Hypothesis
The importance of trade will be related to warfare frequency (42)
Note
Relationship found to vary with level of political organization. In independent communities, there is a significant negative correlation between the importance of trade and internal warfare frequency (Rho = -0.22; p = 0.04) and only marginally significant negative correlation between the importance of trade and external warfare (Rho = -0.16; p = 0.09). Within simple chiefdoms there is a significant negative correlation between the importance of trade and external warfare frequency (Rho = -0.28; p = 0.04) and totally insignificant correlation between the importance of trade and internal warfare frequency (Rho = -0.05; p = 0.39) (45).
