Newsround is taking a look back at the achievements of some women who have well and truly left their mark on history through amazing things that they have done.
Let's start with a literary figure who has had more influence on British culture than she would ever have known during her relatively short life (she sadly died at the age of 41).
Jane Austen started putting pen to paper when she was just a teenager and went on to write six major novels which revealed what life was like in the late 1700s and early 1800s. Four of them were released within just four years of each other! That's some seriously rapid writing.
These were Sense and Sensibility, Pride and Prejudice, Mansfield Park, and Emma. Northanger Abbey and Persuasion were published after she died - and they are loved all over the world. There was actually a seventh and final novel, but sadly she never got to complete it.
While she was alive, she actually published her books anonymously, so nobody knew her as a writer. It is widely accepted that she never got the credit she deserved until after her death.
Now, just over 200 years since she died, millions of people carry Jane around in their pockets every single day. That's because her face is now on the new £10 note as a way of marking just what an enormous impact her work still has today.
If there was ever a true hero who dedicated her life to helping others, Florence Nightingale is it. Born in Italy in 1920, Florence went against what was traditionally expected of her, by becoming a war-hero nurse.
She was born in Florence - which was the inspiration for her name (fun fact!) - into a very wealthy family who frowned upon her entering into the nursing profession.
She moved to London to work before receiving a letter from the Secretary of War asking her to put a team together to go to work in a place called Crimea during the Crimean War, and look after British soldiers. This was the first time that women had been officially allowed to serve in the army.
The conditions there were terrible. For example, there weren't enough beds, everything was filthy, there weren't proper loos and there were rats everywhere.
When she first arrived in November 1854, the army doctors wanted nothing to do with her. But she wouldn't go away and soon got to work cleaning up the awful conditions there. She quickly got the more able soldiers to work making them scrub the hospital clean.
She used to walk around the hospital at night to make sure the poorly soldiers were comfortable. This is how she became known as the lady with the lamp.
She was welcomed home a hero. Even Queen Victoria wrote her a letter to say thank you for what she'd done. It's not every day that you get a thank you letter from the Queen!
Florence Nightingale completely transformed the quality of care in war and went on to improve healthcare all over the world, so that's a pretty amazing legacy to leave.
Emmeline Pankhurst was a founding member of a group of women called the Suffragettes, who fought incredibly hard to get women the right to vote in the UK.
They often used violent and extreme tactics to do this, and Emmeline was no stranger to a prison cell because of this.
When World War One broke out, however, she recognised that she should help with the war effort, and she encouraged other Suffragettes to do the same.
While the men were away fighting in the war, many women like Emmeline took on jobs that men would traditionally do. They earned lots of respect doing this and it showed just how much women contributed to society - and, therefore, deserved the vote.
In 1918, a law was passed which allowed certain women the right to vote. This was a big step in equality between men and women - and many would argue that, for a large part of this, we have Emmeline to thank.
Marie Curie was a Polish scientist - and is probably one of the most famous scientists of all time. She was born in the Polish city of Warsaw, but later moved to France where she made an incredible discovery which would change the world.
In France, she met her husband - a man called Pierre, who was also a scientist. Together, they built on work done by previous scientists and made discoveries which would earn them a Nobel Prize in 1903.
As if that wasn't enough, Marie went on to win another Nobel Prize in 1911. She was the first woman in history to win it.
So what was this amazing work? Well, the Curies made ground-breaking discoveries about something called radioactivity. Radioactivity happens when certain special chemical elements give off energetic particles when a part of them called their nucleus breaks down.
This all sounds rather technical, but through this work, the Curies announced the discovery of two new chemical elements - polonium and radium.
And why was that so important? Well, first of all, their work was used to develop something called radiotherapy, which is used to treat certain illnesses.
These discoveries were also really important in developing X-rays, which are vital in hospitals today. It also meant that during World War One, Curie was able to develop a portable X-ray unit that could be used near the battlefront.
So if you ever find yourself in hospital having an X-ray, you now know who you should be thanking.
From science to one of the most iconic brands in the fashion world - Coco Chanel was a woman who changed the face of fashion forever.
She was born in France and taught herself to sew at a young age - something that would certainly come in handy later on!
She opened her first shop in the early 1900s, starting off by designing hats. She soon turned her attention to clothes too and, by the 1920s, launched her first perfume.
Ever heard of the saying the 'little black dress', also known as the LBD? Yep, you have Coco Chanel to thank for that.
She led the way in luxury fashion and today her brand - led by its creative director Karl Lagerfeld - sells clothes, perfume, handbags and watches. Almost 100 years after it was first created, Chanel No 5 is still probably the world's most famous perfume!
All from one hat shop, Chanel is now worth billions of pounds, so it's safe to say she had one heck of an impact!
Katharine Hepburn was quite the fashion icon, but one of the main ways that she left her mark was by changing the idea of what people believed it was to be feminine.
One way that she did this was by challenging how women were supposed to dress. In Hollywood in the 1930s and 1940s, it was more usual for women to wear dresses and skirts. But no, Katharine liked to wear trousers and she became very well known for this.
She was an extremely independent woman and took control of her own acting career - again, something that wasn't very usual for women at that time.
She once said: "I've had a pretty remarkable life, but compared to my mother and father, I'm dull." Well, Katharine, we - and millions of others - think you were anything but.
In September 2016, it was announced that Mother Teresa was being named as a Saint - so she is certainly deserving of a place on this list.
At the age of 12, Teresa - who was a Roman Catholic - decided that she wanted to go to India to spread the Christian message and help people.
So this she did. In 1929, she travelled to India and she ended up dedicating her life to helping poor people, particularly in the Indian city of Kolkata. She described her work as God's work.
