Close to 700 marches have been held around the world, with organisers estimating more than 4.5 million people have taken part.
Thanks to the international dateline, New Zealand was the first to rally, complete with reminders of New Zealand's place in the history of political representation for women.

Social media - and streets - struggled to contain the marchers.

And, of course, politicians got in on the act.
Thanks for standing, speaking & marching for our values @womensmarch. Important as ever. I truly believe we're always Stronger Together.

This is a good question.
Somebody write an analysis of how social media has made protestors' signs wittier in general
— annkpowers (@annkpowers) January 21, 2017
But the question that many are asking now, is... what next?
Stop asking if the #WomensMarch 'will achieve anything in the long run.' It already has. Millions of women feel less beaten today.
