Wars of Conquest

From Asoiaf

The Wars of Conquest were the wars fought by Aegon the Conquerer to unite the Seven Kingdoms.

Orys Baratheon, rumored to be Aegon's bastard brother, defeated Argilac the Arrogant, tbe last Storm King. As reward Aegon granted him Argilac's castle, lands and daughter.

Harren the Black, King of the Isles also ruled the riverlands, however he was not well loved and many of the river lords deserted him, first amongst them Edmyn Tully, Lord of Riverrun. Harren and his line perished in the burning of Harrenhal. Afterwards Aegon granted Edmyn Tully dominion of the lands of the Trident.

The last King in the North, Torrhen Stark, the King Who Knelt, chose to swear fealty to Aegon the Dragon rather than do battle. He therefore kept his land and continued to rule as Lord of Winterfell.
