Children's rights activists Malala Yousafzai of Pakistan and Kailash Satyarthi of India and have won the Nobel Peace Prize.
The Norwegian Nobel Committee cited the two "for their struggle against the suppression of children and young people and for the right of all children to education".
Malala, 17, is a schoolgirl and education campaigner in Pakistan who was shot in the head by a Taliban gunman two years ago.
Mr Satyarthi has maintained the tradition of Mahatma Gandhi and headed various forms of peaceful protest, "focusing on the grave exploitation of children for financial gain", the Nobel committee said.
The Nobel Committee said it "regards it as an important point for a Hindu and a Muslim, an Indian and a Pakistani, to join in a common struggle for education and against extremism".
The founder of the Nobel Prizes, Swedish industrialist Alfred Nobel, said the prize committee should give the prize to "the person who shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses".
The committee has interpreted those instructions differently over time, widening the concept of peace work to include efforts to improve human rights, fight poverty and clean up the environment.
