Abdel Nasser Ould Ethmane is from Mauritania, a country in north-west Africa where slavery has existed for centuries. As a child he thought it was normal for a noble family like his to own slaves, but as he grew older he began to question the practice and ended up as one of the leading campaigners for abolition. He's co-founded an organisation which fights for the rights of enslaved people in Mauritania.
