After winning the civil war, Octavian Augustus formally preserved the republican institutions, but in fact took all the key magistracies under his personal control. He planned to pass them on to one of his close relatives, thereby laying the foundations of the monarchical principle.

One of Augustus's potential successors was his stepson Drusus the Elder – the brother of the future Emperor Tiberius, married to Antonia the Younger, who in turn was the daughter of Mark Antony and Augustus's sister Octavia. Drusus proved himself a talented military leader and administrator, but in 9 BC he died after falling from a horse.

His eldest son Germanicus inherited his father's best qualities. After Augustus finally chose Tiberius as his successor and adopted him, Tiberius, at the insistence of the princeps, adopted Germanicus, thus making his blood nephew his obvious heir.

From his marriage to Augustus's granddaughter Agrippina the Elder, Germanicus had nine children, but only six of them reached adulthood. The youngest surviving son, born in 12 AD, was named after Gaius Julius Caesar. Thus, the boy was simultaneously the great-grandson of Octavian Augustus and Mark Antony, as well as the grand-nephew of Tiberius.

Germanicus became famous for his successful military campaigns in Germany, in which his family accompanied him. Once, his mother dressed the youngest son in children's armor with soldier's boots (caligae), after which the affectionate legionaries began to call the son of their beloved commander "Caligula," meaning "Little Boot." Under this name, he would enter history.

Disturbing Childhood

The first serious shock for the boy came in 14 AD, when after Augustus's death, Tiberius became the new princeps. At that time, some legions in Germany mutinied with the aim of proclaiming Germanicus as emperor. However, he did not wish to quarrel with his blood uncle and adoptive father, so he refrained from fighting and sent his family away from the military camp. In the absence of a leader, the mutiny subsided on its own.

In 18 AD, Caligula's father was sent with his family as the commander-in-chief of the troops to the eastern provinces of the Roman Empire. In Egypt, the locals attempted to deify the Germanicus sent to them, but he, like a virtuous republican, refused deification during his lifetime. Nevertheless, Caligula saw firsthand how power was perceived in the East.

Soon in 19 AD, Germanicus suddenly fell ill and died in Antioch. For 7-year-old Caligula, this was not only a personal but also a political tragedy. His family found themselves in the whirlpool of court intrigues.

Dangerous Youth

Around Germanicus's widow Agrippina the Elder and their sons, an influential political group formed. The mother consistently promoted the candidacies of Nero, Drusus, and Caligula as legitimate heirs, using the growing unpopularity of the frugal emperor, who had abandoned state affairs and retired to the island of Capri. An ally of this "party" was also Livia – the widow of Augustus, mother of Tiberius and Drusus the Elder, grandmother of Germanicus, and therefore great-grandmother of Caligula.

The opposition to the "party of Germanicus" consisted of supporters of Drusus the Younger – the biological son of Tiberius. However, Drusus suddenly died in 23 AD, after which his widow Livilla began to promote their son Tiberius Gemellus as heir. An ally of this "party" was the ambitious prefect of the praetorian guard – Lucius Aelius Sejanus, who concentrated more and more power in his hands as the emperor withdrew from affairs.

In 29 AD, Livia died, after which Sejanus managed to obtain permission from Tiberius to arrest Agrippina and her elder sons. Only the young Caligula escaped repression, sheltered and protected by his grandmother Antonia the Younger – the daughter of Mark Antony and niece of Augustus, widow of Drusus the Elder, mother of Germanicus... and Livilla.

Antonia the Younger, as the daughter of Mark Antony – a famous lover of the East – created an atmosphere of an eastern court, supported by young eastern aristocrats sent to Rome as honorary hostages. In their company, Caligula once again appreciated how power was represented in the East.

In 31 AD, Tiberius, with the help of Antonia the Younger, exposed Sejanus's conspiracy, after which the all-powerful prefect of the praetorian guard was executed, and Livilla, accused of poisoning her husband Drusus the Younger, was sent to her mother's house, where, according to legend, Antonia starved her daughter.

The defeat of the "party of Drusus the Younger" did not mean the rehabilitation of the "party of Germanicus." Caligula's mother Agrippina the Elder and his elder brothers – Nero and Drusus – remained in custody, where they soon died of starvation.

Apparently, Tiberius decided to raise the heir "in his own image," and chose Caligula for this role, who was transferred to the emperor on Capri. Along with training in military affairs and state administration, he also learned the lifestyle of the old princeps in the form of orgies and drunkenness. Among other things, Caligula with "great pleasure danced and sang on stage", which seemed unthinkable for a noble Roman of the republican era.

Theoretically, Caligula's co-ruler was supposed to be Tiberius Gemellus – the son of Drusus the Younger and Livilla. Ideally, this would reconcile the "parties" of Germanicus and Drusus the Younger. However, the potential co-ruler was seven years younger, and Caligula acquired an influential ally in the person of the new prefect of the praetorian guard Quintus Macro, who even "offered" his own wife Ennia to the heir to strengthen the alliance.

In March 37 AD, 77-year-old Tiberius died. As the commander of the praetorian guard, Macro, in violation of the deceased's will regarding co-rulership, ensured the immediate transfer of power in favor of only one princeps – 25-year-old Caligula. 18-year-old Tiberius Gemellus was formally adopted by the new emperor and declared heir.

A Promising Beginning

Rome rejoiced, for the princeps was the son of the beloved Germanicus, whose family was considered the embodiment of old republican virtues. Suetonius eloquently conveys the public enthusiasm: "The people's joy was such that in the next three incomplete months, it is said, more than one hundred and sixty thousand sacrificial animals were slaughtered."

