Part 1: Why is Nettles black?
TLDR: George subverts a bunch of stereotypes specifically tied to black women in media with Nettles, she's black, innocent, not practising magic, young, doesn't nurture or take care of anyone and her own sexual experiences aren't exploited in her narrative rather in a projection of someone. The closest she comes to any other race is when they call her a dragon lady at the end, which is an Asian stereotype but not something invoked to critique. Nettles is black.
So I said it before, but now again, this is a two part post because when it comes to this character, I think the relevance of her race is often lost because of what is percieved as a greater narrative purpose. But Nettles race and specifically her being black is important to her story. The next part will delve into her role in the narrative as a black girl, but this part is generally why I can say she's black with confidence using the written narrative.
There are multiple stereotypes used to box black women in specifically from the inception of race in media. Some of the most prominent are the (in great reduction to the nuance):
Sapphire: angry, loud, and rude black woman
Jezabel: sex driven, lust bound, and seductive black woman
Mammy: nurturing, sexless and typcially bigger black woman.
Magical black woman: linked to some sort of witchcraft practice but not central to the narrative. Not to be confused with the magical negros trope which is different.
Tragic Mulatto: mixed raced stereotype that they belong no where.
Ghetto: I saw this recently, but this is basically the hood girl trope.
Grown black girl: this is when they treat black girls as older than they are, like adults when they are kids.
These concepts have smaller sub tropes, and there are more stereotypes, but even to this extent, there is a battle with media literacy when it comes to the way people see black female characters in media.
For the sake of Nettles, we'll be covering all in the next part. Along with the history, seeing as most if not all the origins for these tropes can be found in Slavery.
With the sapphire trope, George manages to give Nettles these characteristics and add on to them, so while they are a part of her character, there is depth and nuance. She is rude, called foul-mouthed in the narrative, but she is also fearless and smart. She never gets angry in the written narrative, but she does cry and mourn and show an emotional intelligence we don't get from all her peers. She defies the expectation of a rude, lowborn character being crass, lusty or power hungry, and jealous alone.
The Jezabel story is a perverse fantasy. A black woman is solely driven by lust and desire, nothing more than a sexual object. It's a trope that actively harms young black girls as well. So, in the books, whether or not you believe Nettles has sex, she isn't solely there for it. She isn't just there to have sex with Daemon, and when it is brought up, the men around her prioritise the innocence of her youth rather than the treason she is said to commit.
Nettles doesn't really fit the many trope as she is younger than the trope typically allows for but within the narrative of all the connections we could've gotten we got one with a Prince rather than with children to communicate the fact that she loves but she isn't a care taker.
The magical black woman stereotype or black witch stereotype is rooted in the both spirituality and abuse. White women would use both the Jezabel stereotype and this one to claim that the reason their husbands would sleep with the enslaved women of the plantation were because they were sexually deviant seductresses who ensnared the men basically.
This is the clearest stereotype George both evokes and subverts. He purposefully wrote that in to draw a real world parallel and subverting it in his book.
Lastly, the tragic mulatto stereotype is the trope of two white for the black side to black for the white side. Basically, they are sad because they have nowhere to belong. Interestingly, George doesn't use this at all. Which to me was an indicator that Nettles doesn't have this complex. All the people of colour, especially the brown skinned ones, have a complex relationship with the Valyrians, but Nettles doesn't.
This isn't really an exception, but more so a name he uses that is tied to a trope. Nettles is called a dragon lady out of context of the stereotypes in the books. The reason I brought it up was because a lot of people seem to think Nettles could be any kind of brown in the narrative, which isn't exactly correct. The dragon lady stereotype is tied to many Asain women, but the content of it isn't tied to Nettles past the name.
I think we have moved past the need for the Ghetto trope. It's basically someone who grew up in an urban, low income area and whose behaviour represents the culture there. I don't think Nettles is a victim of Reaganomics so I don't think she's affected by this.
Nettles is also purposefully treated as a young lady in the narrative. She's the Westeros equivalent of 18 and is treated by the men of her narrative as a girl. She's called a child, said to be innocent and freed from her sentence because of it. The exception to this is with Daemon Targaryen, who sexualises her narrative, but it isn't meant to be explotative AS IT IS WRITTEN. It's presented as love.
George uses black women stereotypes and tropes in media and subverts them with Nettles. He specifically uses her appearance to justify it and allows him to communicate with race without saying it out loud. Nettles is a black character written in a story where she can defy the media conventions of her identity. She is back for a reason and none at all.
