Organized warfare.

[RascalPuff]

What's particularly noteworthy about this history is, it is not written by any potentially revisional historians, but rather, by archeaologists, paeleantologists and anthropologists.

Until fairly recently, prehistoric dated warfare was academically considered to be relatively unusual. But forensic digs continue to yield startling evidence to the contrary.

War before civilization
In his book War Before Civilization, Lawrence H. Keeley, a professor at the University of Illinois, calculates that 87% of tribal societies were at war more than once per year, and some 65% of them were fighting continuously.
One half of the people found in a Nubian cemetery dating to as early as 12,000 years ago had died of violence. The Yellowknives tribe in Canada was effectively obliterated by massacres committed by Dogrib Indians, and disappeared from history shortly thereafter. Similar massacres occurred among the Eskimos, the Crow Indians, and countless others. These mass killings occurred well before any contact with the West. In Arnhem Land in northern Australia, a study of warfare among the Indigenous Australian Murngin people in the late-19th century found that over a 20-year period no less than 200 out of 800 men, or 25% of all adult males, had been killed in intertribal warfare. The accounts of missionaries to the area in the borderlands between Brazil and Venezuela have recounted constant infighting in the Yanomami tribes for women or prestige, and evidence of continuous warfare for the enslavement of neighboring tribes such as the Macu before the arrival of European settlers and government. More than a third of the Yanomamo males, on average, died from warfare.
In fact, says Keeley, it is peaceful societies that are the exception. About 90-95% of known societies engage in war. Those that did not are almost universally either isolated nomadic groups (for whom flight is an option), groups of defeated refugees, or small enclaves under the protection of a larger modern state. The attrition rate of numerous close-quarter clashes, which characterize warfare in tribal warrior society, produces casualty rates of up to 60%, compared to 1% of the combatants as is typical in modern warfare. Despite the undeniable carnage and effectiveness of modern warfare, the evidence shows that tribal warfare is on average 20 times more deadly than 20th century warfare, whether calculated as a percentage of total deaths due to war or as average deaths per year from war as a percentage of the total population. "Had the same casualty rate been suffered by the population of the twentieth century," writes Nicholas Wade, "its war deaths would have totaled two billion people."
According to Keeley, even among the supposedly peaceful Indigenous peoples of the Americas, only 13% did not engage in wars with their neighbors at least once per year. The natives' pre-Columbian ancient practice of using human scalps as trophies is well documented. Iroquois routinely slowly tortured to death and cannibalized captured enemy warriors.[citation needed] In some regions of the American Southwest, the violent destruction of prehistoric settlements is well documented and during some periods was even common. For example, the large pueblo at Sand Canyon in Colorado, although protected by a defensive wall, was almost entirely burned; artifacts in the rooms had been deliberately smashed; and bodies of some victims were left lying on the floors. After this catastrophe in the late thirteenth century, the pueblo was never reoccupied.
Professor Keeley conducts an investigation of the archaeological evidence for prehistoric violence, including murder and massacre as well as war. He also looks at nonstate societies of more recent times — where we can name the tribes and peoples — and their propensity for warfare with surprisingly deadly cumulative effects. It has long been known, for example, that many tribes of South America's tropical forest engaged in frequent and horrific warfare, but some scholars have attributed their addiction to violence to baneful Western influences. Keeley produces evidence of frequent deadly raids and occasional wholesale massacres over much of prehistoric North America, arguing that this archaeological evidence indicates that these massacres were not only prior to Western contact, but also more severe than anything reported in the ethnographic record for the region.
For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilated during an attack on their village a century and a half before Columbus's arrival (ca. A.D. 1325). The Crow Creek massacre seems to have occurred just when the village's fortifications were being rebuilt. All the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60% of the village's population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilated in a single attack and never reoccupied.[1]

Here is my quote from post number 2

Pre-historic warfare, for which there is some evidence, may have consisted of only a few tens of combatants, but relative to the population of the area at the time it could be considered large scale.

Statistics show that we are improving. Cursorily, common sense, derived from media items would imply the reverse, that war is more destructive and prevalent than ever before.

Here is a quote from my blog

"We were born of risen apes, not fallen angels, and the apes were armed killers besides. And so what shall we wonder at? Our murders and massacres and missiles, and our irreconcilable regiments? Or our treaties whatever they may be worth; our sympathies however seldom they may be played; our peaceful acres, however frequently they may be converted to battlefields; our dreams however rarely they may be accomplished.
The miracle of man is not how far he has sunk but how magnificently he has risen. We are known among the stars by our poems, not our corpses."

cool bananas ... greg

PS: So far an arms length reader of this thread would have to agree that I am ahead on points .... LOL. I think you need to redefine 'Organised War' ... LOL
