But after Tommen committed suicide following the Destruction of the Great Sept of Baelor, Cersei Lannister assumed the throne as Westeros’ first reigning queen and House Lannister became the most powerful region in Westeros at last. House Baratheon ruled the next two decades until King Robert died in a “boar hunting accident.” After that, King Joffery and King Tommen ruled but they’re basically Lannisters. Anyway, for most of 3 centuries, the Targaryens ruled the area and Westeros until Robert’s Rebellion overthrew them. So it’s no surprise that both areas seem culturally similar. Created by Aegon the Conqueror since it was where 3 of the major kingdoms met, the Crownlands are the newest region of Westeros since they were once part of the Riverlands. Yet, it also includes the Targaryen ancestral home of Dragonstone. A place of palace intrigue, it is home to the Iron Throne that so many are willing to kill for. As the capital region of Westeros, the Crownlands is a prevalent setting in Game of Thrones, particularly if It’s King’s Landing.
