To connect the Rhine and Danube at their sources by a massive wall, to establish forts with strong garrisons at every point where these rivers could be easily forded, such were the precautions by which wise Emperors planned to shut in Rome’s civilization, and to keep out all who would lay violent hands upon it.

The Emperor Augustus left a warning to his successors that they should be content with these natural boundaries, lest in pushing forward to increase their territory they should in reality weaken their position. It is easy to agree with his views centuries afterwards, when we know that the defences of the Empire, pushed ever forward, snapped at the finish like an elastic band; but the average Roman of imperial days believed his nation equal to any strain.

It was a boast of the army that ‘Roman banners never retreat’. If then a tribe of barbarians were to succeed in fording the Danube and in surprising some outpost fort, the legions sent to punish them would clamour not merely to exact vengeance and return home, but to conquer and add the territory to the Empire. In the case of swamps or forest land the clamour might be checked; but where there was pasturage or good agricultural soil, it would be almost irresistible. Emigrants from crowded Italy would demand leave to form a colony, traders would hasten in their footsteps, and soon another responsibility of land and lives, perhaps with no natural protection of river, sea, or mountains, would be added to Rome’s burden of government. Such was the fertile province of Dacia, north of the Danube, a notable gain in territory, but yet a future source of weakness.

Government of the Roman Empire

At the head of the Empire stood the Emperor, ‘Caesar Augustus’, the commander-in-chief of the army, the supreme authority in the state, the fountain of justice, a god before whose altar every loyal Roman must burn incense and bow the knee in reverence.

It was a great change from the old days, when Rome was a republic, and her Senate, or council of leading citizens, had been responsible to the rest of the people for their good or bad government. The historian Tacitus, looking back from imperial days with a sigh of regret, says that in that happy age man could speak what was in his mind without fear of his neighbours, and draws the contrast with his own time when the Emperor’s spies wormed their way into house and tavern, paid to betray those about them to prison or death for some chance word or incautious action. Yet Rome by her conquests had brought on herself the tyranny of the Empire.

It is comparatively easy to rule a small city well, where fraud and self-seeking can be quickly detected; but when Rome began to extend her boundaries and to employ more people in the work of government, unscrupulous politicians appeared. These built up private fortunes during their term of office: they became senators, and the Senate ceased to represent the will of the people and began to govern in the interests of a small group of wealthy men. Members of their families became governors of provinces, first in Italy, and then as conquests continued, across the mountains in Gaul and Spain, and beyond the seas in Egypt and Asia Minor. Except in name, senators and governors ceased to be simple citizens and lived as princes, with officials and servants ready to carry out their slightest wish.

Perhaps it may seem odd that the Roman people, once so fond of liberty that they had driven into exile the kings who oppressed them, should afterwards let themselves be bullied or neglected by a hundred petty tyrants; but in truth the people had changed even more than the class of ‘patricians’ to whom they found themselves in bondage.

No longer pure Roman or Latin, but through conquest and intermarriage of every race from the stalwart Teuton to the supple Oriental or swarthy Egyptian, few amongst the men and women crowding the streets of Rome remembered or reverenced the traditions of her early days. Rome stood for military glory, luxury, culture, at her best for even-handed justice, but no longer for an ideal of liberty. If national pride was satisfied, and adequate food and amusement provided, the Roman populace was content to be ruled from above and to hail rival senators as masters, according to the extent of their promises and success. A failure to fulfil such promises, resulting in a lost campaign or a dearth of corn, would throw the military tyrant of the moment from his pedestal, but only to set up another in his place.

It was an easy transition from the rule of a corrupt Senate to that of an autocrat. ‘Better one tyrant than many’ was the attitude of mind of the average citizen towards Octavius Caesar, when under the title of Augustus he gathered to himself the supreme command over army and state and so became the first of the Emperors. Had he been a tactless man and shouted his triumph to the Seven Hills he would probably have fallen a victim to an assassin’s knife; but he skilfully disguised his authority and posed as being only the first magistrate of the state.
