The fact that her black physical traits were visible in those paintings was, in itself, noteworthy, because it was customary at the time for artists to "play down, soften or even obliterate undesirable features in a subjects' face," also according to PBS. Even more controversial is the fact that the artist who depicted Queen Charlotte in all of her portraits was Sir Allan Ramsay , an anti-slavery advocate who went on to marry a black woman himself. All that being said, many historians believe the mere existence of Queen Charlotte and these portraits could have played a major role in the slavery abolition movement of the time. And that makes total sense. I mean, think about it: As we saw on The Crown , Queen Elizabeth II wouldn't even allow her sister to marry a man who had once been divorced. And that was in the 1950s. Can you imagine the existence of a black queen back in the 18th century?!
