothing good will be said about him. His unpopularity was mainly because of his dour personality and his misplaced trust in Sejanus. Sejanus ruled Rome in Tiberius' absence with an iron fist, gathering allies and power for himself, with the deaths of many nobles on trumphed up charges. When Tiberius, who was living on Capri, was informed of what was going on, he took measures to rid himself of Sejanus and all Sejanus' followers and more deaths took place. These purges, were both blamed on Tiberius and he was hated. However, looking at the empire as a whole, Tiberius was one of the better emperors. The treasury was full and there were no major wars and the borders were secure.
