Caracalla was Roman emperor from 211 to 217 CE. Born Lucius Septimius Bassianus, son of Septimius Severus and Julia Domna, he became co-ruler with his father in 198 CE and sole ruler after the death of his father in 211 CE and of his brother Geta later that same year. In his Edict of 212 CE, the Antonine Constitution, he granted Roman citizenship to all free inhabitants of the empire. This worked well as propaganda but at the same time also increased tax revenue for the state. Following his father's advice, he sought the support of the Roman army above all, sharing hardship with his soldiers on campaign. His campaigns in the western part of the Roman Empire secured the frontiers and made him popular with the army, but his campaign against Parthia in the east was less successful. He was assassinated by his praetorian prefect, Macrinus (r. 217-218 CE).
Early Life
Caracalla was born Lucius Septimius Bassianus on 4 April 188 CE in Lugdunum (Lyon) where his father Septimius Severus (r. 193-211 CE) was serving as the governor of Gallia Lugdunensis during the last years of Emperor Commodus (r. 180-192 CE). When Caracalla was seven, his name was changed to Marcus Aurelius Antoninus. This was done because of the wish of his father, now emperor, to link the new Severan dynasty with the previous Antonine one. The name 'Caracalla' was considered a nickname and referred to a type of cloak that the emperor wore (the nickname was originally used pejoratively and was never an official name of the emperor). At the time his name was changed, Caracalla became the official heir of his father, and in 198 CE at the age of ten, he was designated co-ruler with Severus (albeit a very junior co-ruler!).
From an early age, Caracalla was constantly in conflict with his brother Geta who was only 11 months younger than he. At the age of 14, Caracalla was married to the daughter of Severus' close friend Plautianus, Fulvia Plautilla, but this arranged marriage was not a happy one, and Caracalla despised his new wife (Dio 77.3.1 states that she was a 'shameless creature'). While the marriage produced a single daughter, it came to an abrupt end when in 205 CE Plautianus was accused and convicted of treason and executed. Plautilla was exiled and later put to death upon Caracalla's accession (Dio 77.5.3).
In the year 208 CE, Septimius Severus, upon hearing of troubles in Britain, thought it a good opportunity to not only campaign there but to take both of his sons with him as they were living libertine lifestyles in the city of Rome. Campaigning, Severus thought, would give both boys exposure to the realities of rule, thus providing experience for them which they could use upon succeeding their father. While in Britain, Geta was supposedly put in charge of civil administration there, while Caracalla and his father campaigned in Scotland. Although Caracalla did acquire some valuable experience in military matters, he seems to have revealed an even darker side of his personality and, according to Dio, tried on at least one occasion to kill his father so that he could become emperor. Although it was unsuccessful, Severus admonished his son, leaving a sword within his son's reach challenging him to finish the job that he botched earlier (Dio 77.14.1-7). Caracalla backed down, but according to Herodian, he was constantly trying to convince Severus' doctors to hasten the dying emperor's demise (3.15.2). In any case, the emperor died at Eboracum (modern York) in February 211 CE. Severus' last advice to both Caracalla and Geta was to "Be good to each other, enrich the army, and damn the rest" (Dio 77.15.2).
Caracalla Becomes Emperor
In 211 CE Caracalla became emperor along with his younger brother Geta. The relationship between the two did not resemble the loving one of Marcus Aurelius and Lucius Verus 50 years earlier, and it seems that both brothers were constantly conspiring against each other so that one of them could become sole emperor. When the two did try to make decisions together, they constantly bickered, disagreeing on everything from political appointments to legal decisions. Indeed, according to Herodian, things got so bad between the two brothers that not only did they divide the imperial palace between themselves but also tried to convince each other's cooks to drop poison into the other's food, it was also proposed that the empire be divided up between the two into eastern and western parts. According to Herodian, it was only the intervention of the boys' mother, Julia Domna, that this plan was not realized.
Nevertheless, Caracalla resolved to be rid of his brother. Dio describes a failed attempt to assassinate his brother on the Saturnalia, after which Caracalla arranged a meeting with his brother and mother in the imperial apartments, ostensibly to reconcile. Instead, upon appearing in his brother's room with centurions, Caracalla had his men murder Geta who tried to hide in his mother's arms. Despite her shock and sorrow, Caracalla forbade his mother from even shedding tears over Geta. So by 212 CE, Caracalla was sole emperor, and according to Dio, his brother's murder was followed by a purge of Geta's followers totalling roughly 20,000 deaths, including that of the former Praetorian Prefect Cilo and the jurist Papinian. Caracalla, when explaining his actions to the Senate, asserted that he was defending himself from Geta and rejected the idea that the concept of two emperors ruling the Roman Empire could work, declaring that
...you must lay aside your differences of opinion in thought and in attitude and lead your lives in security, looking to one emperor alone. Jupiter, as he is himself sole ruler of the gods, thus gives to one ruler sole charge of mankind. (Herodian 4.5)
The Roman Senate could do nothing but tremble before his words. Geta was duly damned from memory (damnatio memoriae), and all references to him in public were erased; it was considered a crime to mention his name.
