House Hoare

House Greyjoy is a former Great Houses of Westeros, which was ruling the Iron Islands when Aegon I Targaryen invaded the Seven Kingdoms.

Background
Three generations before the Targaryen Conquest, Harren's grandfather had conquered the Riverlands from the Stormlands, which had conquered the Riverlands some three centuries before Aegon's landing. The leaders of House Hoare ruled as Kings of the Iron Islands and the Riverlands.

King Harren intended to build the greatest castle on the entire continent, Harrenhal, on the north shore of Gods Eye lake in the Riverlands. It was completed on the same day that Aegon Targaryen set foot in Westeros. Harren was very cruel and arrogant, thus many of his vassals in the Riverlands - led by House Tully - rebelled against him and sided with Aegon Targaryen's invading force. The high walls of Harrenhal could have repelled any attack from the ground, but Aegon's dragons flew right over them. Dragonfire roasted King Harren alive within his own tower, along with all of his sons, rendering House Hoare extinct.

Following the extinction of House Hoare, the ironborn elected a new house to rule over them, under the overall rule of the Targaryen Kings on the Iron Throne: House Greyjoy.
