Claudius in the context of "Galba"

The founding of Rome was a prehistoric event or process later greatly embellished by Roman historians and poets. Archaeological evidence indicates that Rome developed from the gradual union of several hilltop villages during the Final Bronze Age or early Iron Age. Prehistoric habitation of the Italian Peninsula occurred by 48,000 years ago, with the area of Rome being settled by around 1600 BC. Some evidence on the Capitoline Hill possibly dates as early as c. 1700 BC and the nearby valley that later housed the Roman Forum had a developed necropolis by at least 1000 BC. The combination of the hilltop settlements into a single polity by the later 8th century BC was probably influenced by the trend for city-state formation emerging from ancient Greece.

Roman myth held that their city was founded by Romulus, son of the war god Mars and the Vestal virgin Rhea Silvia, fallen princess of Alba Longa and descendant of Aeneas of Troy. Exposed on the Tiber river, Romulus and his twin Remus were suckled by a she-wolf at the Lupercal before being raised by the shepherd Faustulus, taking revenge on their usurping great-uncle Amulius, and restoring Alba Longa to their grandfather Numitor. The brothers then decided to establish a new town but quarrelled over some details, ending with Remus's murder and the establishment of Rome on the Palatine Hill. The year of the supposed founding was variously computed by ancient historians, but the two dates seeming to be officially sanctioned were the Varronian chronology's 753 BC (used by Claudius's Secular Games and Hadrian's Romaea) and the adjacent year of 752 BC (used by the Fasti and the Secular Games of Antoninus Pius and Philip I). Despite known errors in Varro's calculations, it is the 753 BC date that continues to form the basis for most modern calculations of the AUC calendar era.

Lucius Annaeus Seneca the Younger (/ˈsɛnɪkə/ SEN-ik-ə; c. 4 BC – AD 65), usually known mononymously as Seneca, was a Stoic philosopher of Ancient Rome, a statesman, a dramatist, and in one work, a satirist, from the post-Augustan age of Latin literature.

Seneca was born in Colonia Patricia Corduba in Hispania, and was trained in rhetoric and philosophy in Rome. His father was Seneca the Elder, his elder brother was Lucius Junius Gallio Annaeanus, and his nephew was the poet Lucan. In AD 41, Seneca was exiled to the island of Corsica under emperor Claudius, but was allowed to return in 49 to become a tutor to Nero. When Nero became emperor in 54, Seneca became his advisor and, together with the praetorian prefect Sextus Afranius Burrus, provided competent government for the first five years of Nero's reign. Seneca's influence over Nero declined with time, and in 65 Seneca was executed by forced suicide for alleged complicity in the Pisonian conspiracy to assassinate Nero, of which he may have been innocent, although there is still no consensus agreement. His stoic and calm suicide has become the subject of numerous paintings.

Titus Livius (Latin: [ˈtɪtʊs ˈliːwiʊs]; 59 BC – AD 17), known in English as Livy (/ˈlɪvi/ LIV-ee), was a Roman historian. He wrote a monumental history of Rome and the Roman people, titled Ab Urbe Condita, ''From the Founding of the City'', covering the period from the earliest legends of Rome before the traditional founding in 753 BC through the reign of Augustus in Livy's own lifetime. He was on good terms with members of the Julio-Claudian dynasty and was a friend of Augustus. Livy encouraged Augustus’s young grandnephew, the future emperor Claudius, to take up the writing of history.

The Secular or Saecular Games (Ludi Saeculares) was an ancient Roman religious celebration involving sacrifices, theatrical performances, and public games (ludi). It was held irregularly in Rome for three days and nights to mark the ends of various eras (saecula) and to celebrate the beginning of the next. In particular, the Romans reckoned a saeculum as the longest possible length of human life, either 100 or 110 years in length; as such, it was used to mark various centennials, particularly anniversaries from the computed founding of Rome.

