paragraph_text: Definitions and conceptual history
  
  Ethnography begins in classical antiquity; after early authors like Anaximander and Hecataeus of Miletus, Herodotus laid the foundation of both historiography and ethnography of the ancient world c. 480 BC. The Greeks had developed a concept of their own ethnicity, which they grouped under the name of Hellenes. Herodotus (8.144.2) gave a famous account of what defined Greek (Hellenic) ethnic identity in his day, enumerating
  
  Whether ethnicity qualifies as a cultural universal is to some extent dependent on the exact definition used. Many social scientists, such as anthropologists Fredrik Barth and Eric Wolf, do not consider ethnic identity to be universal. They regard ethnicity as a product of specific kinds of inter-group interactions, rather than an essential quality inherent to human groups.
  
  According to Thomas Hylland Eriksen, the study of ethnicity was dominated by two distinct debates until recently.
  
  According to Eriksen, these debates have been superseded, especially in anthropology, by scholars' attempts to respond to increasingly politicized forms of self-representation by members of different ethnic groups and nations. This is in the context of debates over multiculturalism in countries, such as the United States and Canada, which have large immigrant populations from many different cultures, and post-colonialism in the Caribbean and South Asia.
  
  Max Weber maintained that ethnic groups were künstlich (artificial, i.e. a social construct) because they were based on a subjective belief in shared Gemeinschaft (community). Secondly, this belief in shared Gemeinschaft did not create the group; the group created the belief. Third, group formation resulted from the drive to monopolize power and status. This was contrary to the prevailing naturalist belief of the time, which held that socio-cultural and behavioral differences between peoples stemmed from inherited traits and tendencies derived from common descent, then called "race".
  
  Another influential theoretician of ethnicity was Fredrik Barth, whose "Ethnic Groups and Boundaries" from 1969 has been described as instrumental in spreading the usage of the term in social studies in the 1980s and 1990s. Barth went further than Weber in stressing the constructed nature of ethnicity. To Barth, ethnicity was perpetually negotiated and renegotiated by both external ascription and internal self-identification. Barth's view is that ethnic groups are not discontinuous cultural isolates or logical a priori to which people naturally belong. He wanted to part with anthropological notions of cultures as bounded entities, and ethnicity as primordialist bonds, replacing it with a focus on the interface between groups. "Ethnic Groups and Boundaries", therefore, is a focus on the interconnectedness of ethnic identities. Barth writes: "... categorical ethnic distinctions do not depend on an absence of mobility, contact, and information, but do entail social processes of exclusion and incorporation whereby discrete categories are maintained despite changing participation and membership in the course of individual life histories."
  
  In 1978, anthropologist Ronald Cohen claimed that the identification of "ethnic groups" in the usage of social scientists often reflected inaccurate labels more than indigenous realities:
  
  ... the named ethnic identities we accept, often unthinkingly, as basic givens in the literature are often arbitrarily, or even worse inaccurately, imposed.
  
  In this way, he pointed to the fact that identification of an ethnic group by outsiders, e.g. anthropologists, may not coincide with the self-identification of the members of that group. He also described that in the first decades of usage, the term ethnicity had often been used in lieu of older terms such as "cultural" or "tribal" when referring to smaller groups with shared cultural systems and shared heritage, but that "ethnicity" had the added value of being able to describe the commonalities between systems of group identity in both tribal and modern societies. Cohen also suggested that claims concerning "ethnic" identity (like earlier claims concerning "tribal" identity) are often colonialist practices and effects of the relations between colonized peoples and nation-states.
  
  According to Paul James, formations of identity were often changed and distorted by colonization, but identities are not made out of nothing:
  
  Categorizations about identity, even when codified and hardened into clear typologies by processes of colonization, state formation or general modernizing processes, are always full of tensions and contradictions. Sometimes these contradictions are destructive, but they can also be creative and positive.
  
  Social scientists have thus focused on how, when, and why different markers of ethnic identity become salient. Thus, anthropologist Joan Vincent observed that ethnic boundaries often have a mercurial character. Ronald Cohen concluded that ethnicity is "a series of nesting dichotomizations of inclusiveness and exclusiveness". He agrees with Joan Vincent's observation that (in Cohen's paraphrase) "Ethnicity... can be narrowed or broadened in boundary terms in relation to the specific needs of political mobilization." This may be why descent is sometimes a marker of ethnicity, and sometimes not: which diacritic of ethnicity is salient depends on whether people are scaling ethnic boundaries up or down, and whether they are scaling them up or down depends generally on the political situation.
  
  Kanchan Chandra rejects the expansive definitions of ethnic identity (such as those that include common culture, common language, common history and common territory), choosing instead to define ethnic identity narrowly as a subset of identity categories determined by the belief of common descent. Jóhanna Birnir similarly defines ethnicity as "group self-identification around a characteristic that is very difficult or even impossible to change, such as language, race, or location."
