>The first chimp war ever observed was the Gombe Chimp War, and it went on for at least four years (1974–1978). A group of chimps had split into two, nicknamed the Kahama and the Kasakela. Shortly after, the Kasakela got violent. They would wait until a Kahama chimp was alone and undefended. Then they would jump him and beat him bloody.Jane Goodall named the leader of the first killing “Satan.” In the aftermath of his killing, she described him as “cupping his hand below Sniff’s chin to drink the blood that welled from a great wound on his face".
