Roman Imperial Era

from Wikipedia, the free encyclopedia
The greatest extent of the Roman Empire when the Emperor Trajan died in 117 AD. However, the provinces of Armenia , Assyria and Mesopotamia were only under Roman control for a few years.

The Roman empire (27 v. Chr. To 284 n. Chr.) Forms an epoch portion of the classical period , between the determined expansion and adaptation crises late Roman Republic and the late antiquity in which the Mediterranean a transformation process went through and Westrom went down .

Of Augustus outgoing reorganization of the state that the Prinzipat established, forming the start of the undisputed imperial epoch. Their end, however, can be dated differently with plausible reasons. The conventional epoch boundary is the deposition of the last Western Roman emperor Romulus Augustulus in the year 476, but recent research sees this date less and less as a real turning point (see end of antiquity ).

There is much to suggest that the change in the system of rule under Diocletian and the turn of Constantine the Great to Christianity, i.e. the years around 300, should be viewed as the end of the “classical” Roman Empire, as a number of fundamental changes took place at that time. For this reason, ancient historians today normally only understand the “imperial era” to be the era of the principate between 27 BC. And the end of the imperial crisis of the 3rd century AD 284. The present article is based on these epoch boundaries. Although there were still Roman emperors after 284 (in the west until 476 and in the eastern empire long afterwards), they ruled in a strongly changed environment.

Augustus and the Julio-Claudian dynasty

In the last 100 years of its existence, since the Gracchi attempts to reform, the Roman Republic has found itself in a phase of permanent civil war. Octavian, who was later called Augustus and was both great-nephew and adopted son of Gaius Julius Caesar , had first overcome Caesar's murderer in the power struggle following Caesar's murder and then his former colleague in the triumvirate , Mark Antony , who allegedly came from Egypt together with Cleopatra to establish a Hellenistic kingdom threatened at Actium 31 BC. Defeated BC. Augustus then laid down in January 27 BC He allegedly settled his autocracy, which he had achieved during the civil war, but had the authority of a tribune and commander-in-chief over the legions of the border provinces and periodically renewed what was the future formal basis of the empire (see principate ). This enabled him to legalize his power.

Propagandistically, he legitimized his claim to power through public and private building projects, donations to the plebs , the involvement of his person in the beginning cult and glorification of the inner peace achieved by the end of the civil wars in architecture (Ara pacis) and poetry, which experienced its classic heyday ( Virgil , Horace , Ovid ). Augustus had attracted the Senate, which had been greatly changed by civil wars and proscriptions, and later also by restructuring due to the censorship office, to his side through favors: the nobility was largely disempowered, but retained its prominent social position. By exhausting the constitutional leeway, Augustus was the first citizen of Rome (princeps) to gain permanent sole rule and thereby avoided the mistake of his predecessors of being suspected of restoring the hated kingship or of establishing a tyranny. In his report of deeds ( Res Gestae Divi Augusti ) Augustus calls himself superior in terms of reputation ( auctoritas ), but on the same level as his colleagues in terms of authority. In view of the princeps' special powers and power , this was a lie, but this fiction formed the ideological basis of the Roman monarchy for 300 years.

The city of Rome was redesigned architecturally and administratively in accordance with its political importance, such as through mansions, temple maintenance, games , baths as well as the establishment of a fire brigade and an urban guard entrusted with police-like tasks, whose commander-in-chief assumed a kind of imperial deputy position. In the social field, Augustus tried largely unsuccessfully to solve the decline in membership of the old noble patrician families through stricter marriage laws. Under Augustus, the empire was also expanded through the formal provincialization of Egypt and conquests in the Alpine region, northern Spain and the Balkans. The expansion into Germanic areas was completed soon after the defeat of Varus in 9; the areas between the Rhine and Elbe were not provincialized, but only indirectly controlled by the Romans.

His stepson and later adoptive son Tiberius (14-37 AD), a son of his wife Livia who was brought into the marriage, probably initially excluded Augustus from the line of succession (although the empire was formally never hereditary) because he denied him important offices . Augustus would have preferred a blood-related successor. Tiberius finally went into temporary exile in Rhodes in order not to be eliminated. Only after the death of Augustus' nephew Marcellus, General Agrippa , who was temporarily designated as heir, and his two grandsons Gaius and Lucius , Augustus appointed Tiberius as his successor. Tiberius tried to dispel possible doubts about his legitimacy by demonstratively hesitating when accepting the honors associated with the principate in the Senate. Nevertheless, the relationship between the emperor and the senate was disturbed, so that the senatorial historiography describes Tiberius as a tyrant. His cruel character traits are said to have emerged during his late reign, which were marked by the alleged high treason of the Praetorian prefect Lucius Aelius Seianus and the subsequent trials; Modern research has largely corrected this negative picture.

