Sojourner Truth (1797-1883), abolitionist, preacher and women’s rights lecturer, was born an African-American slave to the Colonel Johannes Hardenbergh estate in Ulster County, New York. After having been sold several times, Sojourner, whose birth name was Isabella Baumfree, was emancipated in 1827.
After several years as a domestic servant, Sojourner had a vision to travel through the U.S. spreading the abolitionist message while preaching repentance to those who were in agreement with slavery. She met with President Abraham Lincoln during the war and helped protect and educate freed slaves after the war.