Augustus came to power as the victor in the civil war and the pacifier of the "restored republic." By the time Tiberius was proclaimed princeps, he was already a distinguished military leader and administrator. The merit of the young Caligula lay only in the fact that he was from the "right" dynasty – an interesting note in the history of the transition from republican orders to monarchical ones.

The frugal Tiberius left his heir a substantial treasury, and he began his reign with generous spending: each Roman citizen received 150 sesterces, lavish spectacles resumed, feasts, bread distributions, and large-scale construction.

Caligula normalized relations with the Senate. All trials from Tiberius's time regarding offenses against majesty were stopped, both surviving and deceased were rehabilitated, including the new emperor's mother and brothers. Caligula declared that from now on "his ear is closed to informers" and restored the practice of public reports for magistrates. In modern terms, a political "thaw" occurred in Rome.

However, already in the fall of 37 AD, Caligula fell ill. The nature of the illness remained unclear, but there were rumors of poisoning. Most Romans sincerely hoped for the recovery of the beloved princeps. And he did recover, but seemed to become a different person. "Until now, we spoke of a ruler, henceforth we must speak of a monster," described the sudden change Suetonius.

Disappointment

The princeps "celebrated" his recovery with sudden executions. The first to fall was the heir Gemellus, who, to be fair, would always remain a focal point for any opposition.

Caligula did not spare his former father-in-law either – the influential senator Marcus Junius Silanus, the father of his first wife, who died before he became emperor.

The turn also came to Macro, who, along with his wife, was forced to commit suicide by the emperor's order, fearing the emergence of a "second" Sejanus. To weaken the influence of the commander of the praetorian guard, Caligula restored the collegiality of this position, appointing two prefects at once, as was practiced before Tiberius.

The "thaw" in relations with the Senate ended. Suetonius and Cassius Dio convey the famous story of the horse Incitatus, whom Caligula intended to make consul. This story is often presented as evidence of madness and infantilism. However, it can also be interpreted as a demonstration of the new power hierarchy, in which the emperor, as an autocratic monarch, could do anything concerning the old republican institutions. Cassius claims that the princeps even threatened to make the horse consul as a complete humiliation of the senators. Thus, it is, of course, about despotism, but not madness.

Instead of the Senate, Caligula began to rely on the support of the equestrian order and the urban plebs. In 38 AD, the emperor took away the Senate's right to elect magistrates and transferred it to the popular assembly, although this practice lasted only two years, after which there was a rollback. The plebs were also bribed with "bread and circuses" – it was under Caligula that this classical formula came to life.

As if making up for all the years spent in fear under Tiberius, Caligula now demonstratively indulged in luxury, sharply contrasting with the behavior of previous princeps. To the indignation of the old republicans, the emperor replied: "One must live either as a modest man or as a Caesar!"

Such extravagant policies required colossal funds. Caligula abolished the tax farming system and introduced new taxes, both direct and indirect. The revived trials for offenses against majesty also became a tool for replenishing the budget through confiscations of property from disloyal citizens.

The emperor did not forget the impressions from the East and its natives. He gifted Roman provinces Judea, Commagene, Lesser Armenia, Pontus, and Thrace to his friends from Antonia the Younger's upbringing. To be fair, in the same years he annexed Mauretania and killed its last king.

Like the Hellenistic monarchs of the East, Caligula, contrary to all republican traditions, deified himself during his lifetime as the embodiment of the god Jupiter. For comparison, Caesar or Augustus were deified only after death, but not during their lifetime.

Thus, with his unwillingness to at least imitate traditional republican virtues and his ostentatious demonstration of eastern despotism, Caligula alienated the Roman elite.

In 39 AD, a conspiracy against the emperor matured, involving his friend, official heir, husband of his beloved but early deceased sister Drusilla, consul Marcus Aemilius Lepidus, commander of the Upper German legions Gnaeus Lentulus Gaetulicus, and also the emperor's two other sisters – Agrippina and Livilla. Learning of the conspiracy in time, Caligula personally went to the Rhine legions, where he exposed and executed Gaetulicus. Lepidus was also executed, and the emperor's sisters were sent into exile.

In 39 – 40 AD, the princeps dedicated himself to organizing campaigns against the Germans beyond the Rhine, trying to repeat his father's successes. Although the scale of the campaigns was modest, they indeed achieved local successes. Caligula also planned a full-scale invasion of Britain but abandoned it due to the unstable situation within the empire.

And there was much to fear. A new conspiracy followed the exposed one, which the emperor did not have time to uncover. The decisive role was now played by the military tribunes of the praetorian guard Cassius Chaerea and Cornelius Sabinus, with the support of senators.

On January 24, 41 AD, the emperor was leaving the theater, where the Palatine Games were taking place, with his fourth wife Caesonia and his only legitimate child, 11-month-old Julia Drusilla, named after his beloved deceased sister. The conspirators attacked and killed all three.

Immediately after the emperor's assassination, the senators attempted to restore republican rule, but found no support from the plebs, legions, or praetorians. As a result, the latter proclaimed Claudius – the son of Drusus the Elder and Antonia the Younger, brother of Germanicus, and therefore uncle of Caligula – as the new princeps.

Ancient authors – representatives of the elite layers of society, all condemned Caligula and portrayed him as almost a madman. Not a single apologetic work about the emperor or even mentions of such have survived to us.

At the same time, modern historiography tends to view Caligula with greater understanding of his motives. A childhood and youth full of conspiracies and intrigues, constant fear for his own life, the death of all his relatives clearly affected the character of the future emperor. Becoming princeps, he in an eccentric manner began to demonstrate his autocracy in the spirit of an eastern monarch, which the Roman elite could never forgive him. Only two centuries later would Diocletian finally overcome republican remnants and successfully implement the system of the dominate, in which the ruler would officially be called "lord and god."
