From business to sport, women are breaking barriers and burying old stereotypes.
They're transforming countries, managing multi-national companies and making an impact in various industries.
Our list of the most powerful women in the world is not based on financial status, but rather on skills, creativity and influence which has significant impact in their respective fields.
1. Serena Williams: Tennis star
Serena Williams is the highest-paid female athlete in the world.

After winning Saturday’s Wimbledon final, Williams has reached her career best of 22 Grand Slam titles which equals the record set by tennis great, Steffi Graf.

She is also known for her stand with the 'Black Lives Matter' campaign in the US.
2. Angela Merkel: Chancellor of Germany

Merkel opened up her country for hundreds of thousands of migrants fleeing war in Syria.
And she did that despite criticism, and knowing that her political opponents would use it against her.
She has also been leading efforts to convince other countries to do the same, and tried to stop Britain from voting out of the EU.
Being the leader of the European Union's biggest economy, she was at the forefront of efforts to revitalise growth in the region following the 2008 global financial crisis.
Under her leadership, Germany bailed out a sinking EU economy.

From there she went on to graduate as a lawyer, joined the international law firm Baker and McKenzie, and rose to become its first female boss.
She ventured into French politics and ultimately became the first female finance minister for France.

In 1999, Zuma was appointed as Minister of Foreign Affairs and created South Africa's foreign policy based on the promotion of human rights, stability and peace in Africa.
