Sojourner Truth was born into slavery in the late 18th century in New York and experienced a difficult childhood being sold several times. She escaped slavery with her daughter and advocated for the abolition of slavery and women's rights. Her most famous speech "Ain't I a Woman" was delivered in 1851 at the Ohio Women's Rights Convention, where she powerfully argued that women deserved equal rights and challenged the notion that women were weak and subordinate. Sojourner Truth spent her life fighting for the rights of both slaves and women and became a renowned speaker on these issues until her death in 1883.
