Chimpanzee Civil War Erupts in Uganda's Kibale Park
20 Apr
Summary
- Chimpanzees in Uganda's Kibale National Park are engaged in a rare 'civil war'.
- The conflict began in 2015, splitting a large community into two factions.
- Violence has resulted in lethal attacks on both adult and infant chimps.

A remarkable chimpanzee 'civil war' is currently unfolding in Uganda's Kibale National Park, a phenomenon rarely observed in the wild. This conflict began around June 2015 when a large chimpanzee community, numbering over 200 individuals, fractured into two distinct groups: the Western and Central chimps. This division has led to escalating violence and territorial patrols between the factions.
The Western chimps have exhibited heightened aggression, conducting patrols that have resulted in lethal attacks on members of the Central group. Since 2018, these attacks have claimed the lives of several adult and infant chimps. Researchers, who have observed this rare event, are gaining unique insights into intergroup conflict and the complex social dynamics within chimpanzee societies.
This observed conflict in Ngogo mirrors a previous 'civil war' documented by primatologist Jane Goodall in the 1970s. Scientists hypothesize that changes in dominance hierarchies and potential health issues within the Ngogo community may have weakened social ties, triggering the current internecine conflict. The implications of this research extend to understanding human conflict, as it highlights the role of relational dynamics in societal strife.
