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.).

The constitutional consequences of this event were, formally at least, to reverberate for more than two thousand years. Rome would never again have a hereditary "king," even if later emperors were absolute rulers in all but name. This constitutional tradition prevented both Julius Caesar and Octavian Augustus from accepting a crown; instead they had to devise a confluence of several republican offices onto their persons in order to secure absolute power. Their successors both in Rome and in Constantinople adhered to this tradition in form if not in essence, and even the office of German Holy Roman Emperor remained typically elective rather than hereditary—up to its abolition in the Napoleonic Wars, 2314 years later.
