International Women's Day 2023: History, marches and celebrations

But what is this day for? When is it? Is there an equivalent International Men's Day? And what events will take place this year?

For more than a century people around the world have been marking 8 March as a special day for women.

Read on to find out why.

How did it start?

International Women's Day, also known as IWD for short, grew out of the labour movement to become a recognised annual event by the United Nations (UN).

The seeds of it were planted in 1908, when 15,000 women marched through New York City demanding shorter working hours, better pay and the right to vote. A year later, the Socialist Party of America declared the first National Woman's Day.

The idea to make the day international came from a woman called Clara Zetkin, communist activist and advocate for women's rights. She suggested the idea in 1910 at an International Conference of Working Women in Copenhagen. There were 100 women there, from 17 countries, and they agreed on her suggestion unanimously.

It was first celebrated in 1911, in Austria, Denmark, Germany and Switzerland. The centenary was celebrated in 2011, so this year we're technically celebrating the 111th International Women's Day.

Things were made official in 1975 when the United Nations started celebrating the day. The first theme adopted by the UN (in 1996) was "Celebrating the Past, Planning for the Future".

International Women's Day has become a date to celebrate how far women have come in society, in politics and in economics, while the political roots of the day mean strikes and protests are organised to raise awareness of continued inequality.

Why 8 March?

Clara's idea for an International Women's Day had no fixed date.

It wasn't formalised until a war-time strike in 1917 when Russian women demanded "bread and peace" - and four days into the strike the Tsar was forced to abdicate and the provisional government granted women the right to vote.

The date when the women's strike commenced on the Julian calendar, which was then in use in Russia, was Sunday 23 February. This day in the Gregorian calendar was 8 March - and that's when it's celebrated today.

Why do people wear the colour purple?

Purple, green and white are the colours of IWD, according to the International Women's Day website.

"Purple signifies justice and dignity. Green symbolizes hope. White represents purity, albeit a controversial concept. The colours originated from the Women's Social and Political Union (WSPU) in the UK in 1908," they say.

Is there an International Men's Day?

There is indeed, on 19 November.

But it has only been marked since the 1990s and isn't recognised by the UN. People celebrate it in more than 80 countries worldwide, including the UK.

The day celebrates "the positive value men bring to the world, their families and communities", according to the organisers, and aims to highlight positive role models, raise awareness of men's well-being, and improve gender relations.

How is Women's Day celebrated?

International Women's Day is a national holiday in many countries, including Russia where flower sales double during the three or four days around 8 March.

In China, many women are given a half-day off work on 8 March, as advised by the State Council.

In Italy, International Women's Day, or la Festa della Donna, is celebrated by the giving of mimosa blossoms. The origin of this tradition is unclear but it is believed to have started in Rome after World War Two.

In the US, the month of March is Women's History Month. A presidential proclamation issued every year honours the achievements of American women.

What is the IWD 2023 theme?

The UN's theme for 2023 is "DigitALL: Innovation and technology for gender equality". This theme aims to recognise and celebrate the contribution women and girls are making to technology and online education.

This year, IWD will also explore the impact of the digital gender gap on inequality for women and girls, as the UN estimates that women's lack of access to the online world will cause a $1.5 trillion loss to gross domestic product of low and middle-income countries by 2025 if action isn't taken.

But there are also other themes around. The International Women's Day website - which says it's designed to "provide a platform to help forge positive change for women" - has chosen the theme #EmbraceEquity with organisers and events seeking to "challenge gender stereotypes, call out discrimination, draw attention to bias, and seek out inclusion".

Why do we need it?

In the past year, women in many countries such as Afghanistan, Iran, Ukraine and the US have been fighting for their rights amid war, violence and policy changes in their respective countries.

In Afghanistan, the resurgence of the Taliban has hindered advancements in human rights with women and girls now banned from higher education, working most jobs outside of the home, travelling long distances without a male chaperone and they are instructed to cover their faces in public.

In Iran, protests were sparked by the death of Mahsa Amini, a 22-year-old woman arrested by morality police in Tehran on 13 September 2022 for allegedly violating Iran's strict rules requiring women to cover their hair with a scarf.

Since then, demonstrations have continued across the country with many Iranians - both female and male - calling for better rights for women and a change from the current political leadership. "Woman, life, freedom" is the slogan of the protests. Authorities have portrayed them as "riots" and responded with force. More than 500 people have died.

Following the invasion of Ukraine by Russian forces on 24 February 2022, the UN report that gender gaps in food insecurity, malnutrition, poverty, and increased gender-based violence have worsened inside Ukraine and around the world due to war-induced price hikes and shortages.

On June 24 2022, the US Supreme Court overturned Roe v Wade, a historic piece of legislation which protected the right to abortion for American women, causing widespread outcry and demonstrations in the US. A number of US women have sought support to get a termination from people in Mexico, where a historic ruling in 2021 effectively decriminalised abortion.

In the past few years though, there has been progress.

In November 2022, the European Parliament passed a law after a 10-year battle to ensure more women are represented on publicly traded companies' boards by July 2026. "There are plenty of women qualified for top jobs and with our new European law, we will, make sure that they have a real chance to get them," the EU said.

Meanwhile parental leave laws were updated in Armenia and Colombia, and Spain passed laws to support menstrual health leave and extended access to abortion.

The International Olympic Committee reported the most gender-balanced Winter Games with women making up 45% of athletes at Beijing 2022. Though gender parity wasn't achieved, new guidelines promoted more balanced coverage of women's sport.

The Fifa Women's World Cup in 2023 is newly expanded, with 36 teams taking part. Ahead of the competition, the US Soccer Federation reached a historic agreement to pay its men's and women's teams equally, making it the first in the sport to promise both sexes matching money. Female players had filed a number of equal pay claims and lawsuits, arguing their case for more than five years.
