Achuar feuding increased dramatically from 1940-70, then declined in the 1970s. These general changes in Jivaro warfare were shown to correspond to changes in the availability of Western goods. Moreover, evidence was given that the Jivaro had a strong desire to obtain manufactured valuables and that access to these items became an important basis of power for great men. That such motives could incite violence and alter the course of war was supported by analysis of particular cases, informants' statements to this effect, and an analysis of the process by which would-be assassins sought support for their ventures. Finally, other proposed explanations of Jivaro warfare fail to adequately account for the historical events described in this essay. Although I have only considered the Achuar and the Shuar here, there is reason to think that similar arguments could be developed for the other main Jivaro groups, the Aguaruna and the Huambisa. Beginning around the 1810s, the Aguaruna and the Huambisa initiated a series of devastat- - ing raids on Peruvian frontier towns in their area, obliterating some towns completely and often causing other towns to relocate (Guallart 1990: 139-47). The Aguaruna and the Huambisa were involved in the 1880-1915 rubber boom, and the Aguaruna were engaged in head-hunting raids (ibid.: 163-82; Bennett Ross 1980: 56).The explorer F. W. Up de Graff (1923: 238- go) provides a detailed eye-witness account of an Aguaruna tsantsa raid from this period that illustrates how manufactured valuables (provided by himself in this case) could stimulate violent action. From about 1950 to 1970 many Aguarunas and Huambisas labored for Peruvian patrones, often under exploitative conditions (Brown 1986: 38). In the early 1970s a new Peruvian government passed Indian-friendly laws that ultimately ended the patrones system, which may be related to the fact that the severe Aguaruna feuding of previous decades was a dim memory by 1978 (ibid.: 38-44). Anthropological theorizing about Jivaro warfare, then, would benefit from further inquiry into the influence of manufactured valuables.\" §REF§Steel, Daniel 1999. \"Trade Goods and Jívaro Warfare: The Shuar 1850-1957, and the Achuar, 1940-1978\", 772p§REF§ Given how his evidence dates from the Ecuadorian period, we have assumed that the goods in question were not in widespread use prior to the Ecuadorian period.
