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.).
Caligula
Caligula (; Latin: "Gaius Julius Caesar Augustus Germanicus"; 31 August 12 – 24 January 41 AD) was Roman emperor from AD 37 to AD 41. The son of the popular Roman general Germanicus and Augustus' granddaughter Agrippina the Elder, Caligula was born into the first ruling family of the Roman Empire, conventionally known as the Julio-Claudian dynasty. Germanicus' uncle and adoptive father, Tiberius, succeeded Augustus as emperor of Rome in AD 14.
