Meanwhile, Robb Stark, the Lord of Winterfell, is declared the King in the North by his bannermen in the wake of the execution of his father, on false charges of treason by Joffrey.[2] Robb had been in command of a host marching south to free his then-imprisoned father and to relieve a Lannister attack on the Riverlands. As the King in the North, Robb declares that the North and the Riverlands, ruled by his maternal grandfather Hoster Tully, are a sovereign Kingdom of the North no longer subject to the rule of the Iron Throne.
