When Aegon Targaryen landed on the shores of Westeros with his dragon army, the continent wasn't a single nation. It was a patchwork of warring sovereign states, distinct cultures, and shifting borders. The phrase Seven Kingdoms of Westeros refers to the political entities that existed prior to the Targaryen conquest, even though the unified realm eventually came to encompass nine distinct administrative regions. Understanding how these territories functioned requires looking past the map and examining the individual histories, ruling families, and geographical advantages that shaped George R.R. Martin's fantasy world.
The geopolitical landscape of Westeros is defined by natural barriers, resource distribution, and centuries of intermittent warfare. While the Iron Throne eventually bound these lands under a single monarch in King's Landing, the regional identities of the Great Houses remained fiercely independent.
The Historic Seven Kingdoms Before the Conquest
Before Aegon I Targaryen united the continent, Westeros was divided into distinct sovereign realms. The number seven stuck in the cultural lexicon because of the dominance of the Faith of the Seven and the historical treaty of the six kingdoms that bent the knee, alongside Dorne which joined much later through marriage.
- The Kingdom of the North: Ruled by House Stark from Winterfell, this vast, cold territory covered roughly a third of the continent. The Northmen practiced the old ways and worshipped the old gods.
- The Kingdom of the Isles and the Rivers: A dual territory controlled by House Hoare. The Ironborn of the Iron Islands ruled over both their rugged maritime rocks and the fertile Riverlands until Aegon's invasion.
- The Kingdom of the Mountain and Vale: Governed by House Arryn from the impregnable Eyrie, this mountainous region protected itself through altitude and narrow, easily defended mountain passes.
- The Kingdom of the Rock: Ruled by House Lannister from Casterly Rock, famous for immense mineral wealth generated by gold mines that fueled their military power.
- The Storm Kingdom: Controlled by House Durrandon from Storm's End, a windswept southern coast frequently battered by punishing seasonal tempests.
- The Kingdom of the Reach: Ruled by House Gardener from Highgarden, boasting the most fertile agricultural land and largest populations on the continent.
- The Principality of Dorne: Ruled by House Martell from Sunspear, an arid southern desert region that resisted Targaryen conquest for centuries through guerrilla warfare.
The Nine Modern Administrative Regions
When people talk about the geography of Game of Thrones and House of the Dragon, they usually reference the nine administrative regions established after the Targaryen conquest. The old Kingdom of the Isles and Rivers was split, and the royal domain around the capital was carved out as its own entity.
The North and House Stark
The North is harsh, sparsely populated, and bound by harsh winters. House Stark acts as the traditional Warden of the North, maintaining order from Winterfell. Their cultural isolation and adherence to the old gods keep them distinct from southern politics. Strategic choke points like Moat Cailin make a northern invasion nearly impossible from the south.
The Riverlands and House Tully
Occupying the central river basin, the Riverlands lack natural borders, making them a perpetual theater of war. House Tully rules from Riverrun, but because the region is indefensible, it has frequently changed hands and suffered devastating losses during regional conflicts.
The Iron Islands and House Greyjoy
A cluster of barren, stormy rocks off the western coast, the Iron Islands are home to the Ironborn. Ruled by House Greyjoy from Pyke, their culture rejects traditional agrarian labor—encapsulated in their motto "We Do Not Sow"—in favor of raiding, seafaring, and maritime dominance.
The Westerlands and House Lannister
Home to the richest gold and silver deposits in Westeros, the Westerlands are governed by House Lannister from Casterly Rock. Their immense financial capital allows them to buy loyalty, fund massive armies, and exert outsized influence over the Iron Throne.
The Reach and House Tyrell
The agricultural engine of the continent, the Reach is characterized by rolling hills, warm weather, and abundant crops. Governed by House Tyrell from Highgarden, this region supplies food to the rest of Westeros and fields massive chivalric knightly orders.
The Stormlands and House Baratheon
Stretching south of Blackwater Bay, the Stormlands are rugged, forested, and prone to violent weather. House Baratheon rules from Storm's End, an ancient fortress built to withstand the fury of the narrow sea.
The Vale and House Arryn
Encircled by the towering Mountains of the Moon, the Vale is fertile in its internal basin but heavily fortified. House Arryn controls access through the Bloody Gate and rules from the Eyrie, a castle perched high on a stone pillar that makes ground assault futile.
Dorne and House Martell
Dorne is the southernmost and most exotic region, featuring deserts, mountains, and a distinct culture influenced by Rhoynar migration. House Martell rules from Sunspear. Dorne maintains unique laws regarding inheritance, passing titles to the eldest child regardless of gender, and resisted foreign subjugation longer than any other region.
The Crownlands
Directly surrounding King's Landing and Blackwater Bay, the Crownlands were never an independent kingdom. Instead, Aegon carved this territory out of the Riverlands and Stormlands to serve as the direct personal domain of the Targaryen monarchs and the seat of the Iron Throne.
Common Historical Misconceptions
- The Crownlands as a Kingdom: Many casual viewers assume there are seven kingdoms plus the capital region, but the Crownlands are a royal demesne. The original count of seven relies on pre-conquest sovereign boundaries.
- Dorne's Conquest: A common error is assuming Aegon conquered all seven territories. Dorne remained entirely independent during the initial invasion and only joined the realm centuries later through a political marriage alliance.
- The Iron Islands and Riverlands Unity: Before the Targaryens arrived, House Hoare ruled both the iron-rich islands and the mainland river basin as a single combined realm, which inflated the pre-conquest kingdom count.
Frequently Asked Questions
Why are they called the Seven Kingdoms if there are nine regions?
The name is a historical holdover. Before Aegon's Conquest, Westeros was divided into seven distinct sovereign realms. Even though the Targaryens split the Riverlands and Iron Islands and created the Crownlands, the traditional title stuck for political and cultural prestige.
Which kingdom was never conquered by Aegon?
Dorne was never conquered by Aegon I Targaryen. Using desert guerrilla tactics and avoiding open battlefield engagements, the Dornish resisted dragon warfare successfully. It officially joined the realm nearly two centuries later through a peaceful treaty and marriage.
Where does the Iron Throne get its authority?
The Iron Throne derives its supreme authority from King's Landing in the Crownlands. The monarch sitting on the throne holds feudal fealty from the Wardens and ruling Great Houses of the other major regions.
How did the Targaryens unite the continent?
Aegon I Targaryen used three dragons—Balerion, Vhagar, and Meraxes—alongside a small army to land at the mouth of the Blackwater Rush. By deploying air superiority against massed enemy formations, he forced the surviving regional kings to either submit or burn.
