4Tiberius (16 November, 42 BC – 16 March, 37 AD)

Tiberius was one of Rome’s greatest generals, conquering Pannonia, Dalmatia, Raetia, and temporarily, parts of Germania, laying the foundations for the northern frontier.

Despite his overwhelmingly negative image left by Roman historians, Tiberius left the imperial treasury with nearly three billion sesterces upon his death. Rather than embarking on expensive conquests, he decided to build additional bases and use diplomacy over conflict.
