Uppsala Conflict Data Program

The Uppsala Conflict Data Program (UCDP) is like a really big book that helps people understand all the fights and wars that have happened around the world. It shows you where the fights happened, who was fighting, and how many people were hurt or killed. It helps people see patterns in how wars happen and how they can be prevented in the future. Think of it like a big puzzle where all the pieces help us understand how people can work together to stop fighting and have peace.
