The First Blackfyre Rebellion, known to contemporaries as the Blackfyre Rebellion, was a war fought between the loyalist forces of King Daeron II Targaryen and the rebel forces of his half-brother, Daemon I Blackfyre. Conflict arose when Daemon, a bastard son of the late King Aegon IV Targaryen, claimed the throne of his older, trueborn brother, King Daeron II Targaryen, which resulted in open civil war that divided the Seven Kingdoms.