Caracalla & the Army in the West
While Caracalla did not take his father's advice in being good to his brother, he certainly took to heart that he needed to keep the Roman army happy. Indeed, Caracalla declared to his soldiers that,
I am one of you," he said, "and it is because of you alone that I care to live, in order that I may confer upon you many favours; for all the treasuries are yours." And he further said: "I pray to live with you, if possible, but if not, at any rate to die with you. For I do not fear death in any form, and it is my desire to end my days in warfare. There should a man die, or nowhere." (Dio 78.3.2).
He backed up his words with actions by raising annual army pay, according to Herodian, by 50%. In order to pay for this raise, Caracalla debased the Roman coinage from a silver content of from about 58 to 50 percent. Caracalla also created a new coin known as the antoninianus which was supposed to be worth 2 denarii to help pay for these army raises (although the actual silver content was only worth 1.5 denarii). There has been a great debate over the years as to whether debasement of the coinage directly led to inflation. The more traditionalist school argues that debasement caused price inflation which began in the Severan era. A more 'moderate' school states that the debasements of Severus and Caracalla did not cause inflation; however, because of the precedent set by the Severans to debase, this became a regular practice of successive emperors when they needed coin, and that consequently inflation set in during the reign of Gordian III (r. 238-244 CE).
A third school of thought states that there is no evidence that inflation occurred at all in the 3rd century CE as a result of debasement as the empire was not fully monetized, especially in the frontier areas, and this extra coinage was merely absorbed into these non-monetized areas. Indeed, as long as those using the money were willing to accept the face value of the coinage, there would not be debasement-caused inflation. When inflation did occur, it usually was as a result of whenever an emperor such as Aurelian or Diocletian tried to reform the currency which caused a temporary loss of confidence in the coinage and caused prices to fluctuate wildly in the short term. This debate has been continuous and shows no signs of being resolved any time soon.
Moreover, he attempted to portray himself as a fellow soldier while on campaign, sharing in the army's labours, personally carrying legionary standards and even grinding his own flour and baking his own bread, as all Roman soldiers did. These actions made him wildly popular with the army.
During this time, military activity in Britain began to wind down. As the campaign in Britain had stalled by the end of Severus' reign, Caracalla thought it necessary to engage in a face-saving maneuver and end the campaign there, but not before essentially creating a protectorate in southern Scotland to keep an eye on native activities. This essentially not only ensured his father's legacy as a propagator imperii on the island but also would justify Caracalla's adoption of the title Britannicus. Even so, the natives north of Hadrian's Wall and the 'protectorate' had probably by this time felt discretion to be the better part of valour as making trouble had only invited the Roman army into their lands. If this is the case, then the Severan campaigns in Scotland kept that area peaceful for the better part of a century. There is also a degree of debate over whether it was Severus or in fact Caracalla who was the one to split Britain into two provinces in order to prevent governors from having access to a large number of legions thus tempting them to make a bid for the imperial throne.
Instead, upon leaving Rome in 213 CE, Caracalla (who would spend the rest of his reign in the provinces) decided to campaign in Raetia and Upper Germany against the Alemanni. While it is not clear if these enemies were making trouble for the empire, Caracalla prepared for this campaign very thoroughly and it seems that this campaign may have been a pre-emptive strike or a chance for Caracalla to win military glory in his own right. It has been argued that the threat posed by the Alemanni during their existence as a federation was fairly minimal but nevertheless always been overstated by Roman emperors, who used this threat as an excuse to campaign against an enemy as a way of building up their military credentials. That is, the Rhine frontier and the wars against the Alemanni were a training ground where emperors could improve their military skills so that they knew how to fight when a more important campaign arose. In any case, the campaign may have provided a good opportunity for the maintenance of this frontier and there was no serious enemy activity here until two decades later, so the emperor may have had a legitimate claim to the title of Germanicus which he adopted after these campaigns. Southern writes that Caracalla's frontier policy in this region:
...seems to have been a combination of open warfare and demonstrations of strength, followed by an organisation of the frontiers themselves. He may have paid subsidies to the tribes after his campaigns, and in other cases he stirred up one tribe against another to keep them occupied and their attentions diverted from Roman territory (Southern 2001, 53).
