Elizabeth Cady Stanton concentrated her efforts on abolishing slavery during the civil war. She became involved in the abolitionist movement after a progressive upbringing.
I read her diary! Her role was she wrote the “Declaration of Sentiments” that called for equal rights for women and began pushing more loudly for suffrage for women.
In my view the best word would be ethos. Ethos is the set of fundamental values, guiding principles, social practices and beliefs that constitute the character of a particular culture.
