Flavius Basiliscus was the brother of Verina,
Leo
I's widow. He was married to Aelia Zenonis and they had a son,
Marcus (Marcus was granted the rank of Caesar. Shortly afterwards
Marcus was made co-Augustus and two more obscure, younger sons of
Basiliscus, Leo and Zeno, were raised to be Caesars). Basiliscus
was in command of the disastrous expedition against the Vandals
led by
Gaiseric in 468. After his accession
in 474, Verina began to plot against
Zeno,
with the intention of replacing him with her brother. With the support
of Illus Basiliscus was acclaimed as Augustus on 9 January 475.
Zeno fled to Isauria, where he was pursued
by troops loyal to Illus and Basiliscus. Basiliscus rapidly lost
support as he was forced to make strong fiscal impositions to finance
the war against
Zeno. Then he issued an anti-Chalcedonian
law in 475. Due to this he lost the support of the Constantinopolitan
Church and population.
Basiliscus also failed to keep promises made to Illus and he turned
against him supporting the return of
Zeno.
In August 476 Zeno marched back on Constantinople. Basiliscus and
his family took refuge in a church.
Zeno
promised not to execute them, so he exiled them to Cappadocia and
subsequently beheaded them.
Coinage
Although Marcus was raised to Augustus by his father his portrait
does not appear in any coin although his name does.
