<P> Joffrey finally marries Margaery . During his wedding feast in the gardens of the Red Keep , he presents an extremely offensive play of `` The War of the Five Kings , '' with each of the kings played by dwarves , to humiliate his uncle . He also repeatedly torments Tyrion and Sansa , forcing the former to be his cupbearer . At the height of festivities Joffrey is suddenly overcome by poison , and he dies . His uncle Tyrion is accused and arrested . It is confirmed , however , he was poisoned by Olenna Tyrell , with assistance from Petyr Baelish and Dontos Hollard , as she wanted to protect Margaery from the physical and emotional abuse that Joffrey had very clearly inflicted on Sansa . Olenna later confides to Margaery that she would never have let her marry `` that monster '' . Following Joffrey 's funeral , his younger brother and heir , Tommen , is crowned King and proceeds to marry Joffrey 's widow Margaery . </P>
