As many as 500,000 people gathered for the Women's March on Washington on Saturday, the centerpiece of marches in an estimated 600 cities, according to the Associated Press. Advocating for women's rights, the message of the marches was distinctly against President Donald Trump, who made several controversial sexist remarks over the course of his presidential campaign.

Metro ridership numbers from WMATA indicated that it's probable that more people traveled to Washington, D.C., for the women's march than for Trump's inauguration on Friday.

Saturday's march was relatively peaceful compared to aggressive protests during Trump's inauguration on Friday.

"It's incredible unity here. The numbers here are as high as I would've expected and imagined and I'm not seeing any animosity," said Julie Gelfand from Rochester, New York. "I was here yesterday and there were a lot of differences of opinion and types of people and here there's diversity but everybody's coming from the same place.

"A lot of the times when you think about women's problems, they're addressed as just women's problems or black's problems or hispanic's problems, but I think here we're showing that there are women in all of those categories and we're coming together as one. We're all women no matter what background we're from," said Laura Ribero, who traveled from Maryland.

The main events on Saturday took place on Independence Avenue SW, near the National Museum of the American Indian. Speakers included Gloria Steinem, National Resources Defense Council President Rhea Suh, and celebrities like Scarlett Johansson and America Ferrera.