The historians paint an even more negative picture of the third emperor Caligula (37-41), on whom great hopes rested after Tiberius' death, but who, possibly because of his demonstrative turn to oriental kingship, became extinct after his murder and in the Historiography is portrayed as a mentally disturbed sadist. The apparently pathological actions of Caligula, who allegedly also wanted to raise his favorite horse Incitatus to the rank of senator, are often understood in modern research as humiliation rituals for the emperor who strives for absolutism.

Claudius (41-54) was initially passed over in favor of Caligula because of visible physical handicaps, but was the only legitimate candidate after the Senate revolt that led to the tyrant's assassination. Historiography portrays him as an introverted regent, hardly capable of his high office, who indulged himself in intellectual interests. In modern research, his government is rated as rather successful, mainly because he stabilized the borders and brought the expansion to a conclusion. Art historical research emphasizes the one-sidedness of the traditional image.

Similar to Caligula, Nero (54–68), who had been intrigued to succeed him by his ambitious mother Agrippina , was initially regarded as a figure of hope. In the first five years of his reign, which were recognized in contemporary literature with the Augustan term of the golden age, the young Nero was under the influence of his educator, the philosopher Seneca . Nero is portrayed in historiography as a tyrant and passionate actor who killed his mother. After the ensuing Pisonian conspiracy, Seneca, Lucan and Petronius , among others, had to commit suicide . Nero, in turn, was forced to commit suicide by the Senate, which had declared him an enemy of the state. He succumbed to senatorial condemnation, so that the historian Tacitus rumored to be the originator of the great fire in Rome, which he used to build his palace complexes. Due to the subsequent persecution of Christians , in which Paul allegedly also died, his tradition in Christian times was further discredited. His reign was also rated negatively by ancient historical research, for example, regarding the relationship to the senatorial upper class and the neglect of the army.

Nero's hostility to the two groups that legitimized rule, the Senate and the Army, led to the delegitimation of the Julio-Claudian family and into the civil war. The important role of the army became evident in the year of the Four Emperors , in which the generals Galba , Otho and Vitellius replaced each other as brief rulers and from which Vespasian finally emerged as the victor. His dynasty is called the Flavians after his family name.

The Flavians and the adoptive emperors

Vespasian (69–79) is portrayed in historiography as the complete opposite of Nero: he was down-to-earth, humorous and was considered a just ruler. During his reign, the uprising in Judea that had broken out under Nero in the year 70 was bloodily crushed. Vespasian also cracked down on the Germans , secured the borders on the Rhine and in the east against the Parthians , reorganized the army and restructured the finances. And although he maintained good relations with the Senate , he drew more and more powers to himself, but without tearing down the facade of the "republican order". The lack of legitimation of the Flavians due to their origin should be established through public buildings such as the Colosseum and the Arch of Titus. The surviving half of his inaugural law ( Lex de imperio Vespasiani ), which was probably given in a similar form to its predecessors, can be interpreted in its so-called discretionary clause as a transfer of absolute power, but the difficult text is also interpreted differently.

After his death, his sons Titus (79–81) and Domitian (81–96) ruled successfully overall. Titus' reign was overshadowed by the eruption of Mount Vesuvius and the outbreak of an epidemic. However, his quick relief efforts and generosity ensured that his name was fondly remembered. 81 Titus died, and his ambitious and sometimes cruel brother Domitian ascended the throne. Rumors arose that he had poisoned Titus, but these are completely unproven; In any case, the sources paint a gloomy picture of him, but one that is strongly tendentious. Domitian followed up on his father's policy on Germania and undertook several successful campaigns. Although popular with the army and the people, resistance arose at the court due to some cruel acts and his autocratic style of government (he allowed himself to be dubbed dominus et deus, “Lord and God”), which finally led to his assassination in 96. Persecution of Christians, which he was often accused of in older accounts, was of a regional nature and by no means systematic.

With Domitian one often lets the Early Imperial Era end and the High Imperial Era begin. The so-called adoptive emperors followed , who supposedly “chose the best” - which of course took into account the fact that they had no sons. Nerva (96–98), a generally weak and aged Princeps, chose - probably under duress - the dynamic Trajan (98–117) as his successor. This was the first emperor to come from the provinces, namely from Hispania . Trajan, who tried to clearly differentiate himself from Domitian, although he had served the Flavians loyally and in fact tied in with them in many ways, subjugated Dacia and at times also large parts of the Parthian Empire in protracted and sometimes bitter battles. The empire had reached its greatest expansion in the year 117 (from Scotland to the Sahara, from Spain and the Danube region to today's Iraq). However, a Jewish revolt broke out in the rear of the Romans as early as 115 , and the Parthians went on the offensive; then 117 Trajan died quite unexpectedly. His successor Hadrian (117-138), who allegedly had been determined by Trajan on his deathbed as his successor, saw the resources of Rome clearly overstretched and therefore gave up the threatened conquests in the east (withdrawal of the border to the Euphrates ). Hadrian had serious conflicts with the Senate, as several senators had been murdered after he came to power. But under his rule a certain cultural flowering developed, supported by Hadrian's philhellenism, which even the heavy Jewish uprising 132–135 could not diminish.

