At the end of prehistory, Mankind began to group together in permanent villages. Then, in addition to hunting, fishing and foraging or gathering, they developed agriculture. They also practised livestock farming. This is how humanity gradually became sedentary.
Sedentarization is the act of moving from a nomadic state (moving from one place to another) to a sedentary state (remaining in a permanent place), in reference to a group or population.
History is characterised by populations that have developed the ability to produce their own food: Mankind became farmers and breeders. They no longer had to move around constantly to follow the animals, since they had succeeded in domesticating them. They have chosen a territory and settled there. This new way of life is known as sedentary living.
