House Greyjoy

House Greyjoy of Pyke is a Great House of Westeros that rules the archipelago of the Iron Islands from their seat of Pyke.

Formerly a vassal of House Greyiron and later House Hoare, the Greyjoys became the rulers of the Iron Islands following the extinction of House Hoare during Aegon's Conquest, having been elected by the other Ironborn houses to succeed them.

Despite his support for the rebels during the late stages of Robert's Rebellion, Lord Balon Greyjoy launched a rebellion against King Robert I Baratheon in 289 AC, declaring himself King of the Iron Islands, but the rebellion was quickly crushed by Robert's forces. Upon Robert's death, Balon rebelled again and attempted to invade the North, but saw minimal success. In 303 AC, Balon's brother Euron Greyjoy returned to the Iron Islands and killed him, sparking a civil conflict between the supporters of Euron and Balon's daughter Yara.

Euron aligned himself with Queen Cersei I Lannister while Yara aligned with Daenerys Targaryen, eventually leading to Yara retaking the Iron Islands and Euron going into exile in the Free Cities. Despite initially wanting to uphold her father's push for independence, Yara ultimately remained loyal to King's Landing and abdicated her royal titles in the aftermath of the Great War. The conflict between Yara and Euron remained unresolved until the War of the Narrow Sea, which saw Euron killed and the Ironborn fully reunited behind Yara.

House Greyjoy's sigil is a golden kraken on a black field, and their House words are "We Do Not Sow", although their more common saying is "What Is Dead May Never Die".
