Landed gentry is a largely historical privileged British social class consisting of land owners who could live entirely from rental income.
The primary meaning of landed gentry encompasses those members of the land owning classes who are not members of the peerage. It was an informal designation: one belonged to the landed gentry if other members of that class accepted one as such.
