Overview
Marcus (Greek: Μάρκος, died August 476) was the son of the Eastern Roman general and usurper Basiliscus and Zenonis. He was acclaimed caesar in 475 and later promoted to augustus, ruling as junior co-emperor to his father. When Zeno reoccupied Constantinople in late August 476, Marcus, with his parents, hid in a church. Zeno swore he would not spill their blood, and instead had them exiled to Limnae in Cappadocia, where they were then starved to death.
History
Rise to power
Marcus was the son of Basiliscus and Zenonis. When Byzantine Emperor Leo (457–474) fell ill in 473, he had his grandson, Leo II ( 474), the son of Zeno (474–475, 476–491) and Ariadne, crowned as emperor in October 473. Leo died on 18 January 474, and Leo II took the throne. Zeno was installed as co-emperor, crowned on 29 January, and when Leo II died in Autumn, Zeno became the sole eastern emperor. Zeno was very unpopular, among both the common people and the senatorial class, in part simply because he was an Isaurian, a race that had acquired a poor reputation under Emperor Arcadius (383–408), and also because his rule would induce a promotion of fellow Isuarians to high positions. Although Verina had supported Zeno's elevation as co-emperor to Leo II, she turned against him once he became sole emperor. Verina conspired with others to remove him as emperor, and historians generally accept that she planned to install her lover, the Patricius, as emperor and to marry him. She was supported in this plot by the general Theoderic Strabo, angered by Zeno's coronation, and Marcus' father Basiliscus, who succeeded in recruiting Illus and Trocundes, Isaurian brothers, as well as her nephew Armatus. The plot had the backing of the military, bolstered by Basiliscus' popularity, and that of Illus and Trocundes, and also the support of the Eastern Roman Senate. The position of the Patriarch of Constantinople, Acacius, is unclear, although the historian Kamilla Twardowska considers it likely that he would have withheld support from either side until the outcome was clear. The exact date the conspiracy began is unknown: historian Maciej Salamon argues it began around 473, whereas Twardowska argues it began only after Zeno took sole power. The conspiracy was successful, as Zeno fled to his native Isauria on 9 January 475, either after learning of the conspiracy or after being convinced by Verina that his life was in danger.
