Westeros in House of the Dragon and Game of Thrones is divided up into the Seven Kingdoms, but there are really nine of them – here’s why.

Game of Thrones’ Seven Kingdoms make up a huge part of the show and its spinoff series, House of the Dragon, but why is this the case when there are really nine of them? Given that this is where House of the Dragon and Game of Thrones spend the vast majority of their time and that numerous characters refer to “the Seven Kingdoms,” it’s surprising that the shows never explain this odd little piece of nomenclature.

Finding the genesis of the Seven Kingdoms involves going back to the time of Aegon’s Conquest, which happens before House of the Dragon‘s Targaryen civil war, and around 300 years before the events of Game of Thrones. When Aegon Targaryen landed at Blackwater Rush with his sister-wives, Rhaenys and Visenya, it was part of a Westeros that was divided into seven separate realms:

• The North: ruled by Torrhen Stark.
• The Mountain & the Vale: ruled by Ronnel Arryn.
• The Isles & the Rivers: ruled by Harren Hoare.
• The Rock: ruled by Loren Lannister.
• The Reach: ruled by Mern Gardener IX.
• The Stormlands: ruled by Argilac Durrandon.
• Dorne: ruled by Princess Meria Martell.

The Seven Kingdoms

House of the Dragon‘s Seven Kingdoms feature vastly different landscapes and political practices, despite being ruled under one head. The North, led by House Stark, was one of the main locations shown in GOT, along with King’s Landing but the Tyrell’s Highgarden wasn’t really seen. However, it was described as a beautiful place filled with flowers. The mountainous Vale had an interesting form of punishment for their prisoners, in the form of a gate on the floor that would force their inmates to fall to their deaths. Dorne is a mixture of desert and tropics, featuring a rather standard-looking prison.

Meanwhile, Casterly Rock was only seen a handful of times in Game of Thrones, House Tully’s Riverlands were featured in several episodes too. A stark contrast to these is the Iron Islands, which are dark and stormy, a perfect complement to the dangerous seas surrounding them. The rest of Westeros remained largely unexplored in GOT and House of the Dragon hasn’t really changed that.

How Game Of Thrones’ 7 Kingdoms Became 9 Realms: The Full History

The Seven Kingdoms were the seven lands that Aegon set out to conquer and unite before House of the Dragon, which he mostly did over the course of the next two years, bringing them together under the rule of House Targaryen and the Iron Throne. When Aegon was eventually crowned at the Starry Sept in Oldtown, he was proclaimed ‘Lord of the Seven Kingdoms,’ although it wasn’t entirely true even then. The Dornish resisted Aegon’s attempts to conquer them by hiding out in the Mountains and engaging in guerilla warfare, and Princess Meria refused to yield.

It wasn’t until 187 years after Aegon’s Conquest that Dorne officially joined the Seven Kingdoms thanks to a peaceful marriage pact between Prince Maron Martell (the ruler of Dorne at the time) and Princess Daenerys Targaryen (not that one), the younger sister of King Daeron II Targaryen, thus finally making the realm whole. However, this was actually turning Game of Thrones‘ Seven Kingdoms into nine, because Aegon had long since made some big changes to his newfound empire.

The Riverlands, which had long ago been independent, were ruled by House Hoare during Aegon’s Conquest. However, as a reward for supporting the Targaryens against the Hoares, the Kingdom of Rivers & Isles was split into two: House Tully was granted lordship over the Riverlands. At the same time, House Greyjoy assumed control of the Iron Islands. That made it into Eight Kingdoms, while Aegon Targaryen also decided to make King’s Landing and the surrounding area into a principality of its own, known as the Crownlands, which was loyal solely to the crown. Because of their service during the Conquest, command of the Reach passed to House Tyrell, while House Baratheon was granted the Stormlands. Therefore, House of the Dragon should feature all nine kingdoms at some point, considering it takes place at the beginning of the end of the Targaryen reign and the book includes the majority of them.

The Current 9 Realms Of Westeros

So, the Seven (or nine) official Kingdoms of Game of Thrones and House of the Dragon are made up as follows:

• The North – House Stark
• The Vale – House Arryn
• The Iron Islands – House Greyjoy
• The Riverlands – House Tully
• The Westerlands – House Lannister
• The Stormlands – House Baratheon
• The Reach – House Tyrell
• The Crownlands – House Targaryen
• Dorne – House Martell

If that looks familiar, it’s because it’s a status quo that existed from the events of House of the Dragon until Robert’s Rebellion. At this point, the Baratheons took the crown, and then further changes were made following Game of Thrones‘ War of the Five Kings. The Seven Kingdoms as people know them were established with Aegon’s conquest, or when Dorne officially joined and remained so throughout the entire run of Game of Thrones until the finale.

Will House Of The Dragon Season 2 Show New Parts Of The Seven Kingdoms?

The Game of Thrones prequel series House of the Dragon has branched out its filming locations, which allowed the in-story world to expand. The TV show kicked off with the seeds being planted for the Targaryen civil war, so most of the series focused on King’s Landing. The show also included several characters from places like Oldtown and Dorne but they haven’t been seen all that much. House of the Dragon did expand to show the Steptones and even Storm’s End.

Based on the Fire & Blood book the story is adapted from, even more places can be explored in future seasons. For example, Jacaerys Velaryon visits Winterfell though that has been seen a lot in Game of Thrones. There’s also the chance for further looks at the Reach, the Iron Islands, the Vale, and more given the places where characters visit in the books and who gets involved in the “Dance of the Dragons.”
