Slovakia in the Roman era
The reign of Augustus (27 BC - 14 AD) began a long period known as the Pax Romana, or Roman peace. Despite continuous wars on the frontiers, and one year-long civil war over the imperial succession, the Mediterranean world remained at peace for more than two centuries. Augustus enlarged the empire dramatically, annexing Egypt, Dalmatia, Pannonia, and Raetia, expanded possessions in Africa, and completed the conquest of Hispania.
By the end of his reign, the armies of Augustus had conquered the Alpine regions of Raetia and Noricum (modern Switzerland, Bavaria, Austria, Slovenia), Illyricum and Pannonia (modern Albania, Croatia, Hungary, Serbia, etc.).
Ancient Rome
In 27 BC and at the age of 36, Octavian was the sole Roman leader. In that year, he took the name "Augustus". That event is usually taken by historians as the beginning of Roman Empire—although Rome was an "imperial" state since 146 BC, when Carthage was razed by Scipio Aemilianus and Greece was conquered by Lucius Mummius. Officially, the government was republican, but Augustus assumed absolute powers. His reform of the government brought about a two-century period colloquially referred to by Romans as the Pax Romana.
