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.).
Julio-Claudian dynasty
Although Augustus' succession plans were all but ruined due to the deaths of more than several family members, including many of his own descendants, in the end Tiberius remained faithful to his predecessor's wishes that the next emperor would hail from the Julian side of the Imperial family. Thus, Tiberius was succeeded by Gaius Julius Caesar Augustus Germanicus, the sole-remaining son of his adopted son Germanicus. The new emperor not only belonged to both the Julian and Claudian sides of the Imperial family, but was also a direct descendant of Augustus Caesar through his mother Agrippina the Elder. More commonly remembered in history by his childhood nickname Caligula, he was the third Roman Emperor ruling from AD 37 to 41.
