A nation (from Latin: natio, "people, tribe, kin, genus, class, flock") is a large group or collective of people with common characteristics attributed to them — including language, traditions, mores (customs), habitus (habits), and ethnicity. By comparison, a nation is more impersonal, abstract, and overtly political than an ethnic group. It is a cultural-political community that has become conscious of its autonomy, unity, and particular interests.
Joseph Stalin's Marxism and the National Question (1913) declares that "a nation is not a racial or tribal, but a historically constituted community of people;" "a nation is not a casual or ephemeral conglomeration, but a stable community of people"; "a nation is formed only as a result of lengthy and systematic intercourse, as a result of people living together generation after generation"; and, in its entirety: "a nation is a historically constituted, stable community of people, formed on the basis of a common language, territory, economic life, and psychological make-up manifested in a common culture."
The nation has been described by Benedict Anderson as an "imagined community" and by Paul James as an "abstract community". It is an imagined community in the sense that the material conditions exist for imagining extended and shared connections. It is an abstract community in the sense that it is objectively impersonal, even if each individual in the nation experiences him or herself as subjectively part of an embodied unity with others. For the most part, members of a nation remain strangers to each other and will never likely meet. Hence the phrase, "a nation of strangers" used by such writers as Vance Packard.
