The War of the Five Kings is a major civil war in the Seven Kingdoms of Westeros that erupts in the wake of the death of King Robert I. In essence, the war is at first a three-way battle for the Iron Throne fought alongside two independence movements. The five kings in question are Robert's heir apparent, Joffrey Baratheon, Robert's two younger brothers, Stannis and Renly Baratheon, the "King in the North" Robb Stark, and the "King of the Iron Islands" Balon Greyjoy.
