The Peakes supported House Blackfyre during the First and Second Blackyre Rebellions. After the first, they were stripped of Dunstonbury and Whitegrove, and Lord Gormon Peake was executed after the failure of the second.
The Peakes rose up against King Maekar I Targaryen during the first half of the third century after the conquest. It is unknown which Peake lord rose up against the Targaryens, or whether there were any more factors involved than those already stated.
The King himself rode to the Dornish Marches to quash the uprising. He was, however, killed during the conflict, having his head caved in by a stone thrown from the battlements of Starpike. Lord Robert Reyne and Ser Tywald Lannister were also killed during the Storming of Starpike.
Lord Roger Reyne, Robert's heir and the new lord of Castamere, killed seven members of House Peake in retaliation for the death of his father. Prince Aegon Targaryen, Maekar's youngest son, prevented the murder of any more of the captives.
The death of Maekar threw the realm into a state of chaos. Maekar's oldest two children had died before their father, leaving the third son, Aemon, as heir. Aemon had taken the vows of a maester, however, and opted to go to The Wall over becoming the king, leaving Maekar's youngest son, Aegon, who was named king after a Great Council. For this, Aegon became known as Aegon the Unlikely.
