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.).
Julius Caesar
Because Caesar's clemency had resulted in his murder, the Second Triumvirate reinstated the practice of proscription, abandoned since Sulla. It engaged in the legally sanctioned killing of a large number of its opponents to secure funding for its 45 legions in the second civil war against Brutus and Cassius. Antony and Octavian defeated them at Philippi.
Afterward, Mark Antony formed an alliance with Caesar's lover, Cleopatra, intending to use the fabulously wealthy Egypt as a base to dominate Rome. A third civil war broke out between Octavian on one hand and Antony and Cleopatra on the other. This final civil war, culminating in the latter's defeat at Actium in 31 BC and suicide in Egypt in 30 BC, resulted in the permanent ascendancy of Octavian, who became the first Roman emperor, under the name Caesar Augustus, a name conveying religious, rather than political, authority.
