This year's Nobel Peace Prize has been awarded jointly to three women - Liberian President Ellen Johnson Sirleaf, Liberian Leymah Gbowee and Tawakul Karman of Yemen.
They were recognised for their "non-violent struggle for the safety of women and for women's rights to full participation in peace-building work".
Mrs Sirleaf is Africa's first female elected head of state, Ms Gbowee is a Liberian peace activist and Ms Karman is a leading figure in Yemen's pro-democracy movement.
"We cannot achieve democracy and lasting peace in the world unless women achieve the same opportunities as men to influence developments at all levels of society," said Nobel Committee chairman Thorbjorn Jagland in Oslo.
Reading from the prize citation, he said the committee hoped the prize would "help to bring an end to the suppression of women that still occurs in many countries, and to realise the great potential for democracy and peace that women can represent".
