Query: Who was the last emperor of the Roman Empire?
Flavius Romulus Augustus (c. AD 460 – after AD 476; possibly still alive as late as AD 507),[3] known derisively and historiographically as Romulus Augustulus, was the Roman emperor who ruled the Western Roman Empire from 31 October 475 until 4 September 476. He is often described as the "last Western Roman emperor", though some historians consider this to be Julius Nepos. His deposition by Odoacer traditionally marks the end of the Roman Empire in the West, the end of Ancient Rome, and the beginning of the Middle Ages in Western Europe.
The nephew of the last Emperor, Constantine XI, Andreas Palaeologos had inherited the title of Roman Emperor. He lived in the Morea (Peloponnese) until its fall in 1460, then escaped to Rome where he lived under the protection of the Papal States for the remainder of his life. He styled himself "Imperator Constantinopolitanus" ("Emperor of Constantinople"), and sold his succession rights to both Charles VIII of France and the Catholic Monarchs. However, no one ever invoked the title after Andreas's death, thus he is considered to be the last titular Roman Emperor. Mehmed II and his successors continued to consider themselves heirs to the Roman Empire until the demise of the Ottoman Empire in the early 20th century. Meanwhile, the Danubian Principalities (whose rulers also considered themselves the heirs of the Eastern Roman Emperors) harboured Orthodox refugees, including some Byzantine nobles.
The Empire of Romania (), more commonly known in historiography as the Latin Empire or Latin Empire of Constantinople, and known to the Byzantines as the "Frankokratia" or the Latin Occupation, was a feudal Crusader state founded by the leaders of the Fourth Crusade on lands captured from the Eastern Roman (Byzantine) Empire. It was established after the capture of Constantinople in 1204 and lasted until 1261. The Latin Empire was intended to supplant the Byzantine Empire as the titular Roman Empire in the east, with a Western Roman Catholic emperor enthroned in place of the Eastern Orthodox Roman emperors.
The German Emperor ( ) was the official title of the head of state and hereditary ruler of the German Empire. A specifically chosen term, it was introduced with the 1 January 1871 constitution and lasted until the official abdication of Wilhelm II on 28 November 1918. The Holy Roman Emperor is sometimes also called "German Emperor" when the historical context is clear, as derived from the Holy Roman Empire's official name of "Holy Roman Empire of the German Nation" from 1512.
As an institution, the consulship survived the abdication of the last emperor of the West, and for a time consuls continued to be appointed, one representing the Eastern Roman Empire, and the other the Western, even as the Western Empire dissolved as a political entity. The last consuls appointed represented only the Eastern Empire, until finally the title became the sole province of the Emperor, who might or might not assume it upon taking office.
Gibbon took September 4, 476 as a convenient marker for the final dissolution of the Western Roman Empire, when Romulus Augustus, the last Emperor of the Western Roman Empire, was deposed by Odoacer, a Germanic chieftain. Some modern historians question the significance of the year 476 for its end. Julius Nepos, the Western emperor recognized by the Eastern Roman Empire, continued to rule in Dalmatia, until he was assassinated in 480. The Ostrogothic rulers of Italia considered themselves upholders of the direct line of Roman tradition, and the Eastern emperors considered themselves the sole rightful Roman rulers of a united empire. Roman cultural traditions continued throughout the territory of the Western Empire, and a recent school of interpretation argues that the great political changes can more accurately be described as a complex cultural transformation, rather than a fall.
The Western Roman Empire collapsed in the late 5th century. Romulus Augustulus is often considered to be the last emperor of the West after his forced abdication in 476, although Julius Nepos maintained a claim recognized by the Eastern Empire to the title until his death in 480. Following Nepos' death, the Eastern Emperor Zeno abolished the division of the position and proclaimed himself as the sole Emperor of a reunited Roman Empire. The Eastern imperial lineage continued to rule from Constantinople ("New Rome"); they continued to style themselves as Emperor of the Romans (later βασιλεύς Ῥωμαίων in Greek), but are often referred to in modern scholarship as Byzantine emperors. Constantine XI Palaiologos was the last Roman emperor in Constantinople, dying in the Fall of Constantinople to the Ottomans in 1453.
