Leo was born in the Balkans, ca. 401, with different sources suggesting Thracia or Dacia. He married Verina before becoming emperor and they had three children. Ariadne was born before Leo became emperor; a second daughter Leontia was born in 457, and an anonymous son died at age five months in 463. Ariadne married Leo's eventual successor, Zeno while Leontia married the son of Anthemius, Marcian (named after Anthemius' father-in-law, the emperor Marcian). Leo's early career was military, and he had reached the rank of tribune in the regiment of the Mattiarii by 457. With the death of the emperor Marcian in 457, Leo was acclaimed emperor, probably with the support of the magister militum Aspar. This involved passing over Marcian's son-in-law, Anthemius. Leo's coronation on February 7, 457 is the first known involving the patriarch of Constantinople as well as the army and Senate. Leo died of dysentery aged 73, on 18 January, 474. He was succeeded by his son, Leo II
Foreign Events
The peace treaty Theodosius II had made with the Sassanid Persians continued, leaving three major areas of concern in foreign policy, the Balkans, the Vandals and the Western Empire. With the disintegration of Attila's Empire, two Gothic groups, under Theoderic Strabo and Valamir, moved into the Balkans. Hostilities by Valamir in the western Balkans in 459 led to a negotiated peace with the Romans giving a small subsidy in exchange for peace and a hostage. At the same time, new barbarian groups, the Avars, Slavs and Bulgars, began filtering into the Transdanubian region. This in turn put increased pressure on Roman forces holding the Danube. Roman campaigning under Leo continued against the groups within and beyond the empire, especially against those Huns were under the leadership of Dengizech until his death in 469. The Goths led by Theoderic Strabo, who was appointed magister militum praesentalis in 473, were able to reach a dominant position in the eastern Balkans. His success threatened Valamir's Goths, now led by Valamir's son Theoderic, who moved east to challenge Strabo shortly before Leo died. Outside the Balkans, the Vandals were also a serious problem and in 468 a major Roman offensive was launched against them. This involved a naval expedition, supported by troops marching overland from Egypt and by western Roman troops under Marcellinus. The expedition was led by Leo's brother-in-law, Basiliscus, but turned out to be a disaster. As well as having little military effect, the expedition was tremendously expensive. Lastly, Leo had great influence in the west and was able to approve Ricimer's appointment of Majorian as western Emperor in 457. A decade later, 467 Leo sent Anthemius, who had married the daughter of the previous emperor, Marcian, as Emperor for the west. In 474, after the death of Olybrius, Leo sent an expedition to Italy under Julius Nepos to expel Olybrius' successor, Glycerius. There were also minor military problems in the Caucasus and Arabian regions.
Domestic and Religious Affairs
After Leo's acclamation, the early domestic events
concerned religion. In 460, the Alexandrians elected a
monophysite patriarch, Timothy Aelurus ("the Cat").
After consulting bishops throughout the east, Leo removed
Timothy by force, replacing him with Timothy Salofaciolus
(the Greek means either "White-Hat" or
"Wobble-Hat"). Constantinople was devastated by a
major fire in 464. During the early part of Leo's reign, the magister
militum Aspar was a prominent figure and probably
instrumental in Leo's accession. This position was weakened
when Aspar's son, Ardabur, was found guilty of treachery in
466 and dismissed from office. Leo then married his eldest
daughter, Ariadne, to Zeno,
probably in 466, Aspar, however, continued to be influential.
In 467, the pagan Isocasius, a court official, was arrested
and accused of being a Hellene (i.e. pagan). Although he was
acquitted of the charges, this probably led to Leo's issuing
a law in 468 which banned pagans from being lawyers. At this
period probably occurred the creation of a new guard
regiment, the excubitores, which in its early stages
at least, was dominated by Isaurians. Although Aspar's
dominance and been weakened, he was able to reassert himself
after the failure of the Vandal expedition of 468 and
prevailed upon Leo to declare his son, Patricius,
as Caesar in 470. When the magister militum
Anagastes revolted in Thrace in 470 negotiations with Leo
revealed that the rebellion was encouraged by Ardabur. Leo
eventually decided that Ardabur was too dangerous to let
live. Aspar and Ardabur and probably Patricius
were murdered in the palace in 471, from which Leo acquired
the nickname "M
",
meaning "the Butcher". Following the murders, there
was a persecution of the Arians who had supported Aspar. For
the rest of the reign, Zeno,
as Leo's son-in-law, was the dominant figure.