While she was there, she started something called the Missionaries of Charity. This group now has thousands of people in almost 90 countries helping people living in poverty all over the world.
In 1979 she received the Nobel Peace Prize for her work. She asked that the big dinner to mark this was cancelled and all of the money given to the poor people of Kolkata.
It is said that she only had two possessions of her own - a bucket and two saris. To this day, she is remembered by how much she loved and cared for people, and praised as a Saint.
Margaret Thatcher changed the face of modern British politics.
She started her political career at Oxford University where she was president of the Conservative Association. She later ran for parliament to represent Dartford, but she lost out twice to her Labour rival.
In 1959, though, she won the parliamentary seat in Finchley and became Margaret Thatcher MP.
But she really made history in 1975 when she became leader of the Conservative Party - one of the two major political parties in the UK - and later, in 1979, the first female British Prime Minister.
She had some pretty radical views and even earned herself the nickname the Iron lady. She was forced to quit in 1990, but not before she'd become the longest continuously serving prime minister of the 20th century.
As with most political figures, some people loved her, while others didn't. Some thought she saved Britain when it was having many economic problems. Others thought she ruined the lives of millions of workers.
Whatever people think, there's no question that her strong-mindedness certainly meant she left her mark on British politics.
At the grand age of 91 years old, Her Majesty is incredibly deserving of her place on a list of women who have left their mark on the world.
She has been sitting on the throne for 66 years, making her the world's longest serving monarch. She has seen the country through good times and bad, as well as sitting with 12 different prime ministers. Phew!
She was just 25 years old when her father died and the crown was passed on to her - and she has been in the spotlight almost every day of her life.
The Queen is an incredibly busy lady. She has many important jobs, including being Head of the Commonwealth, Head of the Church of England and Head of the Armed Forces.
She also has to carry out many extremely important duties like officially opening parliament once a year (the country would be in a spot of bother if that didn't happen!). She even manages to fit in two birthdays a year.
Well, while two birthdays a year sounds like a lot of fun, there's no denying that the Queen has worked incredibly hard throughout her life and has certainly made British monarchy history.
One woman whose name you will probably have heard many times over the last couple of years is Hillary Clinton.
That's because she made history back in July 2016 when she became the first woman from one of America's two main political parties to be chosen to run for the job of president. She was representing the Democrats - the same party as the president at the time, Barack Obama.
While she did not win the presidential race - the Republican candidate Donald Trump got the top job - she inspired millions of girls and women all over the world.
At the end of 2017, she sat down with a group of young girls for Teen Vogue. She told the group that she did not plan to go for the job again, but that she would be supporting other people who wanted to do it - especially young women.
So it sounds like she has ambitions to leave her mark on the future too.
One woman who is rarely away from the headlines is media legend Oprah Winfrey.
She started off her TV career when she was just a teenager, becoming the youngest person - and first African-America woman - to read the main news on a channel in the city of Nashville in America at the age of 19.
Now, she is the one of the world's most famous and most-loved interviewers.
She first became famous in 1986 with the Oprah Winfrey Show. It ran for 25 years before she turned her success into her own TV channel - the Oprah Winfrey Network.
She has also done a huge amount of charity work, including setting up two of her own foundations and donating millions of her own money.
Some people think that after giving a powerful speech at an awards ceremony in America recently that she should run to be the next US president. Whether or not she will do that, only Oprah knows.
We suspect we don't need to tell you how this woman has changed the world.
Through her books, author Joanne Kathleen Rowling (JK Rowling) brought the world one of the most-loved and most famous literary characters ever. We are of course talking about a certain Harry Potter.
It's hard to imagine now but Rowling did actually struggle to get the book published at first (can you imagine?!).
Since their publication though, the books have been turned into an unbelievably successful series of films, which launched the careers of Hollywood royalty Emma Watson and Daniel Radcliffe.
She has also published books under a different name, Robert Galbraith. Some publishers rejected books that 'Robert Galbraith' had written, with one even saying that 'he' should go on a writing course! We bet they were rather embarrassed when they found out who 'he' really was.
As the first female novelist to become a billionaire, we think it's safe to say she has left a lightning bolt-shaped scar in history!
Many of us will have sports stars who we massively look up to. Jessica Ennis-Hill is one of those stars who inspired millions of people during the London 2012 Olympics.
She first got into athletics at school and took home her first official medal from the Commonwealth Games in Australia, back in 2006. This was to be the first of many medals to come and just three years later, she got her her first gold medal in the 2009 World Championships in Germany.
But it was the London 2012 Olympics that really secured her spot in the history books.
Jessica was named as the main face of the Games in the run-up to the Olympics, so she starred in adverts and lots of campaigns promoting the event. Her face was plastered on billboards and screens up and down the country.
So you'd have thought the pressure might have got to her - but not a bit of it. Jessica went and won gold in the heptathlon, before going on to win silver in the Rio Olympics just four years later.
Not long after, she announced her retirement from athletics and was deservedly made a Dame in 2017's New Year's Honours.
As a young girl of 11, the Pakistani student wrote an anonymous diary about what life was like under the rule of an extreme group called the Taliban in north-west Pakistan.
In the diary, she talked about how she wanted to stay in education and about how girls should be able to go to school. The Taliban wanted to ban girls' education. Lots of people read the diary all over the world and she became well-known for fighting for her right to an education.
But the Taliban didn't like this. Because of what she said in her diary, in October 2012, she was shot by their soldiers - but she survived the attack.
The world was appalled by what happened to her and Malala quickly won the support of millions more people.
At 14, she became the youngest person ever to win the Nobel Peace Prize. When she received it, she joked that she was probably the first winner who still fought with her younger brothers!
She has gone on to win more awards, and continues to campaign for girls' rights all over the world and inspire many generations.
