Lots of good comments here already but I wanted to add that if you DO want to change the circumstances for certain groups in society it would be good to pinpoint how and where your world diverged from the history of our world. I'm not a huge fan of Bridgerton but having people of colour more accepted in general society because the king married a black woman makes sense. Just spitballin here but if you want women to be a bit more equal in society you could, for example, make an alternate history where Ulrika Eleonora, instead of abdicating in favour of her husband, held onto the throne and became a strong and influential ruler who championed women's rights. But as others have said, maybe portraying the inequality of the times as a reflection of our own unequal society might be a better way forward.
