Leontia then married Marcian, a son of Emperor Anthemius and Marcia Euphemia.

The following year the two consuls were Anthemius ' son, Marcian, and Leo's son-in-law, Flavius Zeno ( later successor of Leo on the Eastern throne ).

In 471, the year in which Leo held his fourth consulate with the Praetorian prefect of Italy Caelius Aconius Probianus as colleague, the two emperors strengthened their bonds with a marriage between Anthemius ' son, Marcian, and Leo's daughter, Leontia ; Marcian was honoured with his second consulate the following year, this time chosen by the Eastern court.

Leontia then married Marcian, a son of Anthemius and Marcia Euphemia.

In 478-479, the revolt of Marcian, a son of Anthemius took place.

Marcian and his brothers Procopius and Romulus launched their coup d ' état in Constantinople.

He had left no sons and two daughters, the elder Ariadne, born before Leo was raised to the throne and married to the Isaurian general Zeno, and the younger Leontia, born when Leo was already emperor and married to Procopius ' brother, Marcian.

With the help of some monks, they tried to escape, but Marcian failed, while Procopius fled in Thrace to Theodoric Strabo ( who refused to handle him to Zeno ) and then at Rome.

* Anthemius marries Marcia Euphemia, daughter of Marcian, and is elevated to the rank of comes.

Marcia Euphemia was the only known daughter of Marcian, and she was married to Anthemius, later Western Roman Emperor.

This succession of honourable events – the wedding with Marcian's daughter ; a promotion to an important military rank, but with administrative rather than military tasks ; the prestigious rank of patricius and the highest military position ; the consulate held with an Emperor as colleague – suggests that Marcian had selected Anthemius as a possible candidate for the Eastern or Western throne.

This hypothesis is further strengthened by the fact that Anthemius ' prestige misled the 6th century historian John Malalas to state that Marcian had actually designated Anthemius as Western Emperor after Avitus.

In October 456, in fact, the Western Emperor Avitus had been deposed ; it is probable that Marcian considered Anthemius as successor, but the Eastern Emperor died in January 457 before choosing his colleague.

Later on a granddaughter of Valentinian III was married to Olybrius and Anthemius was a son-in-law of Marcian.

Marcian was dispatched with his unit for a war against the Sassanids ( probably the Roman-Sassanid war of 421 – 422 ), but along the road East he fell ill in Lycia ; at this time he might have already been tribunus and commander of his unit.

In 431 / 434, while fighting in Africa under Aspar, Marcian was taken prisoner by the Vandals ; according to a later legend, he was brought before King Geiseric ( 428 – 477 ), who knew by an omen that Marcian was to be Emperor and was released on his oath never to take up arms against the Vandals.

Avitus was dead and the Western throne without a pretender ; the Eastern Roman Emperor was to choose the successor, but Marcian could not do anything, as he died on January 27, 457.

Sargon II became co-regent with Shalmaneser V in 722 BC, and became the sole ruler of the kingdom of Babylonia in 722 BC after the death of Shalmaneser V. It is not clear whether he was the son of Tiglath-Pileser III or a usurper unrelated to the royal family.

Son of the magister Ardaburius, Aspar played a crucial role in his father's expedition in 424 to defeat the western usurper, Joannes of Ravenna, and to install Galla Placidia and her son, Valentinian III, in his place.

While Aemilian descended upon Rome along the Flaminian Way, Trebonianus Gallus and his son and colleague Volusianus had him proclaimed " enemy of the State " by the Roman senate, then exited Rome to meet the usurper ; this strategy is a clue that Aemilian's army was smaller than theirs, as it is probable that they did not expect the reinforcements to come in time, but trusted their larger army to win the clash.
