Magnentius was an usurper of the Roman Empire from 350 to 353. Born in Samarobriva, Magnentius was the commander of the Herculians and Jovians, the Imperial guard units; when the army grew dissatisfied with the behavior of Emperor Constans, it elevated Magnentius at Autun on January 18, 350. Constans was abandoned by all except a handful of retainers, he was slain shortly afterwards by a troop of light cavalry near the Pyrenees. Magnentius attracted the loyalty of the provinces in Britannia and Hispania, in part because he proved to be far more tolerant towards both Christians and Pagans, his control of Italia and Africa was secured through the election of his men to the most important offices. However, the short-lived revolt of Nepotianus, a member of the Constantinian dynasty, showed Magnentius that his status as emperor needed to be consolidated. Magnentius tried to strengthen his grasp on the territories controlled by Constans, moving towards the Danube. Vetranio, commander of the Pannonian army, had been elected Augustus by his troops in Mursa on 1 March.
This revolt had a loyalist mark, since Vetranio was supported by Constantina, Constantius II himself recognized Vetranio, sending him the imperial diadem. The remaining emperor of the family of Constantine I, Constantius II, broke off his war with Persia, marched west from Syria. Despite Magnentius' efforts to win Vetranio over to his cause, the elderly Vetranio reached Constantius with his army, resigned the crown, went into retirement in Bithynia. After electing Magnus Decentius as Caesar and gathering as many troops as possible, Magnentius advanced his armies to meet those of Constantius in the Battle of Mursa Major in 351. Despite Magnentius' heroism, his troops were forced to retreat back to Gaul; as a result of Magnentius' defeat, Italy rejoined the loyalist cause. Magnentius made a final stand in 353 at the Battle of Mons Seleucus, after which he committed suicide by falling on his sword. Following the suppression of Magnentius' rebellion, Constantius began to root out his followers; the most notorious agent he employed in this search was the primicerius notariorum Paulus Catena.
Some sources state that Magnentius' father was his mother a Frank. Gibbon gives that he was born in one of the colonies of Franks or Alemans founded by Constantius' grandfather, Constantius I. in Gaul. His wife, Justina married Valentinian I.

Flavius Philippus was an official under the Roman Emperor Constantius II. Son of a sausage-maker, Philippus rose in social standing. In 346, he became Praetorian Prefect of the East under Emperor Constantius because of the influence of the court eunuchs. Philippus obtained the consulate in 348. In 351, when Constantius was facing the rebellion of the usurper Magnentius, Philippus was sent to the rebel camp, formally to negotiate a peace, but to discover the military readiness of the enemy. Philippus addressed the rebel army, accusing them of ingratitude towards the Constantinian dynasty, proposing that Magnentius leave Italy and keep only Gaul; when Magnentius tried to take the town of Siscia, Philippus was held hostage by the usurper. It is unknown whom he married, but his grandson, Flavius Anthemius became Praetorian Prefect of the East. Libanius, xlii, lxxii. Zosimus, Historia Nova, ii.46.2-4.

Pannonia was a province of the Roman Empire bounded north and east by the Danube, coterminous westward with Noricum and upper Italy, southward with Dalmatia and upper Moesia. Pannonia was located over the territory of the present-day western Hungary, eastern Austria, northern Croatia, north-western Serbia, northern Slovenia, western Slovakia and northern Bosnia and Herzegovina. Julius Pokorny believed the name Pannonia is derived from Illyrian, from the Proto-Indo-European root *pen-, "swamp, wet". Others believe that the name is related to the god of the nature and shepherds Pan and/or pan, the Proto-Slavic/Proto-Indo-European word for lord/master, which could mean Pan's Land or Land of the Master, more probable due the fact the Ionian fleet supplied Pannonia via the Black Sea and Danube, Panionium festivities were well known in the region to its Celtic, Adriatic Veneti and Scythian inhabitants. Pliny the Elder, in Natural History, places the eastern regions of the Hercynium jugum, the "Hercynian mountain chain", in Pannonia and Dacia.
