One day after President Donald Trump's inaugural parade wound its way through the District of Columbia, hundreds of thousands of women poured into the city from across the country, carrying signs, pink knitted hats and an overwhelming sense of rage and grief.

The first Women's March – an alliance of hundreds of nationwide marches widely considered the largest single-day protest in American history –funnelled feelings into action. Women who had never carried a sign became seasoned protesters. Strangers formed letter-writing campaigns and action networks. It was, experts said, the moment the "resistance" was born.