According to Roman mythology, the Secular Games began as the Tarentine Games (Ludi Tarentini) when a Sabine man called Valesius prayed for a cure for his children's illness and was supernaturally instructed to sacrifice on the Campus Martius to Dis Pater and Proserpina, deities of the underworld. Some ancient authors traced official celebrations of the Games as far back as 509 BC, but the only clearly attested celebrations under the Roman Republic took place in 249 and in the 140s BC. They involved sacrifices to the underworld gods over three consecutive nights. The Games were revived in 17 BC by Rome's first emperor Augustus, with the nocturnal sacrifices on the Campus Martius now transferred to the Moerae (fates), the Ilythiae (goddesses of childbirth), and Terra Mater ("Mother Earth"). The Games of 17 BC also introduced day-time sacrifices to Roman deities on the Capitoline and Palatine hills. Certain sacrifices were unusually specified to be performed by married women. Each sacrifice was followed by theatrical performances. Later emperors held celebrations in AD 88 and 204, after intervals of roughly 110 years. However, they were also held by Claudius in AD 47 to celebrate the 800th anniversary of Rome's foundation, which led to a second cycle of Games in 148 and 248. The Games were abandoned under later Christian emperors.

Publius Cornelius Tacitus, known simply as Tacitus (/ˈtæsɪtəs/ TAS-it-əs, Latin: [ˈtakɪtʊs]; c. AD 56 – c. 120), was a Roman historian and politician. Tacitus is widely regarded as one of the greatest Roman historians by modern scholars.

Tacitus's two major historical works, Annals (Latin: Annales) and the Histories (Latin: Historiae), originally formed a continuous narrative of the Roman Empire from the death of Augustus (14 AD) to the end of Domitian's reign (96 AD). The surviving portions of the Annals focus on the reigns of Tiberius, Claudius, Nero, and those who reigned in the Year of the Four Emperors (69 AD).

Roman Britain was the territory that became the Roman province of Britannia after the Roman conquest of Britain, consisting of a large part of the island of Great Britain. The occupation lasted from AD 43 to AD 410.

Britain was invaded by Julius Caesar in 55 and 54 BC as part of the Gallic Wars. According to Caesar, the Britons had been overrun or culturally assimilated by the Belgae during the British Iron Age and had been aiding Caesar's enemies. The Belgae were the only Celtic tribe to cross the sea into Britain, for to all other Celtic tribes this land was unknown. He received tribute, installed the Celtic king Mandubracius over the Trinovantes, and returned to Gaul. Planned invasions under Augustus were called off in 34, 27, and 25 BC. In 40 AD, Caligula assembled 200,000 men at the Channel on the continent, only to have them gather seashells (musculi) according to Suetonius, perhaps as a symbolic gesture to proclaim Caligula's victory over the sea. Three years later, Claudius directed four legions to invade Britain and restore the exiled king Verica over the Atrebates. The Romans defeated the Catuvellauni, and then organized their conquests as the province of Britain. By 47 AD, the Romans held the lands southeast of the Fosse Way. Control over Wales was delayed by reverses and the effects of Boudica's uprising, but the Romans expanded steadily northwards.

The Julio-Claudian dynasty comprised the first five Roman emperors: Augustus, Tiberius, Caligula, Claudius, and Nero.

This line of emperors ruled the Roman Empire, from its formation (under Augustus, in 27 BC) until the last of the line, Emperor Nero, committed suicide (in AD 68).

Sextus Afranius Burrus (born AD 1 in Vasio, Gallia Narbonensis; died AD 62) was a prefect of the Praetorian Guard and was, together with Seneca the Younger, an advisor to the Roman emperor Nero, making him a very powerful man in the early years of Nero's reign.

Agrippina the Younger chose him as Prefect in 51 to secure her son Nero's place as emperor after the death of Claudius. For the first eight years of Nero's rule, Burrus and Nero's former tutor Seneca helped maintain a stable government. Burrus acquiesced to Nero's murder of Agrippina the Younger but lost his influence over Nero anyway. He died in 62, some say from poison, though officially he died of throat cancer.
