The March4Women rally came ahead of International Women's Day on Thursday, with crowds demanding an end to unequal pay.
Thousands of people have taken part in a march in London to highlight the fight for gender equality.
The rally coincided with the 100th anniversary of some women being given the right to vote.
Celebrities including Bianca Jagger, Anne-Marie Duff, Natalie Imbruglia, Biffy Clyro and Michael Sheen joined London's mayor Sadiq Khan on the march.
Helen Pankhurst, the great-granddaughter of suffragette Emmeline Pankhurst, also attended and said "right across the board, in every sphere, there's work to be done".
She added: "I think we are living in a world where there are some dinosaurs that are trying to take us back.
"And there are those that are moving together, trying to say 'that's not the way we want this world to look', and moving us forward, and looking at issues around inequality and naming prejudice and all sorts of forms of entitlement, that just shouldn't be part of the scene of the 21st century."
Ms Pankhurst said there was a "great energy" and that "day after day after day there's a media story saying we are not going to tolerate this anymore".
