On the surface, Game of Thrones seems like it's about noble houses manipulating each other, but peering closer reveals the real story — the control and domination of the common folk of Westeros, none of whom have a say in the leaders they get. Samwell Tarly attempts to democratize the political regime in the series finale but is cruelly shot down.
On the other hand, having a story about random people with no stakes wouldn't be as interesting as one revolving around those with resources, be it finances, family, or plain force. Taking only the first one into , here is a list of the wealthiest people to populate this fantasy world.
Doran Martell
The kingdom of Dorne is known for its martial strength and unbowed nature, only combining with Westeros through the marriage of one of its royal .
In addition, the area is known for its unique products and marine accessibility, which greatly promotes trade with other kingdoms as well as the continent of Essos, which is quite nearby. Therefore, it can be assumed that its ruler, Doran Martell, would have been fabulously rich, even if not as much as the others mentioned below.
Robert Baratheon
As the officially acknowledged ruler of Westeros, Robert Baratheon has control over all the coffers and treasuries of the seven kingdoms, although most of them were actually filled with tax money.
In any case, he clearly isn't poor or even middle-class, especially with the number of feasts and jousting tournaments he has the habit of throwing every now and then. The Baratheon family themselves are also well-to-do, as can be seen from Renly and Stannis' expenditure on both military and merrymaking.
Ramsay Bolton
As one of the most ancient Houses on the continent, the Boltons have an incredibly complex history and tradition (with most of them, unfortunately, revolving around various kinds of torture methods.)
Until they hand over dominion to the Starks, they were a terrible force in the North, although not much changed since that time. When Ramsay usurps the title by ending his father and infant half-sibling, he gains absolute authority over his bannermen, which increases further after his gruesome conquest of Winterfell.
Petyr Baelish
Littlefinger may have been born with little to his name, but the manner in which he schemes and claws into various noble families is a credit to his evil genius. Under Robert Baratheon, he held the coveted title of Master of Coin, which obviously suggests that he must have secreted a decent amount of gold into his own private s.
Not to mention the sheer power of his name in the brothel industry, owning some of the busiest "outlets" in King's Landing. Finally, his manipulating of Lysa Arryn raises his economic strength with the Vale behind him.
Sansa Stark
The Queen in the North has been given control of large swathes of land, incorporating several vassal houses, such as the Reeds, the Karstarks, the Cerwyns, the Pooles, and many more. In addition, she obtains the allegiance of House Bolton after its last ruler is justifiably massacred, adding to the affluence of House Stark.
Ned Stark always taught his children to behave with honor and common sense, which is why he rarely comes off as the stereotypical arrogant rich guy, but there is no doubt about this fact. How else would a Valyrian steel sword be his weapon of choice?
Mace Tyrell
The Tyrell household is known for their prosperity, amassed via its mini-empire encoming the Reach: the agricultural hub of Westeros, providing the remaining kingdoms with cereal crops, farm animals, alcohol, as well as orchard fruit.
In fact, it has been established that this region is more "upscale" than the Lannister Westerlands, given that the latter's legendary precious metals have depleted over time. Regardless, Lord Mace Tyrell is not richer than Tywin Lannister, but with the properties and tradable materials at his disposal, he is rather loaded.
Lord Bronn
At the end of the story, Bronn is given the same honors held by Mace Tyrell — Lord of Highgarden and Lord Paramount of the Reach, which should place him on par with the deceased head of House Tyrell. However, the Reach had been devastated by constant war and only regains some semblance of stability after the coronation of King Bran.
Without Lannister armies putting a stop to the region's commerce, Bronn will likely become wealthier than his "predecessor." Also, he's the new Master of Coin, but this doesn't necessarily imply anything.
Daenerys Targaryen
Daenerys has gone from rags to riches so many times that she herself has probably lost count. As a Targaryen princess, she would have had an opulent childhood but loses it all when her father is killed. However, when she hatches Drogon, Rhaegal, and Viserion, the tides begin to shift in her favor.
Controlling Meereen makes her one of the richest people in the world, but this is evidently not enough for her. When she leaves Essos for her homeland, Daenerys has multiple forces under her command, from the Dothraki army to the Unsullied (which means that she has enough cash to take care of their needs as well.)
Cersei Lannister
This family has always been swimming in money, right from the time Lann the Clever bamboozles House Casterly into parting with their prosperity. Cersei inherits a decent amount of this wealth when her father dies, but her spendthrift ways almost bankrupts her, forcing her to take a loan from the Iron Bank of Essos.
Still, she is number two on this list because of her sheer cunning, and also because she crowns herself the Queen of Westeros after the death of her son, which helps recoup many of her losses.
Tywin Lannister
Tywin Lannister, as the patriarch, has access to all of this wealth and uses it prudently to expand the influence of his house. Unlike everyone else mentioned here, he is the only one who truly knows how to spend money without wasting it, as well as investing in smart choices that strengthened his control over the continent.
Interestingly, Tywin is so skilled at this artform that many people joked that he probably used to "s**t gold"-- a fact disproven upon his death.
