This book investigates peaceful societies and the social and ecological conditions that discourage war. The author uses ethnographic examples, cross-cultural findings, primatology, and archaeology to examine war, social organization, human evolution, and conflict management.

In this chapter of 'Beyond War,' Douglas critiques previous codes of warfare to make a distinction between feuding and warring. A test of warfare and level of social complexity among hunter-gatherers is conducted. Results indicate that complex hunter-gatherers make war while a majority of simple hunter-gatherers do not.

In this article, the authors explore cultural variables that they propose contribute to the maintenance of peace in non-warring societies. These variables are compared in 16 peaceful systems (as coded by the authors from anthropological and historical data) and in 30 warring societies taken from the Standard Cross-Cultural Sample (SCCS). Findings associate more peaceful cultures with peace systems, and non-peaceful cultures with warring societies.

Textor summarizes cross-cultural findings on societies where subsistence is primarily by 'food gathering' which includes hunting, fishing, and gathering.

This article examines the incidence of warfare in mobile forager band societies. Data analysis suggests that the majority of lethal aggression in such societies can be classified as homicide. Feuding is common and warfare a definite minority. The authors offer several reasons why warfare would be uncommon in such societies: residence, descent, subsistence strategy, and social order are all cited.

This article challenges common assumptions about hunter-gatherers and demonstrates that previous ideas about residence, division of labor and warfare are not supported by the cross-cultural data.

Drawing from Social Darwinism theories, this article posits warfare (specifically, military success) as a selective mechanism in the evolution of culture. The hypothesis was not supported.

A central issue in anthropology is the process through which political organization (sometimes referred to as cultural complexity) evolves: competing models typically argue for either incremental increases in complexity or larger, non-sequential increases in complexity. Here, the authors evaluate six different models of political evolution, utilizing a phylogenetic approach to analyze the evolution of 84 Austronesian-speaking societies.

This paper tests "theories which suggest that there are causal-functional relationships between the dependent variables peacemaking and peace stability on the one hand and certain independent variables, such as political complexity, warrior class, warfare objectives, cultural homology and intersocietal ties, on the other hand." Significant relationships were found between the last three independent variables.

This study examines how social structure, political organization, and intersocietal relations may affect the incidence of internal warfare (between culturally similar political communities). Results show that in uncentralized political systems, fraternal interest groups and unauthorized raiding parties may increase the incidence of internal war.