He gives us some dramaticised description of its composition, in which the close proximity of the forest trees causes competitive struggle among them. He mentions its gigantic oaks, but he—if the passage in question is not an interpolated marginal gloss—is subject to the legends of the gloomy forest. He mentions unusual birds, which have feathers that "shine like fires at night". Medieval bestiaries named these birds the Ercinee; the impenetrable nature of the Hercynian Silva hindered the last concerted Roman foray into the forest, by Drusus, during 12–9 BC: Florus asserts that Drusus invisum atque inaccessum in id tempus Hercynium saltum patefecit. The first inhabitants of this area known to history were the Pannonii, a group of Indo-European tribes akin to Illyrians. From the 4th century BC, it was invaded by various Celtic tribes. Little is heard of Pannonia until 35 BC, when its inhabitants, allies of the Dalmatians, were attacked by Augustus, who conquered and occupied Siscia; the country was not, definitively subdued by the Romans until 9 BC, when it was incorporated into Illyricum, the frontier of, thus extended as far as the Danube.
In AD 6, the Pannonians, with the Dalmatians and other Illyrian tribes, engaged in the so-called Great Illyrian Revolt, were overcome by Tiberius and Germanicus, after a hard-fought campaign, which lasted for three years. After the rebellion was crushed in AD 9, the province of Illyricum was dissolved, its lands were divided between the new provinces of Pannonia in the north and Dalmatia in the south; the date of the division is unknown, most after AD 20 but before AD 50. The proximity of dangerous barbarian tribes necessitated the presence of a large number of troops, numerous fortresses were built on the bank of the Danube; some time between the years 102 and 107, between the first and second Dacian wars, Trajan divided the province into Pannonia Superior, Pannonia Inferior. According to Ptolemy, these divisions were separated by a line drawn from Arrabona in the north to Servitium in the south; the whole country was sometimes called the Pannonias. Pannonia Superior was under the consular legate, who had administered the single province, had three legions under his control.
Pannonia Inferior was at first under a praetorian legate with a single legion as the garrison. The frontier on the Danube was protected by the establishment of the two colonies Aelia Mursia and Aelia Aquincum by Hadrian. Under Diocletian, a fourfold division of the country was made: Pannonia Prima in the northwest, with its capital in Savaria / Sabaria, it included Upper Pannonia and the major part of Central Pannonia between the Raba and Drava, Pannonia Valeria in the northeast, with its capital in Sopianae, it comprised the remainder of Central Pannonia between the Raba and Danube, Pannonia Savia in the southwest, with its capital in Siscia, Pannonia Secunda in the southeast, with its capital in SirmiumDiocletian moved parts of today's Slovenia out of Pannonia and incorporated them in Noricum. In 324 AD, Constantine I enlarged the borders of Roman Pannonia to the east, annexing the plains of what is now eastern Hungary, northern Serbia and western Romania up to the limes that he created: the Devil's Dykes.
In the 4th-5th century, one of the dioceses of the Roman Empire was known as the Diocese of Pannonia. It had its capital in Sirmium and included all four provinces that were formed from historical Pannonia, as well as the provinces of Dalmatia, Noricum Mediterraneum and Noricum Ripense. During the Migrations Period in the 5th century, some parts of Pannonia was ceded to the Huns in 433 by Flavius Aetius, the magister militum of the Western Roman Empire. After the collapse of the Hunnic empire in 454, large numbers of Ostrogoths were settled by Marcian in the province as foederati; the Eastern Roman Empire controlled it for a time in the 6th century, a Byzantine province of Pannonia with its capital at Sirmium was temporarily restored, but it included only a small southeastern part of historical Pannonia. Afterwards, it was again invaded by the Avars in the 560s, the Slavs, who first settled c. 480s but became independent only from the 7th century, the Franks, who named a frontier march the March of Pannonia in the late 8th century.
