Youth and apprenticeship

When he was born, his paternal grandfather was already consul for the second time and prefect of Rome, which was the crown of prestige in a senatorial career; his father’s sister was married to the man who was destined to become the next emperor and whom he himself would in due time succeed; and his maternal grandmother was heiress to one of the most massive of Roman fortunes. Marcus thus was related to several of the most prominent families of the new Roman establishment, which had consolidated its social and political power under the Flavian emperors (69–96), and, indeed, the ethos of that establishment is relevant to his own actions and attitudes. The governing class of the first age of the Roman Empire, the Julio-Claudian, had been little different from that of the late Republic: it was urban Roman (despising outsiders), extravagant, cynical, and amoral. The new establishment, however, was largely of municipal and provincial origin—as were its emperors—cultivating sobriety and good works and turning more and more to piety and religiosity.

The child Marcus was thus clearly destined for social distinction. How he came to the throne, however, remains a mystery. In 136 the emperor Hadrian (reigned 117–138) inexplicably announced as his eventual successor a certain Lucius Ceionius Commodus (henceforth L. Aelius Caesar), and in that same year young Marcus was engaged to Ceionia Fabia, the daughter of Commodus. Early in 138, however, Commodus died, and later, after the death of Hadrian, the engagement was annulled. Hadrian then adopted Titus Aurelius Antoninus (the husband of Marcus’s aunt) to succeed him as the emperor Antoninus Pius (reigned 138–161), arranging that Antoninus should adopt as his sons two young men—one the son of Commodus and the other Marcus, whose name was then changed to Marcus Aelius Aurelius Verus. Marcus thus was marked out as a future joint emperor at the age of just under 17, though, as it turned out, he was not to succeed until his 40th year. It is sometimes assumed that in Hadrian’s mind both Commodus and Antoninus Pius were merely to be “place warmers” for one or both of these youths.

The long years of Marcus’s apprenticeship under Antoninus are illuminated by the correspondence between him and his teacher Fronto. Although the main society literary figure of the age, Fronto was a dreary pedant whose blood ran rhetoric, but he must have been less lifeless than he now appears, for there is genuine feeling and real communication in the letters between him and both of the young men. It was to the credit of Marcus, who was intelligent as well as hardworking and serious-minded, that he grew impatient with the unending regime of advanced exercises in Greek and Latin declamation and eagerly embraced the Diatribai (Discourses) of a religious former slave, Epictetus, an important moral philosopher of the Stoic school. Henceforth, it was in philosophy that Marcus was to find his chief intellectual interest as well as his spiritual nourishment.


Meanwhile, there was work enough to do at the side of the untiring Antoninus, with learning the business of government and assuming public roles. Marcus was consul in 140, 145, and 161. In 145 he married his cousin, the emperor’s daughter Annia Galeria Faustina, and in 147 the imperium and tribunicia potestas, the main formal powers of emperorship, were conferred upon him; henceforth, he was a kind of junior coemperor, sharing the intimate counsels and crucial decisions of Antoninus. (His adoptive brother, nearly 10 years his junior, was brought into official prominence in due time.) On March 7, 161, at a time when the brothers were jointly consuls (for the third and the second time, respectively), their father died.

Roman emperor

The transition was smooth as far as Marcus was concerned; already possessing the essential constitutional powers, he stepped automatically into the role of full emperor (and his name henceforth was Imperator Caesar Marcus Aurelius Antoninus Augustus). At his own insistence, however, his adoptive brother was made coemperor with him (and bore henceforth the name Imperator Caesar Lucius Aurelius Verus Augustus). There is no evidence that Lucius Verus had much of a following, so a ruthless rival could have easily disposed of him, though to leave him in being as anything less than emperor might have created a focus for disaffection. It is most probable, however, that Marcus’s conscience impelled him to carry out loyally what he believed to have been the plan by which alone he himself had eventually reached the purple. For the first time in history, the Roman Empire had two joint emperors of formally equal constitutional status and powers, but, although the achievement of Lucius Verus has suffered by comparison with the paragon Marcus, it seems probable that the serious work of government was done throughout by Marcus and was the more arduous in that it was done during most of his reign in the midst of fighting frontier wars and combating the effects of plague and demoralization.

For constructive statesmanship or the initiation of original trends in civil policy, Marcus had little time or energy to spare. The field most congenial to him seems to have been the law. Numerous measures were promulgated and judicial decisions made, clearing away harshnesses and anomalies in the civil law, improving in detail the lot of the less-favoured—slaves, widows, minors—and giving recognition to claims of blood relationship in the field of succession (see inheritance). Marcus’s personal contribution, however, must not be overstated. The pattern of ameliorating legislation was inherited rather than novel, and the measures were refinements rather than radical changes in the structure of law or society; Marcus was not a great legislator, but he was a devoted practitioner of the role of ombudsman. Moreover, there was nothing specifically Stoic about this legal activity, and in one respect the age of Antoninus Pius and Marcus signalizes a retrogression in the relationship of law to society, for under them there either began or was made more explicit a distinction of classes in the criminal lawhonestiores and humiliores—with two separate scales of punishments for crime, harsher and more degrading for the humiliores at every point.

Marcus’s claim to statesmanship has come under critical attack in numerous other ways—for example, in the matter of Christian persecution. Although Marcus disliked the Christians, there was no systematic persecution of them during his reign. Their legal status remained as it had been under Trajan (reigned 98–117) and Hadrian: Christians were ipso facto punishable but not to be sought out. This incongruous position did little harm in times of general security and prosperity, but when either of these were threatened, the local population might denounce Christians, a governor might be forced to act, and the law, as the central authority saw it, must then run its course. The martyrdoms at Lyon in 177 were of this nature, and, though it appears that Christian blood flowed more profusely in the reign of Marcus the philosopher than it had before, he was not an initiator of persecution.

In 161 Syria was invaded by the Parthians, a major power to the east. The war that followed (162–166) was nominally under the command of Verus, though its successful conclusion, with the overrunning of Armenia and Mesopotamia, was the work of subordinate generals, notably Gaius Avidius Cassius. The returning armies brought back with them a plague, which raged throughout the empire for many years and—together with the German invasion—fostered a weakening of morale in minds accustomed to the stability and apparent immutability of Rome and its empire.

In 167 or 168 Marcus and Verus together set out on a punitive expedition across the Danube, and behind their backs a horde of German tribes invaded Italy in massive strength and besieged Aquileia, on the crossroads at the head of the Adriatic. The military precariousness of the empire and the inflexibility of its financial structure in the face of emergencies now stood revealed; desperate measures were adopted to fill the depleted legions, and imperial property was auctioned to provide funds. Marcus and Verus fought the Germans off with success, but in 169 Verus died suddenly, and doubtless naturally, of a stroke. Three years of fighting were still needed, with Marcus in the thick of it, to restore the Danubian frontier, and three more years of campaigning in Bohemia were enough to bring the tribes beyond the Danube to peace, at least for a time.
