The year 2020 marked a century since American women won the right to vote. In a new book titled “Formidable: American Women and the Fight for Equality: 1920-2020,” historian Elisabeth Griffith traces what happened next, after the the ratification of the 19th Amendment. She recounts how women exercised their political power and pushed for change.

Griffith’s chronology highlights battles over voting rights, working conditions, education access, health care, reproductive rights, gender discrimination and the wage gap.

In laying out this history, she tells a complex story of progress and setbacks, victories and defeats as American women struggled to unite and work toward an inclusive path that would lead to fair treatment for all.
