Marcian was Roman emperor of the East from 450 to 457. Very little of his life before becoming emperor is known, other than that he was a domesticus who served under the commanders Ardabur and his son Aspar for fifteen years. After the death of Emperor Theodosius II on 28 July 450, Marcian was made a candidate for the throne by Aspar, who held much influence because of his military power. After a month of negotiations Pulcheria, Theodosius' sister, agreed to marry Marcian. Zeno, a military leader whose influence was similar to Aspar's, may have been involved in these negotiations, as he was given the high-ranking court title of patrician upon Marcian's accession. Marcian was elected and inaugurated on 25 August 450.
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.
Valentinian III was Roman emperor in the West from 425 to 455. Made emperor in childhood, his reign over the Roman Empire was one of the longest, but was dominated by powerful generals vying for power amid civil wars and the invasions of Late antiquity's Migration Period, including the campaigns of Attila the Hun.
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.
Aetius was a Roman general and statesman of the closing period of the Western Roman Empire. He was a military commander and the most influential man in the Empire for two decades (433–454). He managed policy in regard to the attacks of barbarian federates settled throughout the West. Notably, he mustered a large Roman and allied (foederati) army in the Battle of the Catalaunian Plains, ending a devastating invasion of Gaul by Attila in 451, though the Hun and his subjugated allies still managed to invade Italy the following year, an incursion best remembered for the ruthless Sack of Aquileia and the intercession of Pope Leo I.
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.
Licinia Eudoxia was a Roman Empress, daughter of Eastern Roman Emperor Theodosius II. Her husbands included the Western Roman Emperors Valentinian III and Petronius Maximus.
Theodoric I was the King of the Visigoths from 418 to 451. Theodoric is famous for his part in stopping Attila at the Battle of the Catalaunian Plains in 451, where he was killed.
