The Mediterranean race (also Mediterranid race) is an obsolete racial classification of humans based on a now-disproven theory of biological race. According to writers of the late 19th to mid-20th centuries it was a sub-race of the Caucasian race. According to various definitions, it was said to be prevalent in the Mediterranean Basin and areas near the Mediterranean, especially in Southern Europe, North Africa, most of Western Asia, the Middle East or Near East; western Central Asia, parts of South Asia, and parts of the Horn of Africa. To a lesser extent, certain populations of people in Ireland, western parts of Great Britain, and Southern Germany, despite living far from the Mediterranean, were thought to have some minority Mediterranean elements in their population, such as Bavaria, Wales, and Cornwall.
Carleton S. Coon characterized the subgroup as having shorter or medium (not tall) stature, a long (dolichocephalic) or moderate (mesocephalic) skull, a narrow and often slightly aquiline nose, prevalence of dark hair and eyes, and frequently darker skin, ranging from cream to tan or dark brown skin tone; olive complexion being especially common and epitomizing the supposed Mediterranean race.
Racial differentiations occurred following long-standing claims about the alleged differences between the Nordic and the Mediterranean people. Such debates arose from responses to ancient writers who had commented on differences between northern and southern Europeans. The Greek and Roman people considered the Germanic and Celtic peoples to be wild, red haired barbarians. Aristotle contended that the Greeks were an ideal people because they possessed a medium skin-tone, in contrast to pale northerners. By the 19th century, long-standing cultural and religious differences between Protestant northwestern Europe and the Catholic south were being reinterpreted in racial terms.
In the 19th century, the division of humanity into distinct races became a matter for scientific debate.
