War of the Ninepenny Kings

Westeros | Essos | Events | Military Orders

The War of the Ninepenny Kings, also known as the Fifth Blackfyre Rebellion, was a war fought in the Stepstones, east of Westeros, between King Jaehaerys II Targaryen and the Band of Nine, a motlew crew of merchants, mercenaries and pirates led by Maelys I Blackfyre, in 260 AC.
Multiple clashes in the Stepstones occurred after King Jaehaerys II authorized an expedition to the Stepstones to prevent Maelys the Monstrous from successfully claiming the Iron Throne.
The war ended with Jaehaerys II and the Targaryens triumphant, and the patrilineal extinction of House Blackfyre.
Information about the war can be found in George R.R. Martin's The World of Ice and Fire, and is referenced on multiple occasions in the main series, A Song of Ice and Fire.
