The Nobel Peace Prize is one of six awards in the memory of Alfred Nobel, the inventor of dynamite. Every year the organization gives out six awards for the people "who best benefit mankind through their actions" in one of the six subjects; peace, literature, physics, chemistry, economics, and medicine.
The Peace Prize is given out in Norway, but the other Prizes are given out in Sweden. This is because Norway and Sweden were one country when the prizes were started.
Its list of winners includes Martin Luther King, Jr., Elihu Root, Theodore Roosevelt, Woodrow Wilson, Henri La Fontaine, Mikhail Gorbachev, Aung San Suu Kyi, Nelson Mandela, Kofi Annan, Jimmy Carter, Wangari Maathai, Barack Obama, Liu Xiaobo, Juan Manuel Santos and Abiy Ahmed. There is often a lot of controversy about the award of the prize. The 2013 winner is the Organisation for the Prohibition of Chemical Weapons, making it the second year in-a-row that an organization has won the prize, after the European Union did so in 2012.