The Constitutio Antoniniana
One of the most noteworthy (and debated) acts of Caracalla's reign is his Edict of 212 CE (the Constitutio Antoniniana) which awarded Roman citizenship to all free inhabitants of the empire. The motives for this action are many. Propagandistically, this edict allowed Caracalla to portray himself as a more egalitarian emperor who believed that all free people of the empire should be citizens, thus creating a stronger sense of Roman identity among them.
More practically, however, this edict meant that Caracalla could widen the base from which he could collect an increased inheritance tax. Indeed, Dio states that, as a result of the money he lavished on the army, a financial shortfall was created and the emperor needed money, thus necessitating this edict and the consequent cheapening of the citizenship. In discussing this edict, Dio described how Caracalla was able to create a larger tax base while at the same time raising taxes to 5 percent on the manumission of slaves and 10 percent on inheritances. Moreover, the propaganda of equality was illusory, as instead of a hierarchy of citizens and non-citizens in the empire, the edict created a new class division of upper and lower classes (honestiores and humiliores) in which honestiores had greater legal rights and privileges, while humiliores had less legal protection and were subject to harsher punishments.
Caracalla in the East
Caracalla idolized Alexander the Great and sought to emulate him. Consequently, he saw fit to campaign in the east as a way to accomplish such emulation. It is debatable whether or not such campaigns were necessary, as at this time Rome's major rival, the Parthian Empire, was involved in internal conflicts, and the Parthian royal house was fighting among itself. Caracalla saw this, however, as an excuse to mount a campaign to make gains at the expense of the Parthians. He returned to Rome after his activities in Germany, summoned Abgar, the King of Edessa, to the city and imprisoned him in the hopes of turning Edessa into a colony and use it as a base from which to launch an invasion of Parthia. He seems to have tried to have done the same with the king of Armenia but encountered resistance from that land's population.
When he arrived in the East in 215 CE, Caracalla had little reason to justify an invasion of Parthia, as that empire's king, Vologaeses V, made a point to avoid any action that could be construed as a provocation. Leaving preparations for a campaign against Parthia to his general Theocritus, Caracalla visited Alexandria, ostensibly to pay respects to Alexander the Great at his tomb. He was first welcomed by the Alexandrians, but when he found out they were making jokes about the reasons he gave for the murder of his brother Geta, flew into a rage and had a large segment of the population massacred.
Caracalla then campaigned in Media in 217 CE and was planning a further campaign when his treacherous and rash behaviour caught up with him. It seems that he made sport of ridiculing his Praetorian Prefect M. Opellius Macrinus, who had a great deal of experience in Roman law but next to none in military affairs. Macrinus began to resent this, but Caracalla began to fear the man, especially after hearing of a prophecy that Macrinus would become emperor. Caracalla then began to move against his prefect, but Macrinus got wind of this and, realizing he was in great danger, conspired to assassinate the emperor. This he did on the road to Carrhae when the emperor stopped his troops on the side of the road to relieve himself. Evidently, while Caracalla was in the midst of urinating, one of Macrinus' men fell upon him, ending the emperor's life. Caracalla was 29 years old when he died. When the bulk of the army had heard of his end, they were enraged at the murder of the emperor whom they loved. Indeed, Macrinus' inability to placate the soldiers helped to play a part in his own demise when his enemies offered Caracalla's cousin Elagabalus as emperor in 218 CE.
Conclusion
Caracalla was one of the most unattractive individuals ever to become emperor of Rome. He was cruel, capricious, murderous, wilfully uncouth, and was lacking in any sort of filial loyalty save for that of his mother Julia Domna, who died shortly after his assassination. Dio 79.23 states that Julia Domna, possibly suffering from breast cancer and despairing at the death of her son, took her own life. This is certainly the picture given to us by both Dio and Herodian. While some of the information in these accounts might be embellished, they nevertheless shed light on the increasing trend of emperors depending more on the army, believing they could act in any way they wanted towards the rest of the population provided they keep the soldiers happy.
This is not entirely the fault of Caracalla, as he was following the advice of his father and genuinely wanted to be seen as a soldier and conqueror in the vein of Alexander the Great rather than the 'philosopher king' that Marcus Aurelius (r. 161-180 CE) embodied. While his military policies in the western empire may have contributed to that region's security for several years, his eastern policy was self-destructive and unnecessary. Had Caracalla followed the formula of Augustus (r. 27 BCE - 14 CE) and maintained a balance between keeping both the army and the upper echelons of Roman society happy, he may have been more successful. In any case, the following decades, a period known as the Crisis of the Third Century, would witness many so-called barracks emperors who took the tact that Caracalla had and would overly depend on the support of the army for their regime at their own peril.
