Peerage of Great Britain

The Peerage of Great Britain comprises all extant peerages created in the Kingdom of Great Britain after the Act of Union 1707 but before the Act of Union 1800. The Peerage of Great Britain thus replaced the Peerages of England and Scotland, until it was itself replaced by the Peerage of the United Kingdom in 1801. Until the passage of the House of Lords Act 1999, all Peers of Great Britain could sit in the House of Lords. The ranks of the Great British peerage are Duke, Marquess, Earl, Viscount and Baron.
