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.).
Crisis of the Roman Republic
The end of the Crisis can likewise either be dated from the assassination of Julius Caesar on 15 March 44 BC, after he and Sulla had done so much "to dismantle the government of the Republic," or alternately when Octavian was granted the title of "Augustus" by the Senate in 27 BC, marking the beginning of the Roman Empire. The end could also be dated "earlier", to the time of the constitutional reforms of Julius Caesar in 49 BC.
