Here's how the Nobel e-Museum describes this interactive map:
In the course of the 20th century, mankind experienced some of the most devastating wars of all times. Where did these wars take place? Have some regions experienced more wars than others? Who were the main protagonists in these conflicts? This map gives you the opportunity to answer these questions. It displays wars with at least 1,000 military battle deaths.You can move a slider on the right side of the screen to change the scale of the map. A slider below the map can change the years displayed. When you position the cursor over war on the map, you can read about that conflict.
The Nobel Peace Prize celebrated its centennial in 2001. Where did the Laureates and nominees come from? How many Africans have received the prize? Alongside the map on wars you will find statistics showing the geographical distribution of Peace Prize nominees and Laureates since 1901.
