The Gombe Chimpanzee War was a violent conflict between two communities of chimpanzees in Gombe Stream National Park in Tanzania between 1974 and 1978. The two groups were once unified in the Kasakela community. By 1974, researcher Jane Goodall noticed the community splintering.[1] Over a span of eight months, a large party of chimpanzees separated themselves into the southern area of Kasakela and were renamed the Kahama community. The separatists consisted of six adult males, three adult females and their young.[1] The Kasakela was left with eight adult males, twelve adult females and their young.
