Tiberius
The last years of Tiberius were notable for his complete absence from Rome, and his inactivity as Emperor. He was now an old man in his 70s, and left decisions to the officials in Rome. He did nothing to prevent the rise of his grandnephew Caligula, who was now popular with the people (as the only surviving son of Germanicus) and who had the support of the Prefect Macro.
