Did genocide exist in prehistory before the formation of states? With Europe as focus, this article seeks an answer to this seminal question by coupling three lines of archaeological evidence: warfare, abnormal graves and genetics. When warfare is waged against other groups, there is a risk of genocidal events of unconstrained violence. Warfare became more frequent when Neolithic farmers, and later pastoral herders, migrated into the land in several expansions that eventually absorbed or replaced original residents. In the Bronze Age, along with professional military units and higher population densities, abnormal graves increased significantly in frequency. Indeed, warfare is often in evidence in abnormal graves, which call to mind recent examples of genocidal massacres and mass graves. At times, however, there is no apparent reason for the deviant interment. The victims in these graves evidently shared some form of identity. Young women and adolescents are often in minority, probably because they were taken captives and incorporated in the captors’ society as wives and labourers. The conclusion is that genocidal moments took place. Genetic and archaeological evidence corroborates that exposed groups’ possibility to continue reproducing themselves economically, culturally and biologically became restricted. Epidemics is an unknown variable.

The Mongol Empire (1206-1368) had a tremendous impact on slavery across Eurasia. While slaves played a minor role in pre-Imperial Mongolia, the Mongols saw people as a resource, to be distributed among the imperial family and used for imperial needs, like material goods. This view created a whole spectrum of dependency running from free men to full slaves. More specifically, the huge conquests of the United Empire (1206-60) resulted in huge supply of war captives, many of whom eventually sold in the Eurasian slave markets. With the dissolution of the Empire and the halt of its expansion, the demand for slaves remained high, and other means were sought for supplying it. The chapter discusses slavery among the pre-imperial Mongols; the general context of slavery caused by Mongol mobilization and redistribution policies; the various ways of becoming a slave in the Mongol Empire; and the slaves’ dispersion, uses, conditions as well as manumission mechanisms and opportunities for social mobility. It highlights the different types of slavery (extrusive versus intrusive) in China and the Muslim and Christian worlds and argues that in Mongol Eurasia slavery was not always a social death.

The use of physical force was a common experience among the kruso’b in the second half of the nineteenth century. Up to the 1870s, they suffered repeated assaults by government forces. In turn, they exerted violence for practical and expressive purposes against Yucatecan soldiers and civilians, as well as against various pacífico groups, searching for loot, scaring Yucatecans away from their frontier settlements, demoralizing soldiers etc. The chapter discusses the changes in the armament of the rebels and their guerrilla tactics. Kruso’b assaulted settlements in Yucatán ranging from small, entirely Indian hamlets to haciendas, villages and larger towns. Obvious targets were army soldiers, National Guard members, those involved in the self-defense of settlements, and Indians in positions of authority. The kruso’b killed or captured Indians, vecinos, men and women, children and the elderly indiscriminately. Kruso’b behavior during and after raids on Yucatecan or pacífico settlements did not follow a uniform pattern. While members of a certain age, gender or administrative category were slain in some cases, they were spared in others. The taking and the treatment of captives depended on a number of factors, changing rebel needs for labor being one of the most important.
