The influential women's rights activist best known for her public speeches is Sojourner Truth. A former slave, Truth became a powerful advocate for abolition and women's rights. Her most famous speech, "Ain't I a Woman?" delivered in 1851 at the Women's Rights Convention in Akron, Ohio, challenged prevailing notions of gender and race. Through her eloquent and impassioned oratory, Truth highlighted the intersectionality of oppression, emphasizing the need for women, especially black women, to have equal rights. Her legacy continues to inspire advocates for social justice today.