The term Pannonia wa
The Roman Empire was the post-Roman Republic period of the ancient Roman civilization. Ruled by emperors, it had large territorial holdings around the Mediterranean Sea in Europe, North Africa, the Middle East, the Caucasus. From the constitutional reforms of Augustus to the military anarchy of the third century, the Empire was a principate ruled from the city of Rome; the Roman Empire was ruled by multiple emperors and divided in a Western Roman Empire, based in Milan and Ravenna, an Eastern Roman Empire, based in Nicomedia and Constantinople. Rome remained the nominal capital of both parts until 476 AD, when Odoacer deposed Romulus Augustus after capturing Ravenna and the Roman Senate sent the imperial regalia to Constantinople; the fall of the Western Roman Empire to barbarian kings, along with the hellenization of the Eastern Roman Empire into the Byzantine Empire, is conventionally used to mark the end of Ancient Rome and the beginning of the Middle Ages. The previous Republic, which had replaced Rome's monarchy in the 6th century BC, became destabilized in a series of civil wars and political conflict.
In the mid-1st century BC Julius Caesar was appointed as perpetual dictator and assassinated in 44 BC. Civil wars and proscriptions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC; the following year Octavian conquered Ptolemaic Egypt, ending the Hellenistic period that had begun with the conquests of Alexander the Great of Macedon in the 4th century BC. Octavian's power was unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title Augustus making him the first emperor; the first two centuries of the Empire were a period of unprecedented stability and prosperity known as the Pax Romana. It reached its greatest territorial expanse during the reign of Trajan. A period of increasing trouble and decline began with the reign of Commodus. In the 3rd century, the Empire underwent a crisis that threatened its existence, but was reunified under Aurelian. In an effort to stabilize the Empire, Diocletian set up two different imperial courts in the Greek East and Latin West.
Christians rose to power in the 4th century following the Edict of Milan in 313 and the Edict of Thessalonica in 380. Shortly after, the Migration Period involving large invasions by Germanic peoples and the Huns of Attila led to the decline of the Western Roman Empire. With the fall of Ravenna to the Germanic Herulians and the deposition of Romulus Augustulus in 476 AD by Odoacer, the Western Roman Empire collapsed and it was formally abolished by emperor Zeno in 480 AD; the Eastern Roman Empire, known in the post-Roman West as the Byzantine Empire, collapsed when Constantinople fell to the Ottoman Turks of Mehmed II in 1453. Due to the Roman Empire's vast extent and long endurance, the institutions and culture of Rome had a profound and lasting influence on the development of language, architecture, philosophy and forms of government in the territory it governed Europe; the Latin language of the Romans evolved into the Romance languages of the medieval and modern world, while Medieval Greek became the language of the Eastern Roman Empire.
Its adoption of Christianity led to the formation of Christendom during the Middle Ages. Greek and Roman art had a profound impact on the late medieval Italian Renaissance, while Rome's republican institutions influenced the political development of republics such as the United States and France; the corpus of Roman law has its descendants in many legal systems of the world today, such as the Napoleonic Code. Rome's architectural tradition served as the basis for Neoclassical architecture. Rome had begun expanding shortly after the founding of the republic in the 6th century BC, though it did not expand outside the Italian peninsula until the 3rd century BC, it was an "empire" long before it had an emperor. The Roman Republic was not a nation-state in the modern sense, but a network of towns left to rule themselves and provinces administered by military commanders, it was ruled, not by annually elected magistrates in conjunction with the senate. For various reasons, the 1st century BC was a time of political and military upheaval, which led to rule by emperors.
The consuls' military power rested in the Roman legal concept of imperium, which means "command". Successful consuls were given the honorary title imperator, this is the origin of the word emperor since this title was always bestowed to the early emperors upon their accession. Rome suffered a long series of internal conflicts and civil wars from the late second century BC onward, while extending its power beyond Italy; this was the period of the Crisis of the Roman Republic. Towards the end of this era, in 44 BC, Julius Caesar was perpetual dictator before being assassinated; the faction of his assassins was driven from Rome and defeated at the Battle of Philippi in 42 BC by an army led by Mark Antony and Caesar's adopted son Octavian. Antony and Octavian's division of the Roman world between themselves did not last and Octavian's forces defeated those of Mark Antony and Cleopatra at the Battle of Actium in 31 BC, ending the Final War of the Roman Republic. In 27 BC the Senate and People of Rome made Octavian princeps ("first citi
Battle of Adrianople (324)
The Battle of Adrianople was fought on July 3, 324, during a Roman civil war, the second to be waged between the two emperors Constantine I and Licinius. Constantine had, in a previous war, defeated Licinius at the Battle of Cibalae and conquered from him all the Balkan Peninsula, with the exception of Thrace. A peace had been arranged but the relationship between the two emperors remained uneasy. By 324 Constantine was ready to renew the conflict and when his army, in pursuit of a raiding Visigothic, or Sarmatian, crossed into Licinius' territory an opportune casus belli was created; the reaction of Licinius to this incursion was overtly hostile and this induced Constantine to go on to the offensive. Constantine invaded Thrace in force. Licinius encamped his army in a strong position near the major city of inland Thrace. Constantine advanced eastward from Thessalonica until he came to the Hebrus River, on which Adrianople stands, set up his own camp. Licinius arranged his battle line, of 200 stades in length, in a strong position between a height overlooking the town and the confluence of the Hebrus with a tributary.
