Donald Trump's surprise victory necessitated a rethinking of narratives of both self and nation, and a reimagining of the future for many feminists and others on the left. Misogyny and white nationalism, as we saw in parts 1 through 3, fueled Trump's campaign and victory; it is thus fitting that the election inspired a new, multiracial women's movement with a broad and inclusive social justice agenda. The planning of the Women's March to coincide with Trump's inauguration sparked a debate about the best methods to realize an intersectional feminism, a necessity that is dedicated to dismantling the many “systems of oppression” governing women's lives. On January 21, 2017, more than 5 million people worldwide participated in 635 reported marches in the United States and at least 261 marches abroad, in “what was likely the largest single-day demonstration in recorded U.S. history.” The Women's March was notable for the diversity of participants, who spanned generations and racial and ethnic groups, as well as for their numbers and geographic range.

Leading up to the 2016 election and in its aftermath, many of the marchers had participated in the online “intimate publics” described by Gina Masullo Chen and Kelsey Whipple in this volume; those social media groups as well as “huddles” inspired by the Women's March itself led to the formation of hundreds of new, community-based women's groups, which dedicated themselves to involvement in local government and encouraging women to run for office in an effort to transform the American political system from the ground up. In November 2017, a record number of women candidates and their grassroots supporters led the Democratic Party to a surprise upset in the Virginia House of Delegates, while Black women's high turnout and almost uniform support for Democrat Doug Jones proved decisive in Jones's December 2017 victory over Republican Roy Moore in the Alabama special election for the US Senate. A year after the first Women's March, on the weekend of January 21, 2018, hundreds of thousands of protestors again marched through cities across the United States and the world, including 300,000 in Chicago and 500,000 in Los Angeles.
