More specifically characters like John Laurens, Elizabeth Schuyler, and Hamilton himself (especially John, whose character’s main motivation seems to be liberating black slaves).
I’ve heard that there are numerous points in the play that aren’t entirely accurate to real life, such as how Philip Schuyler did actually have sons, something I could attribute to Lin’s desire to tell a certain story.
However I was wondering if these people really were as anti-slavery as the play described them as or if it was simply a more charitable portrayal of some not so nice people.
I've read a fair amount of pieces on how Hamilton missed some things historically or twisted them slightly, but Lauren's anti-slavery stance isn't one of them. He was raised in a wealth family and his dad owned a slave trade business, yet he still was very against it in his adulthood. I found this little biography that's pretty cool.
