Death of King Robert

King Robert Baratheon is mortally wounded by a boar while hunting. Before dying, he names Eddard Stark as Protector of the Realm and regent for his heir, Joffrey. Eddard writes a will, altering the wording to say 'my heir' instead of 'my son Joffrey,' knowing the truth. Robert's death triggers a power struggle, as Cersei moves to secure the throne for Joffrey. This event is a turning point, leading to the Lannister coup.
