This book is a very clear explanation of the complex machinations of a group of early Roman leaders. The Roman Republic, which was the rule of the land for 500 years, collapsed when Julius Caesar took over Rome and created the Roman Empire. I was surprised to see that 'Pax Romana'(Roman Peace) was considered to be in place for 200 years after Caesar Augustus took the helm of Rome. It seemed that Tiberius and Caligula created lots of fear and controversy during their reigns. This is a quick look at some of the most important rulers of the Roman Empire.
