At the end of the American Revolution, Elizabeth Freeman was an enslaved widow and mother living in Massachusetts. Hearing the words of the new Massachusetts state constitution which declared liberty and equality for all, she sought the help of a young lawyer named Theodore Sedgwick, later Speaker of the House and one of America's leading Federalist politicians.

The lawsuit that she and Sedgwick pursued would bring freedom to her and her daughter, as well as thousands of other enslaved people. After leaving her enslaver's family to work for the family of Theodore Sedgwick, she effectively became the foster mother to his seven children when his wife Pamela became a chronic invalid, enabling Sedgwick to pursue his political career.

Two of his sons would credit her with saving their lives. His daughter Catharine Maria Sedgwick, one of the most famous female novelists of the early decades of the nineteenth century, would make her the model for one of her most celebrated heroines.

This biography details Elizabeth Freeman's life and the far-reaching influence of her battle for freedom. .
