Gentry (from Old French genterie, from gentil, "high-born, noble") are "well-born, genteel and well-bred people" of high social class, especially in the past. Gentry, in its widest connotation, refers to people of good social position connected to landed estates (see manorialism), upper levels of the clergy or "gentle" families of long descent who in some cases never obtained the official right to bear a coat of arms. The gentry largely consisted of landowners who could live entirely from rental income, or at least had a country estate; some were gentleman farmers. In the United Kingdom, the term gentry refers to the landed gentry: the majority of the land-owning social class who typically had a coat of arms, but did not have a peerage. The adjective "patrician" ("of or like a person of high social rank") describes in comparison other analogous traditional social elite strata based in cities, such as free cities of Italy (Venice and Genoa), and the free imperial cities of Germany, Switzerland, and the Hanseatic League.
The term "gentry" by itself, so Peter Coss argues, is a construct that historians have applied loosely to rather different societies. Any particular model may not fit a specific society, yet a single definition nevertheless remains desirable.
The Indo-Europeans who settled Europe, Central and Western Asia and the Indian subcontinent conceived their societies to be ordered (not divided) in a tripartite fashion, the three parts being castes. Castes came to be further divided, perhaps as a result of greater specialisation.
The "classic" formulation of the caste system as largely described by Georges Dumézil was that of a priestly or religiously occupied caste, a warrior caste, and a worker caste. Dumézil divided the Proto-Indo-Europeans into three categories: sovereignty, military, and productivity (see Trifunctional hypothesis). He further subdivided sovereignty into two distinct and complementary sub-parts. One part was formal, juridical, and priestly, but rooted in this world.
