Answer:
Harriet Tubman was a nurse, a union spy, and a woman's suffrage supporter. She became a conductor for the underground railroad bringing enslaved people to freedom all while having a bounty on her head.
The oldest of eight children, Ida B. Wells was born in Holly Springs, Mississippi. Her parents, who were very active in the Republican Party during Reconstruction, died in a yellow fever epidemic in the late 1870s. Wells attended Rust College and then became a teacher in Memphis, Tennessee. Shortly after she arrived, Wells was involved in an altercation with a white conductor while riding the railroad. She had purchased a first-class ticket, and was seated in the ladies car when the conductor ordered her to sit in the Jim Crow (i.e. black) section, which did not offer first-class accommodations. She refused and when the conductor tried to remove her, she "fastened her teeth on the back of his hand." Wells was ejected from the train, and she sued. She won her case in a lower court, but the decision was reversed in an appeals court.
Because there would be more trade which will benefit the merchant.
Yes it would have because if Virginia had rejected secession, the prospect of Lee in command of Union forces rather than Confederate forces would have presented major problems for the Confederacy. The South would have lost a major economic and political asset, the state of West Virginia would never have been created, the war would almost certainly have been shorter. Interestingly, such circumstances might cast some doubts on how determined the North would have been to end slavery permanently.
Hope this helped!!
