With Marius began the third phase in the development of the Roman power, the Republic of the Military Commanders. For now began a period in which the leaders of the paid legions fought for the mastery of the Roman world. Against Marius was pitted the aristocratic Sulla who had served under him in Africa. Each in turn made a great massacre of his political opponents. Men were proscribed and executed by the thousand, and their estates were sold. After the bloody rivalry of these two and the horror of the revolt of Spartacus, came a phase in which Lucullus and Pompey the Great and Crassus and Julius Caesar were the masters of armies and dominated affairs. It was Crassus who defeated Spartacus. Lucullus conquered Asia Minor and penetrated to Armenia, and retired with great wealth into private life. Crassus thrusting further invaded Persia and was defeated and slain by the Parthians. After a long rivalry Pompey was defeated by Julius Caesar (48 B.C.) and murdered in Egypt, leaving Julius Caesar sole master of the Roman world.
The figure of Julius Caesar is one that has stirred the human imagination out of all proportion to its merit or true importance. He has become a legend and a symbol. For us he is chiefly important as marking the transition from the phase of military adventurers to the beginning of the fourth stage in Roman expansion, the Early Empire. For in spite of the profoundest economic and political convulsions, in spite of civil war and social degeneration, throughout all this time the boundaries of the Roman state crept outward and continued to creep outward to their maximum about 100 A.D. There had been something like an ebb during the doubtful phases of the Second Punic War, and again a manifest loss of vigour before the reconstruction of the army by Marius. The revolt of Spartacus marked a third phase. Julius Caesar made his reputation as a military leader in Gaul, which is now France and Belgium. (The chief tribes inhabiting this country belonged to the same Celtic people as the Gauls who had occupied north Italy for a time, and who had afterwards raided into Asia Minor and settled down as the Galatians.) Caesar drove back a German invasion of Gaul and added all that country to the empire, and he twice crossed the Straits of Dover into Britain (55 and 54 B.C.), where however he made no permanent conquest. Meanwhile Pompey the Great was consolidating Roman conquests that reached in the east to the Caspian Sea.
At this time, the middle of the first century B.C., the Roman Senate was still the nominal centre of the Roman government, appointing consuls and other officials, granting powers and the like; and a number of politicians, among whom Cicero was an outstanding figure, were struggling to preserve the great traditions of republican Rome and to maintain respect for its laws. But the spirit of citizenship had gone from Italy with the wasting away of the free farmers; it was a land now of slaves and impoverished men with neither the understanding nor the desire for freedom. There was nothing whatever behind these republican leaders in the Senate, while behind the great adventurers they feared and desired to control were the legions. Over the heads of the Senate Crassus and Pompey and Caesar divided the rule of the Empire between them (The First Triumvirate). When presently Crassus was killed at distant Carrhae by the Parthians, Pompey and Caesar fell out. Pompey took up the republican side, and laws were passed to bring Caesar to trial for his breaches of law and his disobedience to the decrees of the Senate.
It was illegal for a general to bring his troops out of the boundary of his command, and the boundary between Caesar’s command and Italy was the Rubicon. In 49 B.C. he crossed the Rubicon, saying “The die is cast” and marched upon Pompey and Rome.
It had been the custom in Rome in the past, in periods of military extremity, to elect a “dictator” with practically unlimited powers to rule through the crisis. After his overthrow of Pompey, Caesar was made dictator first for ten years and then (in 45 B.C.) for life. In effect he was made monarch of the empire for life. There was talk of a king, a word abhorrent to Rome since the expulsion of the Etruscans five centuries before. Caesar refused to be king, but adopted throne and sceptre. After his defeat of Pompey, Caesar had gone on into Egypt and had made love to Cleopatra, the last of the Ptolemies, the goddess queen of Egypt. She seems to have turned his head very completely. He had brought back to Rome the Egyptian idea of a god-king. His statue was set up in a temple with an inscription “To the Unconquerable God.” The expiring republicanism of Rome flared up in a last protest, and Caesar was stabbed to death in the Senate at the foot of the statue of his murdered rival, Pompey the Great.
Thirteen years more of this conflict of ambitious personalities followed. There was a second Triumvirate of Lepidus, Mark Antony and Octavian Caesar, the latter the nephew of Julius Caesar. Octavian like his uncle took the poorer, hardier western provinces where the best legions were recruited. In 31 B.C., he defeated Mark Antony, his only serious rival, at the naval battle of Actium, and made himself sole master of the Roman world. But Octavian was a man of different quality altogether from Julius Caesar. He had no foolish craving to be God or King. He had no queen-lover that he wished to dazzle. He restored freedom to the Senate and people of Rome. He declined to be dictator. The grateful Senate in return gave him the reality instead of the forms of power. He was to be called not King indeed, but “Princeps” and “Augustus.” He became Augustus Caesar, the first of the Roman emperors (27 B.C. to 14 A.D.).
He was followed by Tiberius Caesar (14 to 37 A.D.) and he by others, Caligula, Claudius, Nero and so on up to Trajan (98 A.D.), Hadrian (117 A.D.), Antonius Pius (138 A.D.) and Marcus Aurelius (161-180 A.D.). All these emperors were emperors of the legions. The soldiers made them, and some the soldiers destroyed. Gradually the Senate fades out of Roman history, and the emperor and his administrative officials replace it. The boundaries of the empire crept forward now to their utmost limits. Most of Britain was added to the empire, Transylvania was brought in as a new province, Dacia; Trajan crossed the Euphrates. Hadrian had an idea that reminds us at once of what had happened at the other end of the old world. Like Shi-Hwang-ti he built walls against the northern barbarians; one across Britain and a palisade between the Rhine and the Danube. He abandoned some of the acquisitions of Trajan. 2 The expansion of the Roman Empire was at an end.
XXXIV. Between Rome and China
THE SECOND and first centuries B.C. mark a new phase in the history of mankind. Mesopotamia and the eastern Mediterranean are no longer the centre of interest. Both Mesopotamia and Egypt were still fertile, populous and fairly prosperous, but they were no longer the dominant regions of the world. Power had drifted to the west and to the east. Two great empires now dominated the world, this new Roman Empire and the renascent Empire of China. Rome extended its power to the Euphrates, but it was never able to get beyond that boundary. It was too remote. Beyond the Euphrates the former Persian and Indian dominions of the Seleucids fell under a number of new masters. China, now under the Han dynasty, which had replaced the Ts’in dynasty at the death of Shi-Hwang-ti, had extended its power across Tibet and over the high mountain passes of the Pamirs into western Turkestan. But there, too, it reached its extremes. Beyond was too far.
China at this time was the greatest, best organized and most civilized political system in the world. It was superior in area and population to the Roman Empire at its zenith. It was possible then for these two vast systems to flourish in the same world at the same time in almost complete ignorance of each other. The means of communication both by sea and land was not yet sufficiently developed and organized for them to come to a direct clash.
Yet they reacted upon each other in a very remarkable way, and their influence upon the fate of the regions that lay between them, upon central Asia and India, was profound. A certain amount of trade trickled through, by camel caravans across Persia, for example, and by coasting ships by way of India and the Red Sea. In 66 B.C. Roman troops under Propey followed in the footsteps of Alexander the Great, and marched up the eastern shores of the Caspian Sea. In 102 A.D. a Chinese expeditionary force under Pan Chau reached the Caspian, and sent emissaries to report upon the power of Rome. But many centuries were still to pass before definite knowledge and direct intercourse were to link the great parallel worlds of Europe and Eastern Asia.
