Peerage of England
The ranks of the English peerage are, in descending order, Duke, Marquess, Earl, Viscount, and Baron. While most newer English peerages descend only in the male line, many of the older ones (particularly older baronies) can descend through females. Under English inheritance law all daughters are co-heirs, so many older English peerage titles have fallen into abeyance between various female co-heirs.

Baronets, while holders of hereditary titles, are not peers and do not confer nobility. Knights, Dames, and holders of other non-hereditary orders, decorations, and medals of the United Kingdom are also not peers.
