Inspired by the Women's March on Washington, people in cities around the world hit the streets on Saturday to show solidarity with Americans and to promote human rights and gender equality in their own countries.
While the march in Washington was forecast to draw about 200,000 people, organizers said other marches dotted around the United States – and indeed the world – could collectively draw crowds 10 times that figure. Organizers said they want to send a bold message to President Donald Trump on his first full day in office that women's rights are worth defending.
Trump's campaign was colored by sexist remarks, allegations of sexual assault and lewd comments about women that Trump dismissed as "locker room talk." Many women voted for Trump, including the majority of white women.
Some organizers have tried to play down the marches as "anti-Trump" and instead emphasize messages of unity.
"It's an opportunity to come together, to grieve and then to turn that around to celebrate unity," said Kimberly Espinal, one of the organizers of the London rally that kicked off at noon local time.
On a cold and sunny winter's day, the crowd in London was large and lively. Demonstrators held colorful placards reading "Our voices together can't be silenced" and, in apparent reference to Trump, "Even Voldemort was better."
