"Ours is the Fury"
The House of Baratheon was founded after the conquest of Aegon Targaryen by the conqueror's general (and rumored bastard brother) Orys Baratheon. More recently, following Robert's Rebellion, the Baratheons of Storm's End seized the Iron Throne from the Mad King Aerys Targaryen and have ruled the Seven Kingdoms since.
