What makes Sarah unique and interesting as a 19th century character is that she displayed awareness that she is a strong and intelligent woman. Towards the end of the story, she had described herself aptly to Mr. Hersey, stating: "...there are things people hadn't ought to interfere with...I've got my own mind an' my own feet, an' I'm goin' to think my own thoughts an' go my own ways, an' nobody but the Lord is goin' to dictate me unless I've mind to have him."

This passage from the story demonstrated that what made Sarah successful in her 'revolt' against her community's discrimination was the fact that she fought to defy social conventions dictating women to not have 'their own minds' when arguing with men. Furthermore, her resistance to the norms of her society...

In fact, this bold move made Adoniram realize his narrow-mindedness, thinking only of his needs rather than his family's.
In effect, Sarah's character in "Revolt" illustrated a woman who was able to transcend the limits her society had put upon her by expressing her feelings and acting not for other people, but for her and her family's welfare only, which, as it turned out, became the right thing to do for her.