The authority of Julius Nepos as Emperor was accepted not only by Odoacer in Italy, but by the Eastern Empire and Syagrius in Gaul (who had not recognized Romulus Augustulus). Nepos was murdered by his own soldiers in 480, a plot some attribute to Odoacer or the previous, deposed emperor Glycerius, and the Eastern Emperor Zeno chose not to appoint a new western emperor. Zeno, recognizing that no true Roman control remained over the territories legally governed by the Western court, instead chose to abolish the juridical division of the position of Emperor and declared himself the sole emperor of the Roman Empire. Zeno became the first sole Roman emperor since the division after Theodosius I, 85 years prior, and the position would never again be divided. As such, the (eastern) Roman emperors after 480 are the successors of the western ones, albeit only in a juridical sense. These emperors would continue to rule the Roman Empire until the Fall of Constantinople in 1453, nearly a thousand years later. As 480 marks the end of the juridical division of the empire into two separate imperial courts, some historians refer to the death of Nepos and abolition of the Western Empire by Zeno as the end of the Western Roman Empire.
The Roman Empire, at its height (c. 117 CE), was the most extensive political and social structure in western civilization. By 285 CE the empire had grown too vast to be ruled from the central government at Rome and so was divided by Emperor Diocletian into a Western and an Eastern Empire. The Roman Empire began when Augustus Caesar became the first emperor of Rome (31 BCE) and ended, in the west, when the last Roman emperor, Romulus Augustulus, was deposed by the Germanic King Odoacer (476 CE). In the east, it continued as the Byzantine Empire until the death of Constantine XI and the fall of Constantinople to the Ottoman Turks in 1453 CE. The influence of the Roman Empire on western civilization was profound in its lasting contributions to virtually every aspect of western culture.
Theodosius was the last Emperor who ruled over the whole Empire. After his death in 395, he gave the two halves of the Empire to his two sons Arcadius and Honorius; Arcadius became ruler in the East, with his capital in Constantinople, and Honorius became ruler in the West, with his capital in Milan and later Ravenna. The Roman state would continue to have two different emperors with different seats of power throughout the 5th century, though the Eastern Romans considered themselves to be the only ones who were fully Roman. Latin was used in official writings as much as, if not more than, Greek and the two halves were nominally, culturally and historically, if not politically, the same state.
In 1804, Napoleon Bonaparte declared the First French Empire. In response to this, Emperor Francis II of the Habsburg dynasty declared his personal domain to be the Austrian Empire and became Francis I of Austria. Taking the colours of the banner of the Holy Roman Emperor, the flag of the Austrian Empire was black and gold. Francis II was the last Holy Roman Emperor, with Napoleon forcing the empire's dissolution in 1806. After this point, these colours continued to be used as the flag of Austria until 1918.
Diocletian divided the empire into four regions, each ruled by a separate emperor, the Tetrarchy. Confident that he fixed the disorders that were plaguing Rome, he abdicated along with his co-emperor, and the Tetrarchy soon collapsed. Order was eventually restored by Constantine the Great, who became the first emperor to convert to Christianity, and who established Constantinople as the new capital of the eastern empire. During the decades of the Constantinian and Valentinian dynasties, the empire was divided along an east–west axis, with dual power centres in Constantinople and Rome. The reign of Julian, who under the influence of his adviser Mardonius attempted to restore Classical Roman and Hellenistic religion, only briefly interrupted the succession of Christian emperors. Theodosius I, the last emperor to rule over both East and West, died in 395 AD after making Christianity the official religion of the empire.
The play is about the Roman Emperor Julian the Apostate. The play covers the years 351–363. Julian was the last non-Christian ruler of the Roman Empire. It was his desire to bring the empire back to its ancient Roman values. Another crucial and more sympathetic feature of Emperor Julian, is his disliking of his own dynasty, who, in the play at least, were claiming descent and authority for being Gallileans, making Jesus Christ their own, in terms of ethnicity.
