Landed gentry is a largely historical privileged British social class consisting of land owners who could live entirely from rental income.
The book, entitled A Genealogical and Heraldic History of the Landed Gentry; or, Commons of Great Britain and Ireland, is often referred to as Burke's Landed Gentry. So popular was the book and the landed gentry within its covers, that numerous editions were revised and published for over 100 years, ending in 1972.
