nobility

thumb|286x286px|The House of Lords is the upper legislature of the [[Parliament of the United Kingdom and is filled with members that are selected from the aristocracy (both hereditary titleholders and those ennobled only for their individual lives).]] Nobility is a social class found in many societies that have an aristocracy. It is normally appointed by and ranked immediately below royalty. Nobility has often been an estate of the realm with many exclusive functions and characteristics. The characteristics associated with nobility may constitute substantial advantages over or relative to non-nobles or simply formal functions (e.g., precedence), and vary by country and by era. Membership in the nobility, including rights and responsibilities, is typically hereditary and patrilineal.

Membership in the nobility has historically been granted by a monarch or government, and acquisition of sufficient power, wealth, ownerships, or royal favour has occasionally enabled commoners to ascend into the nobility.
