Who was the United States abolitionist and feminist that advocated for both the abolition of slavery and women's rights, living from 1797-1883?

The individual described in the question is indeed Sojourner Truth. She was a prominent figure in both the abolitionist movement, which sought to end slavery in the United States, and the women's rights movement, advocating for gender equality. Sojourner Truth was born in 1797 and lived until 1883, making her a key activist during a transformative period in American history.

Truth is renowned for her powerful speeches and advocacy, most famously delivering the "Ain't I a Woman?" speech at the 1851 Women's Rights Convention in Akron, Ohio. This speech eloquently addressed the intersection of race and gender, highlighting the experiences of Black women in a society that marginalized both their racial and gender identities.

Her work not only contributed to the fight against slavery but also laid foundational principles for the women's rights movement, making her a critical figure in advocating for social justice on multiple fronts. This dual commitment to abolition and women's rights distinctly marks her contributions in history, setting her apart from other activists who may have focused predominantly on one cause.
