She was 29 years old, and a slave. She'd never been to school and could not read or write. She had been beaten, abused, and humiliated. Except for the few square miles around her home, she knew nothing of the outside world. One spring evening in 1849, she boldly entered into a world she had never seen, in search of a place she'd never been, hoping to find something she'd never known: freedom. Her name was Harriet Tubman and her nickname was Moses.
