Nobility is a social class in aristocracy, normally ranked immediately under royalty, that possesses more acknowledged privileges and higher social status than most other classes in a society and with membership thereof typically being hereditary. The privileges associated with nobility may constitute substantial advantages over or relative to non-nobles, or may be largely honorary, and vary by country and era. The Medieval chivalric motto "noblesse oblige", meaning literally "nobility obligates", explains that privileges carry a lifelong obligation of duty to uphold various social responsibilities of, e.g., honorable behavior, customary service, or leadership roles or positions, that lives on by a familial or kinship bond.