The conversion of Constantine I transformed the relationship of the Christian churches with the Roman military even as it transformed the relationship of the churches with the Roman state. A strongly contrary idea, sometimes called "caesaropapism", identified the now Roman Catholic Empire with the Church militant. The Latin word "Christianitas" originally meant the body of all Christians conceived as a political body, or the territory of the globe occupied by Christians, something akin to the English word Christendom. Apocalyptic texts were reinterpreted. The idea of a Christian empire continued to play a powerful role in Western Europe even after the collapse of Roman rule there; the name of the Holy Roman Empire bears witness to its claims to sanctity as well as to universal rule. An apocryphal apocalypse of Pseudo-Methodius, written during the seventh century, depicts a saintly Last Roman Emperor who holds his earthly kingdom in anticipation of Christ's return. According to Pseudo-Methodius, the Last Emperor will wage war in the last days against God's enemies, including Gog and Magog and the Antichrist. 
Ten Roman emperors were born in the city and its envirions:The last emperor of the united Roman Empire, Theodosius I (378–95), became emperor in Sirmium. The usurpers Ingenuus and Regalianus also declared themselves emperors in this city (in 260) and many other Roman emperors spent some time in Sirmium including Marcus Aurelius who might have written parts of his famous work "Meditations" in the city.
Last Roman Emperor, Last World Emperor or Emperor of the Last Days is a figure of medieval European legend, which developed as an aspect of eschatology in the Catholic Church. The legend predicts that in the end times, a last emperor would appear on earth to reestablish the Holy Roman Empire and assume his function as biblical katechon who stalls the coming of the Antichrist. The legend first appears in the 7th-century apocalyptic text known as the "Apocalypse of Pseudo-Methodius"; that and the oracles of the Tiburtine Sibyl are its two most important sources. It developed over the centuries, becoming particularly prominent in the 15th century. The notion of Great Catholic Monarch is related to it, as is the notion of the Angelic Pope.

Roman expansion began long before the state was changed into an Empire and reached its zenith under emperor Trajan with the conquest of Mesopotamia and Armenia in AD 113. The period of the "Five Good Emperors" saw a successions of peaceful years and the Empire was prosperous. Each emperor of this period was adopted by his predecessor. The Nerva–Antonine dynasty was a dynasty of seven consecutive Roman Emperors who ruled over the Roman Empire from 96 to 192. These Emperors are Nerva, Trajan, Hadrian, Antoninus Pius, Marcus Aurelius, Lucius Verus, and Commodus.
The last two of the "Five Good Emperors" and Commodus are also called Antonines. After his accession, Nerva, who succeeded Domitian, set a new tone: he restored much confiscated property and involved the Roman Senate in his rule. Starting in 101, Trajan undertook two military campaigns against the gold rich Dacia, which he finally conquered in 106 (see Trajan's Dacian Wars). In 112, Trajan marched on Armenia and annexed it to the Roman Empire. Then he turned south into Parthia, taking several cities before declaring Mesopotamia a new province of the empire, and lamenting that he was too old to follow in the steps of Alexander the Great. During his rule, the Roman Empire expanded to its largest extent, and would never again advance so far to the east. Hadrian's reign was marked by a general lack of major military conflicts, but he had to defend the vast territories that Trajan had acquired.
Francis II (; 12 February 1768 – 2 March 1835) was the last Holy Roman Emperor, ruling from 1792 until 6 August 1806, when he dissolved the Holy Roman Empire of the German Nation after the decisive defeat at the hands of the First French Empire led by Napoleon at the Battle of Austerlitz. In 1804, he had founded the Austrian Empire and became Francis I, the first Emperor of Austria, ruling from 1804 to 1835, so later he was named the one and only "Doppelkaiser" (double emperor) in history.
For the two years between 1804 and 1806, Francis used the title and style "by the Grace of God elected Roman Emperor, ever Augustus, hereditary Emperor of Austria" and he was called the "Emperor of both the Holy Roman Empire and Austria". He was also Apostolic King of Hungary and Bohemia as Francis I. He also served as the first president of the German Confederation following its establishment in 1815.
