The first war in history (or rather, the first group conflict), according to a theory put forward by some archaeologists, took place in Kenya, near Lake Turkana, about 10,000 years ago. Group conflicts in prehistoryIt is not easy to say when the concept of war was born, that is, the violent clash of a group of men against another group of men. The Nataruk massacre in KenyaA 2012 discovery supports the hypothesis according to which the concept of war precedes the invention of agriculture. According to researchers, who published a study in “Nature” in 2016, the discovery of Nataruk is the oldest evidence of a war or, at least, a gang massacre. The hypotheses are not demonstrable, but it appears clear that the concept of war predates the invention of agriculture.
