executive director of UN Women, and distinguished guests.

Today, we are launching a campaign called HeForShe.

I'm reaching out to you because we need your help.

We want to end gender inequality

and to do this, we need everyone involved.

This is the first campaign of its kind at the UN.

We want to try and galvanize as many men and boys as possible to be advocates for change

and we don't just want to talk about it.

We want to try and make sure that it's tangible.

I was appointed as Goodwill Ambassador for UN Women six months ago

and the more I've spoken about feminism, the more I have realized

the fighting for women's rights has too often become synonymous with man-hating.

If there is one thing I know for certain

it is that this has to stop.

For the record, feminism, by definition,

is the belief that men and women should have equal rights and opportunities.

It is the theory of the political, economic, and social equality of the sexes.

I started questioning gender-based assumptions a long time ago.

When I was 8, I was confused being called "bossy"

because I wanted to direct the plays that we would put on for our parents.

but the boys were not.

When at 14, I started to be sexualized by certain elements of the media

When at 15, my girlfriends started dropping out of their beloved sports teams

because they didn't want to appear "muscley".

When at 18, my male friends were unable to express their feelings.

I decided that I was a feminist.

And this seems uncomplicated to me.

But my recent research has shown me that feminism has become an unpopular word.

Women are choosing not to identify as feminists.

Apparently, I'm among the ranks of women whose expressions are seen as too strong

too aggressive, isolating, and anti-men

unattractive, even.

Why has the word become such an uncomfortable one?

I am from Britain.

And I think it is right that I am paid the same as my male counterparts.

I think it is right that I should be able to make decisions about my own body.

(Applause)

I think it is right that women be involved on my behalf in the policies and the decisions that will affect my life.

I think it is right that socially I am afforded the same respect as men.

But sadly, I can say that there is no one country in the world where all women can expect to receive these rights.

No country in the world can yet say that they have achieve gender equality.

These rights I consider to be human rights.

But I am one of the lucky ones.

My life is a sheer privilege

because my parents didn't love me less because I was born a daughter.

My school did not limit me because I was a girl.

My mentors didn't assume that I will go less far because I might give birth to a child one day.

These influences were the gender equality ambassadors that made me who I am today.

They may not know it, that they are the inadvertent feminists who are changing the world today.

We need more of those.

And if you still hate the word, it is not the word that is important.

It's the idea and the ambition behind it.

Because not all women have received the same rights that I have.

In fact, statistically, very few have been.

In 1997, Hillary Clinton made a famous speech in Beijing about women's rights.

Sadly, many of the things that she wanted to change are still true today.

But what stood out for me the most was that less than 30 percent of the audience were male.

How can we affect change in the world when only half of it is invited or feel welcome to participate in the conversation?

Men, I would like to take this opportunity to extend your formal invitation.

(Applause)

Gender equality is your issue, too.

Because to date, I've seen my father's role as a parent being valued less by society

despite my needing his presence, as a child, as much as my mother's.

I've seen young men suffering from mental illness

unable to ask for help, for fear it would make them less of a men, or less of a man.

In fact, in the U.K., suicide is the biggest killer of men, between 20 to 49

eclipsing road accidents, cancer and coronary heart disease.

I've seen men made fragile and insecure by a distorted sense of what constitutes male success.

Men don't have the benefits of equality, either.

We don't often talk about men being imprisoned by gender stereotypes but I can see that they are.

And that when they are free, things will change for women as a natural consequence.

If men don't have to be aggressive in order to be accepted

women won't feel compelled to be submissive.

If men don't have to control, women won't have to be controlled.

Both men and women should feel free to be sensitive.

Both men and women should feel free to be strong.

It is time that we all perceive gender on a spectrum instead of two sets of opposing ideals.

(Applause)

If we stop defining each other by what we are not and start defining ourselves by who we are

we can all be freer and this is what HeForShe is about.

It's about freedom.

I want men to take up this mantle

so that their daughters, sisters and mothers can be free from prejudice

but also so that their sons have permission to be vulnerable and human, too

We claim those parts of themselves they abandoned.

And in doing so, be a more true and complete version of themselves.

You might be thinking, "who is this Harry Potter girl ?"

"And what is she doing speaking at the U.N.?"

And it's a really good question.

I've been asking myself the same thing.

All I know is that I care about this problem and I want to make it better.

And having seen what I've seen and given the chance

I feel it is my responsibility to say something.

Statesman Edmund Burke said

all that is needed for the forces of evil to triumph is for good men and women to do nothing.

In my nervousness for this speech and in my moments of doubt

I've told myself firmly

If not me, who? If not now, when?

If you have similar doubts when opportunities are presented to you

I hope that those words will be helpful

Because the reality is, that if we do nothing

it will take 75 years or for me, to be nearly 100

before women can expect to be paid the same as men for the same work

15.5 million girls will be married in the next 16 years as children

and at current rates, it won't be until 2086 before all rural African girls can have a secondary education.

If you believe in equality

you might be one of those inadvertent feminists that I spoke of earlier

and for this, I applaud you.

We are struggling for a uniting word, but the good news is that we have a uniting movement.

It is called HeForShe.

I am inviting you to step forward to be seen and to ask yourself

If not me, who? If not now, when?

Thank you very, very much.