Disunion in the Roman Empire further contributed to disunion in the Church. Emperor Diocletian divided the administration of the eastern and western portions of the empire in the early 4th century, though subsequent leaders (including Constantine) aspired to and sometimes gained control of both regions. Theodosius I, who established Christianity as the official religion of the Roman Empire, died in 395 and was the last emperor to rule over a united Roman Empire; following his death, the division into western and eastern halves, each under its own emperor, became permanent. By the end of the 5th century, the Western Roman Empire had been overrun by the Germanic tribes, while the Eastern Roman Empire (known also as the Byzantine Empire) continued to thrive. Thus, the political unity of the Roman Empire was the first to fall.
Charlemagne, crowned Roman Emperor in 800 AD, is sometimes considered as a forerunner of the Holy Roman Empire. Most historians today reject this view, arguing that the Holy Roman Empire had different antecedents and a different constitution, and the Holy Roman Emperor had a different status and role than Charlemagne and his successors. After the collapse of Charlemagne's empire, the Imperial crown was initially disputed among the Carolingian rulers of Western Francia (France) and Eastern Francia (Germany), with first the western king (Charles the Bald) and then the eastern (Charles the Fat) attaining the prize. However, after the death of Charles the Fat in 888, the empire broke asunder, never to be restored. According to Regino of Prüm, each part of the realm elected a "kinglet" from its own "bowels". After the death of Charles the Fat, those who were crowned Emperors by the Pope controlled only territories in Italy. The last of such Emperors was Berengar I of Italy, who died in 924.
Charlemagne, and the subsequent Holy Roman Emperors, were not, and did not claim to be, rulers of a restored Western Roman Empire. Pope Leo III and contemporary historians were fully aware of that the notion of a separate Western court had been abolished over three centuries prior and considered the Roman Empire to be "one and indivisible". The ruler of the Roman Empire at the time of Charlemagne's coronation was Irene, the mother of emperor Constantine VI who she had deposed. Leo III considered Irene to be a usurper and illegitimate to rule due to her gender and as such considered the imperial throne to be vacant. Thus, Charlemagne was not crowned as the ruler of the Western Roman Empire and successor to Romulus Augustulus, but rather as the successor of Constantine VI and as sole Roman Emperor. Irene was deposed and replaced by Emperor Nikephoros soon after, and the Eastern Empire refused to recognize the Imperial title of Charlemagne. Following several wars in the 810s Emperor Michael I Rangabe eventually recognized Charlemagne as an "Emperor", but as the slightly humiliating "Emperor of the Franks" rather than "Roman Emperor", a title he reserved for himself. For centuries to come, the "revived" Western court and the Eastern court, in direct succession to the Roman Emperors of old, would make competing claims to be rulers of the whole Roman Empire. With the Eastern Empire terming the Holy Roman Empire as an "Empire of the Franks", the term "Empire of the Greeks" was popularized in the Frankish court as a way to refer to the Empire centered in Constantinople.
In 1804, Napoleon Bonaparte declared the First French Empire. In response to this, Holy Roman Emperor Francis II of the Habsburg dynasty declared his personal domain to be the Austrian Empire and became Francis I of Austria. Taking the colours of the banner of the Holy Roman Emperor, the flag of the Austrian Empire was black and gold. Francis II was the last Holy Roman Emperor, with Napoleon forcing the empire's dissolution in 1806. After this point, these colours continued to be used as the flag of Austria until 1918.
In 395 Theodosius I, who had made Christianity the official religion of the Roman Empire, would be the last emperor to preside over a united Roman Empire. The empire was split into two halves: the Western Roman Empire centred in Ravenna, and the Eastern Roman Empire (later to be referred to as the Byzantine Empire) centred in Constantinople. The Roman Empire was repeatedly attacked by Hunnic, Germanic, Slavic and other “barbarian” tribes (see: Migration Period), and in 476 finally the Western part fell to the Heruli chieftain Odoacer.
After Charles V, Holy Roman Emperors assumed the title of "king of the Romans" at the same time as being elected emperor.
The titles of "Roman Emperor elect" ("erwählter Römischer Kaiser") and "king in Germany" ("König in Germanien")
continued to be used as part of the full style of the emperors until 1806.
When Francis II founded the Austrian Empire in 1804, he used as his style for the last two years before the dissolution of the Holy Roman Empire:
