Page "Andronikos III Palaiologos" Paragraph 2

In 1320, Andronikos accidentally murdered his brother Manuel, whereupon their father died of grief.

The murder, and the general dissolute behaviour of Andronikos and his coterie, mostly the young scions of the Empire's great aristocratic clans, resulted in a deep rift in the relations between him and his grandfather, Andronikos II Palaiologos.

The elder Andronikos disowned his grandson, whereupon Andronikos III fled the capital and rallied his supporters around him in Thrace.

From there he waged an intermittent civil war against his grandfather, which first secured him recognition of his post as co-emperor, and ultimately led to the deposition of Andronikos II in 1328.