The two armies remained in position for a number of days before battle was joined, as both sides were reluctant to chance the crossing of the river against a well-prepared and battle-arrayed enemy. Constantine used a ruse to get his troops across the Hebrus. Having noticed a suitable crossing point where the river narrowed and was overlooked by a wooded hillside, he ordered material and ropes to be conspicuously assembled at another place on the river, well away from his chosen crossing, to give the impression that he intended to build a bridge to cross there. On the wooded hillside, he secretly assembled a force of cavalry, he led his cavalry over the river crossing at the narrows, fell on the enemy unexpectedly. The surprise attack was a complete success and the remainder of his army crossed at the same point. With his position on the river outflanked, Licinius' withdrew his forces and took up a defensive position on higher ground. However, this gave Constantine the initiative once more, his attack was again successful.
What followed, in the words of the historian Zosimus, was "a great massacre": Licinius' army, according to Zosimus, received losses of 34,000 dead. During the onslaught, Constantine directed the guard of his overtly Christian standard, the labarum, to move it to any part of the field where his troops seemed to be faltering; the appearance of this talisman dismayed those of Licinius. Constantine, wounded in the thigh, halted his attack at sunset and darkness allowed Licinius and the remains of his force to withdraw to Byzantium, the coast, the safety of his fleet; the battle was one of the largest of the 4th century. Though Zosimus attributes the success of the Constantinian forces to the courage and martial prowess of Constantine himself, whom he alleges to have led the cavalry in person in the charge which broke Licinus' defenses, other contemporary accounts ascribe his success to the discipline of the troops and Constantine's felicitas, his'good fortune'. Constantine's effort to start a civil conflict proved successful, as did his campaign against Licinius.
Following the battle at Adrianople, Constantine moved to besiege Byzantium. At this point in the campaign, control of the narrow waters separating Thrace and Asia Minor became of the utmost importance to both emperors. Constantine's son Crispus commanded his navy in a struggle with the larger fleet of Licinius. Following Crispus' naval victory in the waters of the Hellespont, Constantine crossed with his army into Bithynia, he met Licinius' army in the final battle of the war at Chrysopolis on the Asiatic shore of the Bosporus. Constantine won an overwhelming victory. Yielding to the pleas of his sister Constantia, Constantine spared the life of his brother-in-law, but some months he ordered his execution, thereby breaking his solemn oath. Licinius was suspected of the army command pressed for his execution. A year Constantine's nephew the younger Licinius fell victim to the emperor's anger or suspicions. Constantine became the first man to be master of the entire Roman world since the elevation of Maximian as co-emperor by Diocletian in 285.

