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.).
Archelaus of Cappadocia
When Octavian became the first Roman Emperor Augustus, Archelaus became an important client monarch to Rome, and Augustus considered Archelaus loyal. Augustus had no commitment to provincialization as a matter of policy. In 25 BC, Augustus assigned Archelaus to rule Cilicia Trachea, the harbor city of Elaiussa Sebaste, as well as parts of the surrounding Cilician coast and Armenia Minor. By giving Archelaus all these extra territories to govern, Augustus was able to eliminate piracy and build a more solid bulwark against Parthia.
