The Women's March was a worldwide protest movement in response to the 2016 presidential election when Donald Trump defeated Hillary Clinton, the first woman to be nominated for president by a major political party in the United States. Teresa Shook, a Hawaii resident, was widely credited with originating the idea of the march after creating an event on social media and inviting her friends to march on Washington DC in protest of President Trump's inauguration. As more events were posted on social media and thousands of women began to respond, more experienced political organizers transformed the event into a multi-site protest with international reach. Many women knitted "pussy hats," bright pink caps with two points that resembled cat ears, to wear in the cold, January marches. According to the pattern's designers, Jayna Zweiman and Krista Suh, the hat's name "was chosen in part as a protest against vulgar comments Donald Trump made about the freedom he felt to grab women's genitals, to de-stigmatize the word "pussy" and transform it into one of empowerment, and to highlight the design of the hat's 'pussycat ears'." On January 21, 2017 over 200,000 attended the Women’s March in Washington DC. An estimated 3 to 5 million people marched in over 600 locations in the United States and around the world. Smaller Women’s Marches were held in subsequent years.
