<P> The Peerage of England comprises all peerages created in the Kingdom of England before the Act of Union in 1707 . In that year, the Peerages of England and Scotland were replaced by one Peerage of Great Britain . </P> <P> Until the passage of the House of Lords Act 1999, all Peers of England could sit in the House of Lords . (Women peers of England were only granted seats with the Peerage Act 1963 .) </P> <P> 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 . </P> <P> 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 . </P>