Denarius of Marcus Aurelius

Hadrian's defensive policy was continued by his successor Antoninus Pius (138-161), whose reign was remembered as a time of peace. This rest ended under Marcus Aurelius (161-180), who had Lucius Verus as co-ruler until his death in 169, although he was superior to him in auctoritas . Marcus Aurelius is traditionally called the "philosopher on the imperial throne" because of his inclination towards philosophy - he was a stoic . He felt compelled to wage several wars: In the east there were heavy defensive battles against the Parthians between 161 and 166, which were finally defeated. In addition, a wave of epidemics occurred in 165/166 (so-called Antonine plague ); the plague was brought into the empire by the Roman troops returning from the east and was to affect the empire severely. Under Marcus Aurelius, the empire also experienced the pre-emigration of peoples , the effects of which were among the causes of its later demise: There were two wars against the Marcomanni , Quadi and Sarmatians on the central Danube ( Marcomann wars : 167–175 and 178–180) . In these defensive battles the Roman troops only succeeded with difficulty in throwing back the invaders, but the emperor was finally able to launch a counter-offensive. In the middle of the campaign, Marcus Aurelius died in Vindobona . His decision to make his biological son Commodus (180–192) his successor put an end to the era of the adoptive empire.

The Severians and the Imperial Crisis of the 3rd Century

Commodus, who fell victim to a conspiracy at the end of 192, is attributed to appearances as a gladiator and pathological traits, following Nero's passionate acting, although the tradition from the Historia Augusta is strongly tendentious. His death heralded another troubled time, because the army's increasingly power to legitimize rule led into the second year of the Four Emperors, in which Septimius Severus (193-211), from the province of Africa , prevailed. He stabilized the boundaries and internal order of Rome and founded the dynasty of the Severi . His son and successor Caracalla (211-217), who had his brother and co-emperor Geta murdered without further ado, issued the Constitutio Antoniniana in 212 , which brought citizenship (and tax liability) to all free residents of the empire. The fighting on the Rhine against the Teutons, especially the Alamanni , and in the east against the Parthian Empire intensified soon afterwards. Caracalla was murdered in 217 while a Parthian campaign had begun. He was followed for a short time by Macrinus (who had been involved in the assassination of Caracalla and made peace with the Parthians) and Elagabal , before the last Severus ascended the throne with Severus Alexander (222-235); overall, he turned out to be a rather weak emperor. He waged war against the Sassanids and Alemanni in the east ; In 235 he was murdered by insurgent soldiers in Mainz. After his death, the troubled times of the soldier emperors followed .

The time of the soldier emperors was marked by the rapid change of rulers, but also by constant internal and external pressure ( imperial crisis of the 3rd century ), which sometimes led to economic problems. The “system of acceptance” that had been tried and tested since the early imperial era, according to which the legitimacy of every princeps was based on the consent of the army, senate and people of Rome, reached its limits; the army on the frontiers now became the only decisive political factor. Inside, the Gallic Empire split off from Rome in 260 . In the north the pressure from neighboring peoples persisted, in the east the New Persian Sassanid Empire became a dangerous enemy . Emperor Valerian was even captured in 260, which meant the low point of Rome's prestige in the east; meanwhile, Palmyra took control of large parts of Asia Minor and Egypt . These centrifugal effects could only be eliminated after some effort. Above all, Emperor Aurelian (270–275) was able to stabilize the situation again and regain lost territories.

Emperor Carus (282–283) remained victorious against the Sassanids. His death (or that of his son Carinus ) ended the age of the soldier emperors , because his successor Diocletian carried out extensive reforms, including the division of the imperial rule into the rule of four ( tetrarchy ), with which the beginning of late antiquity is generally associated.

The preceding epochs are mostly divided into the Early ( Augustus to Domitian ) and High ( Nerva to Carinus ) Imperial Era. If one includes the late Imperial Era (or late antiquity), the common dates for the end of the Imperial Era, as opposed to the Middle Ages and the Byzantine Era, are the year 476 (deposition of the Western Roman Emperor Romulus Augustulus ), 565 (death of the Eastern Roman Emperor Justinian I. ) or the early 7th century ( Islamic expansion ). In terms of cultural history, the closure of the Platonic Academy by Justinian I in 529 and the founding of the first Benedictine monastery in Monte Cassino in the same year are often mentioned as a striking date in the transition from antiquity to the Middle Ages.
