This year's march takes place on International Women's Day.
Back in 2016, the world came together to protest the election of the 45th President of the United States, Donald Trump.
All over the world, millions of people took to the streets to stand in solidarity with women in America as they lambasted their first-in-command. Spanning from South America to Europe to Asia, the protest became one of the largest ones in history.
Today, the Women's March has evolved from not-so-humble beginnings into an international feminist movement that brings thousands of people together to fight the good fight for social change and gender equality.
When is it?
While marches took place internationally on Saturday 19 January, a representative from Women's March on Washington - Ireland has informed Irish Tatler that this year's Irish marches won't be taking place until International Women's Day, Friday 8 March.
Where does it start?
Everything kicks off at 3pm from O'Connell Bridge.
This year's theme for the march on 19 January is 'Stop Violence Against Women'.
And, it rings particularly poignantly in Ireland as, nine days into 2019, the bodies of two women made national news due to their violent deaths in Ireland.
The march is also calling for a number of issues regarding women's equality to be addressed, including ending gender-based violence and harassment, ending the gender pay gap, ending precarious conditions in work and housing, standing with the struggle for abortion rights in the North and standing in solidarity with struggles against oppression and workers’ struggles at home and abroad.
The theme for International Women's Day is #BalanceforBetter.
In the words of the International Women's Day website:
"The future is exciting. Let's build a gender-balanced world. Everyone has a part to play - all the time, everywhere.
"From grassroots activism to worldwide action, we are entering an exciting period of history where the world expects balance. We notice its absence and celebrate its presence. Balance drives a better working world. Let's all help create a #BalanceforBetter."
Who can attend?
Anyone who wishes to. The march, while being women-led, is open to people of all ages, abilities, genders, sexualities and ethnicities. It is entirely free to attend.
The aim is to join in diversity to show presence in numbers around the world too great to ignore.
