House Baratheon is the ruling royal house when "Game of Thrones" begins, but it's not nearly as strong or important during the "House of the Dragon" era. In fact, the house's origins are actually depicted in the book "Fire and Blood." The book covers several generations of Targaryen rule, starting with the conquest of Westeros by Aegon I. House Baratheon is founded by Orys Baratheon, one of Aegon I's generals, when he marries the last heiress of a conquered house.
Boremund Baratheon is seen in the first episode of "House of the Dragon" also pledging his support to Rhaenyra.
