House Blackfyre is a noble family in the fictional world of A Song of Ice and Fire, created by George R.R. Martin. They are a cadet branch of House Targaryen, founded by Daemon Blackfyre, a legitimized bastard of King Aegon IV. The family is known for their black dragon sigil and their claim to the Iron Throne, which led to several civil wars known as the Blackfyre Rebellions. The Blackfyres are often associated with ambition and conflict, as their desire to reclaim the throne puts them at odds with the ruling House Targaryen. Over time, the family faced numerous challenges, including betrayals and defeats, which ultimately led to their decline. Despite this, the legacy of House Blackfyre continues to influence the political landscape of Westeros.
