Galba in the context of Nero

The Parallel Lives (Ancient Greek: Βίοι Παράλληλοι, Bíoi Parállēloi; Latin: Vītae Parallēlae) is a series of 48 biographies of famous men written in Greek by the Greco-Roman philosopher, historian, and Apollonian priest Plutarch, probably at the beginning of the second century. The lives are arranged in pairs to illuminate their common moral virtues or failings.

The surviving Parallel Lives comprises 23 pairs of biographies, each pair consisting of one Greek and one Roman of similar destiny, such as Alexander the Great and Julius Caesar, or Demosthenes and Cicero. There are also four singular Lives, recounting the stories of Artaxerxes, Aratus, Galba, and Otho. Traces of other biographies point to an additional twelve single Lives that are now missing.

Otho (/ˈoʊθoʊ/ OH-tho; born Marcus Salvius Otho; 28 April 32 – 16 April 69) was Roman emperor, ruling for three months from 15 January to 16 April 69. He was the second emperor of the Year of the Four Emperors.

A member of a noble Etruscan family, Otho was initially a friend and courtier of the young emperor Nero until he was effectively banished to the governorship of the remote province of Lusitania in 58 following his wife Poppaea Sabina's affair with Nero. After a period of moderate rule in the province, he allied himself with Galba, the governor of neighbouring Hispania Tarraconensis, during the revolts of 68. He accompanied Galba on his march to Rome, but revolted and murdered Galba at the start of the next year.

The 1st century was the century spanning AD 1 (represented by the Roman numeral I) through AD 100 (C) according to the Julian calendar. It is often written as the 1st century AD or 1st century CE to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The Roman Empire, Han China and the Parthian Persia were the most powerful and hegemonic states.

During this century, the Roman Empire (ruled by the Julio-Claudian and Flavian dynasties) continued to be in a period of relative stability known as Pax Romana, withstanding a financial crisis in 33 and a civil war in 69. In Europe, Rome expanded into Britain and fought wars in Germania and Dacia. In Africa, Rome was challenged by Tacfarinas, who led his own Musulamii tribe and a loose and changing coalition of other Berber tribes before being defeated in 24. In West Asia, Rome defeated a Jewish rebellion (66–73) and fought a war with Parthia from 58–63, though the latter conflict was inconclusive. In East Asia, the Chinese Western Han dynasty was overthrown and replaced by the Xin dynasty in 9, which in turn faced its own rebel movements (namely the Red Eyebrows and Lulin), and was replaced by the Eastern Han dynasty in 25. The Eastern Han dynasty then faced and quelled a rebellion by the Trưng sisters (40–43). In 58, the Eastern Han dynasty entered a golden age with the Rule of Ming and Zhang, who were generally regarded as able administrators who cared about the common welfare of the people and who promoted officials with integrity. On its northern frontier, the Chinese dynasties waged intermittent war with the Xiongnu before emerging victorious in 91. The states of Funan and Xianbei were also established in this century.

Johannine literature is a modern collective term for five New Testament writings that early Christian tradition linked in various ways with John the Apostle or a related circle of teachers: the Gospel of John, the three Johannine epistles (1 John, 2 John, and 3 John), and the Book of Revelation. The designation identifies a literary family with shared vocabulary and theology without implying single authorship, and it reflects how ancient readers grouped the texts while acknowledging distinct voices within them.

Current scholarship usually dates the Gospel and Letters to the final decades of the first century, often AD 90–110; some pursue earlier signs and editions, while recent scholarship increasingly views the gospel as a literary unity by a single author. Revelation is most often dated within the reign of Domitian (AD 81–96) because of its address to seven assemblies in Roman Asia and its critique of imperial cult imagery, though a minority advocates an earlier context in the late 60s under Nero or Galba.

The Year of the Four Emperors, AD 69, was the first civil war of the Roman Empire, during which four emperors ruled in succession, Galba, Otho, Vitellius, and Vespasian. It is considered an important interval, marking the change from the Julio-Claudians, the first imperial dynasty, to the Flavian dynasty. There were several rebellions and claimants, with shifting allegiances and turmoil in Rome and the provinces.

In 68, Vindex, legate of Gallia Lugdunensis, revolted against Nero and encouraged Galba, governor of Hispania, to claim the Empire. The latter was proclaimed emperor by his legion in early April. He was notably supported by Otho, legate of Lusitania. Soon after, the legate of a legion in Africa, Clodius Macer, also rebelled against Nero. Vindex was defeated by the Rhine legions at the Battle of Vesontio, but they too rebelled against Nero. On 9 June 68, Nero took his own life after being declared a public enemy by the Senate, which made Galba the new emperor. Galba was unable to establish his authority over the Empire, as several of his supporters were disappointed by his lack of gratitude. He especially adopted Piso Licinianus as heir (Galba was childless and elderly), instead of Otho, who, it had widely been assumed, would be chosen. Angered by this disgrace, Otho murdered Galba on 15 January with the help of the Praetorian Guard, and became emperor instead. Unlike Galba, he rapidly earned considerable popularity, notably by bestowing favours and emulating Nero's successful early years.

The Flavian dynasty, lasting from 69 to 96 CE, was the second dynastic line of emperors to rule the Roman Empire following the Julio-Claudians, encompassing the reigns of Vespasian and his two sons, Titus and Domitian. The Flavians rose to power during the civil war of 69 CE, known as the Year of the Four Emperors; after Galba and Otho died in quick succession, Vitellius became emperor in mid 69. His claim to the throne was quickly challenged by legions stationed in the eastern provinces, who declared their commander Vespasian emperor in his place. The Second Battle of Bedriacum tilted the balance decisively in favor of the Flavian forces, who entered Rome on 20 December, and the following day, the Roman Senate officially declared Vespasian emperor, thus commencing the Flavian dynasty. Although the dynasty proved to be short-lived, several significant historic, economic and military events took place during their reign.