Roman Britain was the area of the island of Great Britain, governed by the Roman Empire, from 43 to 410 AD. It comprised the whole of England and Wales and, for a short period, southern Scotland. Julius Caesar invaded Britain in 54 BC as part of his Gallic Wars. According to Caesar, the Britons had been overrun or culturally assimilated by other Celtic tribes during the British Iron Age and had been aiding Caesar's enemies, he received tribute, installed a friendly king over the Trinovantes, returned to Gaul. Planned invasions under Augustus were called off in 34, 27, 25 BC. In 40 AD, Caligula assembled 200,000 men at the Channel on the continent, only to have them gather seashells according to Suetonius as a symbolic gesture to proclaim Caligula's victory over the sea. Three years Claudius directed four legions to invade Britain and restore an exiled king over the Atrebates; the Romans defeated the Catuvellauni, organized their conquests as the Province of Britain. By the year 47, 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 northward. The conquest of Britain continued under command of Gnaeus Julius Agricola, who expanded the Roman Empire as far as Caledonia. In the summer of 84, Agricola faced the armies of the Caledonians, led by Calgacus, at the Battle of Mons Graupius. Battle casualties were estimated by Tacitus to be around the 10,000's on the Caledonian side and about 360 on the Roman side; the bloodbath at Mons Graupius concluded the forty-year conquest of Britain, a period that saw between 100,000 and 250,000 Britons killed. In the context of pre-industrial warfare and of a total population of Britain of c.2 million, these are high figures. Under the 2nd-century emperors Hadrian and Antoninus Pius, two walls were built to defend the Roman province from the Caledonians, whose realms in the Scottish Highlands were never controlled. Around 197, the Severan Reforms divided Britain into two provinces: Britannia Superior and Britannia Inferior.
During the Diocletian Reforms, at the end of the 3rd century, Britannia was divided into four provinces under the direction of a vicarius, who administered the Diocese of the Britains. A fifth province, Valentia, is attested in the 4th century. For much of the period of the Roman occupation, Britannia was subject to barbarian invasions and came under the control of imperial usurpers and imperial pretenders; the final Roman withdrawal from Britain occurred around 410. Following the conquest of the Britons, a distinctive Romano-British culture emerged as the Romans introduced improved agriculture, urban planning, industrial production, architecture; the Roman goddess Britannia became the female personification of Britain. After the initial invasions, Roman historians only mention Britain in passing. Thus, most present knowledge derives from archaeological investigations and occasional epigraphic evidence lauding the Britannic achievements of an emperor. Roman citizens settled in Britain from many parts of the Empire.
Britain was known to the Classical world. The Greeks referred to the Cassiterides, or "tin islands", placed them near the west coast of Europe; the Carthaginian sailor Himilco is said to have visited the island in the 5th century BC and the Greek explorer Pytheas in the 4th. It was regarded with some writers refusing to believe it existed at all; the first direct Roman contact was when Julius Caesar undertook two expeditions in 55 and 54 BC, as part of his conquest of Gaul, believing the Britons were helping the Gallic resistance. The first expedition was more a reconnaissance than a full invasion and gained a foothold on the coast of Kent but was unable to advance further because of storm damage to the ships and a lack of cavalry. Despite the military failure it was a political success, with the Roman Senate declaring a 20-day public holiday in Rome to honour the unprecedented achievement of obtaining hostages from Britain and defeating Belgian tribes on returning to the continent; the second invasion involved a larger force and Caesar coerced or invited many of the native Celtic tribes to pay tribute and give hostages in return for peace.
A friendly local king, was installed, his rival, was brought to terms. Hostages were taken, but historians disagree over whether any tribute was paid after Caesar returned to Gaul. Caesar conquered no territory and left no troops behind but he established clients and brought Britain into Rome's sphere of influence. Augustus planned invasions in 34, 27 and 25 BC, but circumstances were never favourable, the relationship between Britain and Rome settled into one of diplomacy and trade. Strabo, writing late in Augustus's reign, claimed that taxes on trade brought in more annual revenue than any conquest could. Archaeology shows. Strabo mentions British kings who sent embassies to Augustus and Augustus's own Res Gestae refers to two British kings he received as refugees; when some of Tiberius's ships were carried to Britain in a storm during his campaigns in Germany in 16 AD, they came back with tales of monsters. Rome appears to have encouraged a balance of power in southern Britain, supporting two powerful kingdoms: the Catuvellauni, ruled by the descendants of Tasciovanus, the Atrebates, ruled by the descendants of Commius.
