Recovering the powerful and influential contributions of women from the nation's formative years. This work traces the significance of Frances Wright, Harriet Martineau, Angelina and Lucretia Mott, Elizabeth Cady Stanton, and Sojourner Truth in shaping American political thinking. These women understood the relationship between sexism, racism, and economic inequality; yet, they are virtually unknown in American political thought because they are considered activists, not theorists. Their efforts to expand the reach of America's founding ideals laid the groundwork not only for women's suffrage and the abolition of slavery, but for the broader expansion of civil, political, and human rights that would characterize much of the twentieth century and continues to unfold today.
