Ethnology
Ethnology is described as comparative studies of different peoples, sometimes contrasted with ethnography, as studying only one people at a time. Classified as a branch of anthropology (but ethnic differences are studied by many other fields), after the rise of Boasian anthropology and race denialism, the terms "cultural anthropology" or "social anthropology" are often preferred to ethnology, presumably so as to avoid any impression that races are being studied.
Etymology
The term is from the Greek "ethnos" meaning "people, nation, class, caste, tribe; a number of people accustomed to live together".[1] The term ethnologia (ethnology) is credited to Adam Franz Kollar von Keresztén (1718–1783) who used and defined it in his Historiae ivrisqve pvblici Regni Vngariae amoenitates, published in Vienna, Holy Roman Empire in 1783 as: "the science of nations and peoples, or, that study of learned men in which they inquire into the origins, languages, customs, and institutions of various nations, and finally into the fatherland and ancient seats, in order to be able better to judge the nations and peoples in their own times."