This policy was followed until 39 or 40
Augustus was an ancient Roman title given as both name and title to Gaius Octavius, Rome's first Emperor. On his death, it became an official title of his successor, was so used by Roman emperors thereafter; the feminine form Augusta was used for other females of the Imperial family. The masculine and feminine forms originated in the time of the Roman Republic, in connection with things considered divine or sacred in traditional Roman religion, their use as titles for major and minor Roman deities of the Empire associated the Imperial system and Imperial family with traditional Roman virtues and the divine will, may be considered a feature of the Roman Imperial cult. In Rome's Greek-speaking provinces, "Augustus" was translated as sebastos, or Hellenised as Augoustos. After the fall of the Roman Empire, Augustus was sometimes used as a name for men of aristocratic birth in the lands of the Holy Roman Empire, it remains a given name for males. Some thirty years before its first association with Caesar's heir, Augustus was an obscure honorific with religious associations.
One early context, associates it with provincial Lares. In Latin poetry and prose, it signifies the "elevation" or "augmentation" of what is sacred or religious; some Roman sources connected it to augury, Rome was said to have been founded with the "august augury" of Romulus. The first true Roman Emperor known as "Augustus" was Gaius Julius Caesar Octavianus, he was the adopted son and heir of Julius Caesar, murdered for his seeming aspiration to divine monarchy subsequently and deified. Octavian studiously avoided any association with Caesar's claims, other than acknowledging his position and duties as Divi filius, "son of the deified one", his position was unique and extraordinary. He had ended Rome's prolonged and bloody civil war with his victory at Actium, established a lasting peace, he was self-evidently favored by the gods. As princeps senatus he presided at senatorial meetings, he was chief priest of Roman state religion. He held consular imperium, with authority equal to the official chief executive, he was supreme commander of all Roman legions, held tribunicia potestas.
As a tribune, his person was inviolable and he had the right to veto any act or proposal by any magistrate within Rome. He was renamed Augustus by the Roman Senate on January 16, 27 BC – or the Senate ratified his own careful choice. So his official renaming in a form vaguely associated with a traditionally Republican religiosity, but unprecedented as a cognomen, may have served to show that he owed his position to the approval of Rome and its gods, his own unique, elevated, "godlike" nature and talents, his full and official title was Imperator Caesar Divi Filius Augustus. Augustus' religious reforms extended or affirmed augusti as a near ubiquitous title or honour for various minor local deities, including the Lares Augusti of local communities, obscure provincial deities such as the North African Marazgu Augustus; this extension of an Imperial honorific to major and minor deities of Rome and her provinces is considered a ground-level feature of Imperial cult, which continued until the official replacement of Rome's traditional religions by Christianity.
The title or name of Augustus was adopted by his successors, who held the name during their own lifetimes by virtue of their status and powers. This included the Christian emperors. Most emperors used imperator but others could and did bear the same title and functions. "Caesar" was used as a title, but was the name of a clan within the Julian line. Augusta was the female equivalent of Augustus, had similar origins as an obscure descriptor with vaguely religious overtones, it was bestowed on some women of the Imperial dynasties, as an indicator of worldly power and influence and a status near to divinity. There was no qualification with higher prestige; the title or honorific was shared by state goddesses associated with the Imperial regime's generosity and provision, such as Ceres, Bona Dea, Juno and Ops, by local or minor goddesses around the empire. Other personifications perceived as female and given the title Augusta include Pax and Victoria; the first woman to receive the honorific Augusta was Livia Drusilla, by the last will of her husband Augustus.
From his death she was known as Julia Augusta, until her own death in AD 29. Under Tetrarchy, the empire was divided into Western halves; each was ruled by a senior emperor, with the rank of augustus, a junior emperor, who ranked below him as a caesar. The Imperial titles of imperator and augustus were rendered in Greek as autokratōr, augoustos; the Greek titles were used in the Byzantine Empire until its extinction in 1453, although "sebastos" lost its imperial exclusivity and autokratōr became the exclusive title of the Byzantine Emperor. The last Roman Emperor to rule in the West, Romulus Augustus became known as Augustulus, due to the unimportance of his reign. Charlemagne used the title serenissimus augustus as a prefix to his titles His successors limited themselves to imperator augustus, in order to avoid conflict with the Byzantine emperors. Beginning with Otto III, the Holy Roman Emperors used Romanorum Imperator Augustus; the form