The reign of Titus was struck by multiple natural disasters, the most severe of which was the eruption of Mount Vesuvius in 79 CE, which saw the surrounding cities of Pompeii and Herculaneum be completely buried under ash and lava. One year later, Rome was struck by fire and a plague. On the military front, the Flavian dynasty witnessed the siege and destruction of Jerusalem by Titus in 70 CE, following the failed Jewish rebellion of 66. Substantial conquests were made in Great Britain under the command of Gnaeus Julius Agricola between 77 and 83 CE, while Domitian was unable to procure a decisive victory against King Decebalus in the war against the Dacians. In addition, the Empire strengthened its border defenses by expanding the fortifications along the Limes Germanicus.

De vita Caesarum (Latin; lit. "On the Life of the Caesars"), commonly known as The Twelve Caesars or The Lives of the Twelve Caesars, is a set of twelve biographies of Julius Caesar and the first 11 emperors of the Roman Empire during the Principate. The subjects are Julius Caesar, Augustus, Tiberius, Caligula, Claudius, Nero, Galba, Otho, Vitellius, Vespasian, Titus, Domitian.

The Twelve Caesars was written in 121 CE by Gaius Suetonius Tranquillus (called "Suetonius" by scholars) while he served as a personal secretary to the emperor Hadrian. Suetonius dedicated the work to his friend, Gaius Septicius Clarus, a praetorian prefect.

Libertas (Latin for 'liberty' or 'freedom', pronounced [liːˈbɛrt̪aːs̠]) is the Roman goddess and personification of liberty. She became a politicised figure in the late republic. She sometimes also appeared on coins from the imperial period, such as Galba's "Freedom of the People" coins during his short reign after the death of Nero. She is usually portrayed with two accoutrements: the spear; and pileus, a cap commonly worn by freed slaves, which she holds out in her right hand rather than wears on her head.

The Greek equivalent of the goddess Libertas is Eleutheria, the personification of liberty. There are many post-classical depictions of liberty as a person which often retain some of the iconography of the Roman goddess.

Aulus Vitellius (/vɪˈtɛliəs/ vih-TELL-ee-əs; Latin: [ˈaːwlus wiˈtɛːlːijus]; 24 September 15 – 20 December 69) was Roman emperor for eight months, from 19 April to 20 December AD 69. Vitellius became emperor following the quick succession of the previous emperors Galba and Otho, in a year of civil war known as the Year of the Four Emperors. Vitellius added the honorific Germanicus to his name instead of Caesar upon his accession. Like his predecessor, Otho, Vitellius attempted to rally public support to his cause by honoring and imitating Nero who remained popular in the empire.

Originally from Campania, likely from Nuceria Alfaterna, he was born to the Vitellia gens, a relatively obscure family in ancient Rome. He was a noble companion of Tiberius' retirement on Capri and there befriended Caligula. He was elected consul in 48, and served as proconsular governor of Africa in either 60 or 61. In 68, he was chosen to command the army of Germania Inferior by emperor Galba. He was later proclaimed emperor in January by the armies of Germania Inferior and Superior, beginning a revolt against Galba. Galba was assassinated by Otho, and Vitellius then faced Otho in battle. He defeated Otho at the Battle of Bedriacum, and was recognized emperor by the Roman Senate.

AD 69 (LXIX) was a common year starting on Sunday of the Julian calendar. In the Roman Empire, it was known as the Year of the consulship of Galba and Vinius (or, less frequently, year 822 Ab urbe condita). The denomination AD 69 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Lucius Clodius Macer was a legatus of the Roman Empire in Africa during the reign of Nero. He revolted in May 68, cutting off the food supply of Rome, possibly at the instigation of Calvia Crispinilla. Although encouraged by Galba, Macer raised a legion Legio I Macriana liberatrix in addition to the Legio III Augusta that he already commanded, presumably raising suspicion that Macer also harbored imperial ambitions. In October 68, Galba had him killed by the procurator Trebonius Garutianus. Papirus, the centurion of Mucianus, was implicated in his assassination.

Macer produced denarii which are extremely rare today. Only about 85 have been found, of which only 20 bear his portrait. He uses the formulaic abbreviation S C (senatus consulto) on his denarii; this otherwise had only rarely appeared on Roman silver coins since about 40 BC. Scholars speculate that this, and his decision to portray himself without a laurel wreath or a diadem, as evidence that he portrayed his revolt as being against Nero, and not the senate.

The Battle of Vesontio was a conflict in 68 AD in which Lucius Verginius Rufus defeated Gaius Julius Vindex. Vindex had rebelled against the Emperor Nero and declared his allegiance to Galba. Verginius advanced against him and a battle between their two forces took place near Vesontio (modern Besançon). What occurred then is unclear, but, despite a meeting between Verginius and Vindex, the forces under Verginius seem to have decided on a battle without orders. Desire for plunder and the weakness of Verginius as a commander are possible explanations. Vindex was defeated in the resulting battle and subsequently committed suicide.

Lucius Calpurnius Piso Frugi Licinianus (38–69) was a Roman nobleman who lived in the 1st century. His adoption by the Roman emperor Galba on 10 January 69 AD precipitated their joint murder by Otho, who had expected to be adopted instead. Otho then became the second emperor of the Year of the Four Emperors.
