Today sees the Women's March on Washington, potentially the biggest inauguration-related protest in history.
The movement began with just a single Facebook page after the election of Donald Trump, and grew into a force to be reckoned with.
An expected quarter of a million protestors will march on Washington D.C. today - but that's not all...
Altogether more than a million people around the world in over 60 countries, from Australia to Antarctica, are participating in so-called Sister Marches, showing global solidarity and campaigning for gender equality in their own countries.
They will march for human rights, for women's rights, immigration rights, abortion / reproductive rights and equality.
They march against hate, sexism, gender violence, misogyny, institutionalised patriarchy, racism, Islamophobia, transphobia and homophobia.
Don't be fooled - it's not a straightforward anti-Trump protest.
Rather, the Women's March is harnessing the outrage provoked by Trump's more disgraceful misogyny and anti-minority rhetoric to unleash a global wave of female empowerment, and to show a united international stand for human rights.
The Independent will be running a liveblog of global events all day as the marches unfold, but let's have a look at some incredible scenes so far...
Flights to Washington D.C. from all over America are filled with marchers.
