The Kaluli are more closely related to the low land Papuan cultural groups than to those of the nearby highlands, physiological and cultural evidence shows this but there is no hard evidence to suggest that they originated anywhere outside of the general territory that they currently occupy. Early trade relations and cultural borrowings appear to have been mainly with peoples from the north and from the west. Over time, the Kaluli moved eastward, away from established settlement areas, moving even more deeply into the forests. Some of this movement may be attributed to a need to seek fresh garden lands, but it may also be explained in part as a defensive response to the expansionist pressures of the
Beami and
Edolo, traditional Kaluli enemies who live to the west and northwest of Kaluli territory. Warfare and raiding were common on the plateau, but there were longstanding trade relations between the Kaluli and certain of the other neighbor groups, particularly with the Sonia to the west and the Huli of the Papuan highlands. First European contact on the plateau occurred in 1935, bringing with it the introduction of new goods to the regional trade network, most significantly, steel axes and knives. World War II brought a temporary stop to Australian government exploration of the plateau, which only began in 1953. At this time, there was more frequent, but still irregular, contacts with Australian administrators and more direct interventions into the lives of the plateau peoples. Raiding and cannibalism were outlawed by 1960, and in 1964 missionaries built an airstrip near Kaluli territory to serve two mission stations established nearby.
