the native religion of the fore was slowly replaced with christianity, due to the establishment of missions and influence of missionaries. this change is partially responsible for the halting of the fore ritual of consuming deceased relatives, which was a primary agent in the rise of the kuru disease. furthermore, the rigidity of clans and clan alliances began to dissolve, due to the halting of warfare and abundance of resources. men and women began to mix more freely, as did people of different clans. trade networks were vastly expanded due to the introduction of roads and more advanced transportation technology. foreign crops and technology were embraced by fore society, such as coffee beans and steel tools. additionally, foreign influence and resources led to the establishment of clinics in the region, which helped decrease fore mortality rates and bring western health practices to the fore.
