D. Soujourner Truth. Sojourner Truth was an African-American abolitionist and women's rights activist. She was the first black woman to win a case in court against a white man. During the Civil War, she helped recruit black troops for the Union Army. Her historic speech for women's rights "Ain't I a Woman" became very famous and she continued to make very famous lectures and speeches across the country. She also was against prison reform and capital punishment and spoke to Ulysses S. Grant, the current president, about it.
I'm interested in this question myself, I don't think Indians ever left physical structures behind, so I looked up a ton on geographical features left behind by Indians and not just in Northeastern and Southeastern America, because there are many types of Indians, but nothing came up on any type of Indian especially in the 1500's. I tried, but I don't think this question can be answered, I looked up this question in many different ways and broke it down to try and gather small pieces of information, but in the end there was no features known to be left behind by American Indians. If anything they left behind culture and methods of doing things. Hope anything I said helps even though I could not figure out the answer.
