During most of this periods, though not always, there where two senior emperors ruling in separate courts. This division became permanent after the death of Theodosius I in 395.

Gaius Julius Caesar Augustus, also known as Octavian, was the founder of the Roman Empire. He reigned as the first Roman emperor from 27 BC until his death in AD 14. The reign of Augustus initiated an imperial cult, as well as an era of imperial peace in which the Roman world was largely free of armed conflict. The Principate system of government was established during his reign and lasted until the Crisis of the Third Century.
Marcus Aurelius Severus Alexander, also known as Alexander Severus, was Roman emperor from 222 until 235. The last emperor from the Severan dynasty, he succeeded his slain cousin Elagabalus in 222, at the age of 13. Alexander himself was eventually assassinated, and his death marked the beginning of the events of the Crisis of the Third Century, which included nearly fifty years of civil war, foreign invasion, and the collapse of the monetary economy.
Gaius Caesar Augustus Germanicus, better known by his nickname Caligula, was Roman emperor from AD 37 until his assassination in AD 41. He was the son of the Roman general Germanicus and Augustus' granddaughter Agrippina the Elder, members of the first ruling family of the Roman Empire. He was born two years before Tiberius was made emperor. Gaius accompanied his father, mother and siblings on campaign in Germania, at little more than four or five years old. He had been named after Gaius Julius Caesar, but his father's soldiers affectionately nicknamed him "Caligula".
Around the start of the Common Era, the family trees of the gens Julia and the gens Claudia became intertwined into the Julio-Claudian family tree as a result of marriages and adoptions.
The Severan dynasty, sometimes called the Septimian dynasty, was an Ancient Roman imperial dynasty that ruled the Roman Empire between 193 and 235, during the Roman imperial period. The dynasty was founded by the emperor Septimius Severus, who rose to power after the Year of the Five Emperors as the victor of the civil war of 193–197, and his wife, Julia Domna. After the short reigns and assassinations of their two sons, Caracalla and Geta, who succeeded their father in the government of the empire, Julia Domna's relatives themselves assumed power by raising Elagabalus and then Severus Alexander to the imperial office.
The Crisis of the Third Century, also known as the Military Anarchy or the Imperial Crisis (235–285), was a period in Roman history during which the Roman Empire had nearly collapsed under the combined pressure of repeated foreign invasions, civil wars and economic disintegration. At the height of the crisis, the Roman state had split into three distinct and competing polities.
The Holy Roman Emperor, originally and officially the Emperor of the Romans during the Middle Ages, and also known as the Roman-German Emperor since the early modern period, was the ruler and head of state of the Holy Roman Empire. The title was held in conjunction with the title of king of Italy from the 8th to the 16th century, and, almost without interruption, with the title of king of Germany throughout the 12th to 18th centuries.
The following outline is provided as an overview of and topical guide to ancient Rome:
Publius Septimius Geta was Roman emperor with his father Septimius Severus and older brother Caracalla from 209 to 211. Severus died in February 211 and intended for his sons to rule together, but they proved incapable of sharing power, culminating with the murder of Geta in December of that year.
The Roman emperor was the ruler and monarchical head of state of the Roman Empire, starting with the granting of the title augustus to Octavian in 27 BC. The term "emperor" is a modern convention, and did not exist as such during the Empire. Often when a given Roman is described as becoming emperor in English, it reflects his taking of the title augustus and later basileus. Another title used was imperator, originally a military honorific, and caesar, originally a surname. Early emperors also used the title princeps alongside other Republican titles, notably consul and pontifex maximus.
A regnal name, regnant name, or reign name is the name used by monarchs and popes during their reigns and subsequently, historically. Since ancient times, some monarchs have chosen to use a different name from their original name when they accede to the monarchy.
In modern historiography, ancient Rome encompasses the founding of the Italian city of Rome in the 8th century BC, the Roman Kingdom, Roman Republic, Roman Empire, and the collapse of the Western Roman Empire in the 5th century AD.
The Flavian dynasty, lasting from AD 69 to 96, 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 AD 69, 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 Principate was the form of imperial government of the Roman Empire from the beginning of the reign of Augustus in 27 BC to the end of the Crisis of the Third Century in AD 284, after which it evolved into the Dominate. The principate was characterised by the reign of a single emperor (princeps) and an effort on the part of the early emperors, at least, to preserve the illusion of the formal continuance, in some aspects, of the Roman Republic.
The Leonid dynasty or Thracian dynasty produced six Roman emperors during Late Antiquity, reigning over the Roman Empire from 457 to 518. The dynasty's patriarch was Leo I, who was made Roman emperor in 457. Leo's daughter Ariadne became empress and mother to an emperor, and her two husbands were themselves each made emperor in turn. Another relative whose name does not survive of Leo I or his wife Verina married the future augustus Julius Nepos, the last emperor in the western Roman Empire. The dynasty of Leo succeeded the preceding Valentinianic dynasty and Theodosian dynasty whose family trees were conjoined and ruled concurrently. Besides Julius Nepos, who administered no more than a rump state the Roman province of Dalmatia in the western empire during the fall of the west, the dynasty's emperors governed the eastern empire.
Archelaus was a Roman client prince and the last king of Cappadocia. He was also husband of Pythodorida, Queen regnant of Pontus.
The history of the Roman Empire covers the history of ancient Rome from the fall of the Roman Republic in 27 BC until the abdication of Romulus Augustulus in AD 476 in the West, and the Fall of Constantinople in the East in AD 1453. Ancient Rome became a territorial empire while still a republic, but was then ruled by Roman emperors beginning with Augustus, becoming the Roman Empire following the death of the last republican dictator, the first emperor's adoptive father Julius Caesar.
Nerva was a Roman emperor from 96 to 98. Nerva became emperor when aged almost 66, after a lifetime of imperial service under Nero and the succeeding rulers of the Flavian dynasty. Under Nero, he was a member of the imperial entourage and played a vital part in exposing the Pisonian conspiracy of 65. Later, as a loyalist to the Flavians, he attained consulships in 71 and 90 during the reigns of Vespasian and Domitian, respectively. On 19 September 96, Domitian was assassinated in a palace conspiracy involving members of the Praetorian Guard and several of his freedmen. On the same day, Nerva was declared emperor by the Roman Senate. As the new ruler of the Roman Empire, he vowed to restore liberties which had been curtailed during the autocratic government of Domitian.
The Eastern Roman Empire was ruled by the Theodosian dynasty from 379, the accession of Theodosius I, to 457, the death of Marcian. The rule of the Theodosian dynasty saw the final East-West division of the Roman Empire, between Arcadius and Honorius in 395. Whilst divisions of the Roman Empire had occurred before, the Empire would never again be fully reunited. The reign of the sons of Theodosius I contributed heavily to the crisis that under the fifth century eventually resulted in the complete collapse of western Roman court.
