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.).
History of Rome
However, the growth of the Imperium Romanum (Roman power) created new problems, and new demands, that the old political system of the Republic, with its annually elected magistrates and its sharing of power, could not solve. The dictatorship of Sulla, the extraordinary commands of Pompey Magnus, and the first triumvirate made that clear. In January 49 BC, Julius Caesar the conqueror of Gaul, marched his legions against Rome. In the following years, he vanquished his opponents, and ruled Rome for four years. After his assassination in 44 BC, the Senate tried to reestablish the Republic, but its champions, Marcus Junius Brutus (descendant of the founder of the republic) and Gaius Cassius Longinus were defeated by Caesar's lieutenant Marcus Antonius and Caesar's nephew, Octavian.
