Politics and Violence

 Yanamamo rules regarding killing are embedded within kinship obligation and concepts of honor. Rather than being universally condemned, killing is contextually justified, especially in cases of blood revenge. These revenge killings are culturally warranted responses to wrongdoing, particularly the murder or a close kin member. Justice is decentralized, and enacted through this retaliatory violence. The Yanomamo system legitimizes personal retribution, and admires those who participate in it under culturally appropriate conditions. In contrast, Western societies have rules against killing organized in formal legal systems, enforced by the state, intended for individual protection and maintaining social order. Homicide is criminalized, prosecuted, and punished with incarceration or penalties; these formal rules are impersonal and are usually universal despite possible personal injustice. 

Revenge killings, known as nomohori, are an institutionalized form of violence, primarily enacted to avenge the death of a kin member. Carefully coordinated raids often involve coalition-building between male kin and allies. Once alliances are formed, the raiding party travels in stealth and ambushes their enemy. While the person who killed the kin is the target, anyone in the killer’s lineage or village may be targeted and killed symbolically. This not only serves as a means to certify one’s honor, but also prevents future attacks and maintains social balance. Consequently however, these killings can create cycles of feuding between lineages or entire villages, shaping political and social life within the tribe. 

In participating in a revenge raid, killing someone from the offending village, and undergoing the purification ritual upon returning home to his tribe, a man becomes an unokai. This brings a number of social advantages, like elevated status, increased respect, and often political influence. As such, these cultural successes drive biological success as unokai are likely to secure mates and produce a larger number of children compared to non-unokais. While non-unokais spare themselves the danger associated with raids, they occupy lower social status and typically have lower chances for honor and reproductive success. In choosing to become an unokai, a Yanomamo man strategically considers the risk of violence with the potential for increased power, alliances, and children. As these cultural incentives are centered in the Yanomamo society, men have more incentive to participate in revenge killings despite the inherent danger. 

Revenge killings are deeply intertwined with key aspects of their culture, influencing and being influenced by various factors:

The political organization of the Yanomamo is decentralized, and largely based in kinship. Leaders are known as headmen, and gain authority through personal attributes and respect. Rather than being formally elected or appointed, headmen gradually earn their position through showing bravery in raids, their ability to organize retaliation, and the amount of their kin allies. By successfully participating in revenge killings, a man’s political capital is enhanced as he demonstrates the ability to mobilize others, ultimately reinforcing his influence in the village’s politics. 

Additionally, participation in revenge killings directly contributes to social status. A man with a record of bravery and success in raids holds a correlating status. Villages are organized along the lines of kinship and loyalty. As raiding parties organize and ensue, alliances are solidified, and this mutual participation in violence defines itself as loyalty. As bonds are often reshaped through more violence or marriage, this social organization is fluid, but ultimately revolves around a shared hatred or animosity towards an offending village. 

Kinship obligations initiate and justify revenge killings. As a close family member is killed, action to uphold familial honor is demanded. Kin groups are also the primary participants in raids, and as such, these familial bonds are strengthened through this shared purpose. Warfare in the Yanomamo arises from and reinforces kin-based obligations. 

As mentioned above, the cultural success of unokais inspire biological success as these men are observed to have more wives and children than non-unokais. Yanomamo women often prefer to mate with unokais men, as they have demonstrated courage and solidified their social status. It can also be observed that marriage and warfare are intertwined systems; marriage alliances with other villages reduce feuding, which in turn manages inter-village relations, and ensures reproductive success. 

Napoleon Chagnon’s work shows how the absence of centralized authority creates space for personal grievances to escalate into cycles of violence. In Western societies, the presence of laws against homicide deter people who may have the desire to kill, enforcing the social contract. Among the Yanomamo, revenge killings perpetuate intergroup violence and hostility, placing individuals under constant threat of retaliation. However, societies with centralized governance have laws that can resolve disputes without personal violence. This reduces long-term social instability, and ultimately encourages cooperation over conflict. Laws help mitigate violent impulses, like defending honor, avenging kin, or asserting power, and offer alternative structures to personal revenge. Certain circumstances, as seen in Yanomamo villages, rationalize violence out of vengeance, not a natural desire to kill, and laws simply help minimize this.
