Gr 2–4—Elizabeth Freeman, known as "Mumbet," was an African American slave in 18th-century Massachusetts. The Massachusetts Constitution of 1780 included the provision, "All men are born free and equal, and have certain natural, essential, and unalienable rights." Using that document as a basis, Mumbet, with the support of a young lawyer named Theodore Sedgwick, challenged the legality of slavery. As a result of their efforts, in 1783 slavery was declared unconstitutional and 5000 slaves in the state gained freedom. Vividly colored illustrations reflect the generally hopeful tone of the story, while bold compositions and thickly layered paint suggest folk art. Freeman's strength of character is reflected in her determined facial expressions and strong stance. While her story is highly inspiring, details about her life are sketchy; information comes primarily from an account written by Catharine Maria Sedgwick, the daughter of Theodore. While this picture book is presented as nonfiction, the story itself is highly fictionalized. An author's note explains what is known about Mumbet and reminds readers that "History is fluid."—Lucinda Snyder Whitehurst, St. Christopher's School, Richmond, VA
