THE POLITICS OF CULTURAL PLURALISM AND ETHNIC CONFLICT
Continuing ethnic tensions in the early years of the twenty-first century seem to confirm Mahabun ul Haq’s prediction—that wars between “people” (ethnic, religious, racial or cultural groups) will continue to far out-number wars between nation-states.
Classic accounts of modernization, particularly those influenced by Marx, predicted that the old basis for divisions, such as tribe and religion, would be swept aside. As hundreds of millions of people poured from rural to urban areas worldwide, during the nineteenth and twentieth centuries, it was expected that new allianceswould be formed, based on social class in particular.
Scholars point out that fear of and hostility toward other ethnic groups are far older and often more entrenched than modern principles of tolerance or equality under the law. “No matter how we may wish for it otherwise, we did not leave violence against outsiders behind us as our nations became modern and democratic.”
Indeed, over the past 50 years, the most frequent settings for violent conflict have not been wars between sovereign states, but rather internal strife tied to cultural, tribal, religious, or other ethnic animosities. Between 1989 and 2004, there were 118 military conflicts in the world. Of those, only seven were between nation-states and the remaining 111 occurred within a single state, a large portion of which involved ethnic conflict.
According to another recent estimate, “nearly two-thirds of all [the world’s] armed conflicts [at that time] included an ethnic component. [In fact], ethnic conflicts [were] four times more likely than interstate wars.” Another study claimed that 80 percent of “major conflicts” in the 1990s had an ethnic element.
Any listing of the world’s most brutal wars in the past few decades would include ethnically based internal warfare or massacres in Rwanda, the Congo, Ethiopia, Sudan, Lebanon, and Indonesia (East Timor). In 1998, one authoritative study estimated that some 15 million people had died worldwide as a result of ethnic violence since 1945 (including war-related starvation and disease).
In the decade since, at least 5 million additional deaths resulted from ethnic conflict in the Congo alone, with hundreds of thousands more in Sudan, Ethiopia, Afghanistan, Iraq, and elsewhere. Since the end of the Cold War, the world’s attention has focused increasingly on ethnic clashes. Some experts predict that poor, densely populated countries will experience increased ethnic conflict over scarce resources (such as farmland) in the coming decades. Warfare between Serbs, Croats, Bosnian Muslims, and Kosovars in the former Yugoslavia, along with separatist movements by French-speaking Québécois, racially based riots in Los Angeles, Basque terrorism in Spain, and Protestant–Catholic clashes in Northern Ireland all demonstrate that interethnic friction and violence can erupt in both Western democracies and former European communist countries.
The intensification of ethnic, racial, and cultural hostilities during the twentieth century undercut several assumptions of modernization theory; it also contradicted an influential social psychology theory known as the “contact hypothesis.” That hypothesis predicted that as people of different races, religions, and ethnicities came into greater contact with each other, they better understand the other groups’ common human qualities, causing prejudice to decline.11 Although the contact hypothesis frequently predicts individual level attitudes and behavior (i.e., as individuals of different races or religions come to know each other better, their prejudices often diminish), increased interaction between different ethnic groups, occasioned by factors such as urban migration, frequently intensifies hostilities.

– “The Evolutionary Dominance of Ethnocentric Cooperation” - "Recent agent-based computer simulations suggest that ethnocentrism, often thought to rely on complex social cognition and learning, may have arisen through biological evolution. From a random start, ethnocentric strategies dominate other possible strategies (selfish, traitorous, and humanitarian) based on cooperation or non-cooperation with in-group and out-group agents. Here we show that ethnocentrism eventually overcomes its closest competitor, humanitarianism, by exploiting humanitarian cooperation across group boundaries as world population saturates."
