Year 456 (CDLVI) was a leap year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Avitus without colleague. The denomination 456 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.
Ricimer was a Romanized Germanic general who effectively ruled the remaining territory of the Western Roman Empire from 456 after defeating Avitus, until his death in 472, with a brief interlude in which he contested power with Anthemius. Deriving his power from his position as magister militum of the Western Empire, Ricimer exercised political control through a series of puppet emperors. Ricimer's death led to unrest across Italy and the establishment of a Germanic kingdom on the Italian Peninsula.
Majorian, was the Western Roman emperor from 457 to 461. A prominent commander in the Western military, Majorian deposed Avitus in 457 with the aid of his ally Ricimer. Possessing little more than Italy, Dalmatia, as well as some territory in Hispania and northern Gaul, Majorian campaigned rigorously for three years against the Empire's enemies. In 461, he was murdered at Dertona in a conspiracy, and his successors until the Fall of the Empire in 476 were puppets either of barbarian generals or the Eastern Roman court.
Procopius Anthemius was the Western Roman emperor from 467 to 472. Born in the Eastern Roman Empire, Anthemius quickly worked his way up the ranks. He married into the Theodosian dynasty through Marcia Euphemia, daughter of Eastern emperor Marcian. He soon received a significant number of promotions to various posts, and was presumed to be Marcian's planned successor. However, Marcian's sudden death in 457, together with that of Western emperor Avitus, left the imperial succession in the hands of Aspar, who instead appointed a low-ranking officer known as Leo to the Eastern throne out of fear that Anthemius would be too independent. Eventually, this same Leo would designate Anthemius as Western emperor in 467, following a two-year interregnum that started in 465.
Eparchius Avitus was Roman emperor of the West from July 455 to October 456. He was a senator of Gallic extraction and a high-ranking officer both in the civil and military administration, as well as Bishop of Piacenza.
Gundobad was King of the Burgundians, succeeding his father Gundioc of Burgundy. Previous to this, he had been a patrician of the moribund Western Roman Empire in 472 – 473, three years before its collapse, succeeding his uncle Ricimer. He is perhaps best known today as the probable issuer of the Lex Burgundionum legal codes, which synthesized Roman law with ancient Germanic customs. He was the husband of Caretene.
The term Western Roman Empire is used in modern historiography to refer to the western provinces of the Roman Empire, collectively, during any period in which they were administered separately from the eastern provinces by a separate, independent Imperial court. Particularly during the period from 395 to 476 AD, there were separate, coequal courts dividing the governance of the empire into the Western provinces and the Eastern provinces with a distinct imperial succession in the separate courts. The terms Western Roman Empire and Eastern Roman Empire were coined in modern times to describe political entities that were de facto independent; contemporary Romans did not consider the Empire to have been split into two empires but viewed it as a single polity governed by two imperial courts for administrative expediency. The Western Roman Empire collapsed in 476, and the Western imperial court in Ravenna was formally dissolved by Justinian I in 554 AD.
Marcellinus was a Roman general and patrician who ruled over the region of Dalmatia in the Western Roman Empire and held sway with the army there from 454 until his death.
The Vandalic War was a conflict fought in North Africa between the forces of the Byzantine Empire and the Vandalic Kingdom of Carthage in 533–534. It was the first of Justinian I's wars of the reconquest of the Western Roman Empire.
Libius Severus, sometimes enumerated as Severus III, was emperor of the Western Roman Empire from 461 to his death in 465. A native of Lucania, Severus was the fourth of the so-called Shadow Emperors who followed the deposition of the Valentinianic dynasty in 455. He ruled for just under four years, attaining the throne after his predecessor, Majorian, was overthrown by his magister militum, Ricimer. Severus was the first of a series of emperors who were highly dependent on the general, and it is often presumed that Ricimer held most of the de facto power during Severus' reign
Gaiseric, also known as Geiseric or Genseric was king of the Vandals and Alans from 428 to 477. He ruled over a kingdom and played a key role in the decline of the Western Roman Empire during the 5th century.
Remistus was a general of the Western Roman Empire, commander-in-chief of the army under Emperor Avitus.
The Battle of Cape Bon was an engagement during a joint military expedition of the Western and Eastern Roman Empires led by Basiliscus against the Vandal capital of Carthage in 468. The invasion of the kingdom of the Vandals was one of the largest amphibious operations in antiquity, with 1,113 ships and over 50,000 personnel.
Odoacer's deposition of Romulus Augustus, occurring in 476 AD, was a coup that marked the end of the reign of the Western Roman Emperor last approved by the Western Roman Senate and the creation of the Kingdom of Italy, although Julius Nepos exercised control over Dalmatia until 480.
The Battle of Agrigentum was fought in 456 A.D. at Agrigentum, now Agrigento in modern-day Sicily. An army of the Western Roman Empire, led by the general Ricimer, drove off an invading force, a fleet of sixty ships, sent by the Vandal king Gaiseric to raid Sicily. Ricimer then led the Roman fleet against the Vandals and defeated them in a naval battle off the coast of Corsica. The victory gave the Romans only temporary relief from Vandal raids.
Vandal Sardinia covers the history of Sardinia from the end of the long Roman domination in 456, when the island was conquered by the Vandals, a Germanic population settled in Africa Proconsularis and Mauretania Caesariensis, until its reconquest by the Byzantine Roman Emperor Justinian in 534.
The Battle of Campi Canini was fought between the Alemanni and the Western Roman Empire in 457. Taking advantage of the confusion after the defeat of Emperor Avitus at Placentia on 16 October 456, an Alemannic army crossed the Rhaetian Alps through Switzerland into Italy, reaching Lake Maggiore. At nearby Campi Cannini, the Alemanni were defeated by the Roman officer Burco, in the name of the usurper Majorian.
