Peerage of Great Britain

The Peerage of Great Britain comprises all extant peerages created in the Kingdom of Great Britain between the Acts of Union 1707 and the Acts of Union 1800. It replaced the Peerage of England and the Peerage of Scotland, but was itself replaced by the Peerage of the United Kingdom in 1801.

The ranks of the Peerage of Great Britain are Duke, Marquess, Earl, Viscount and Baron. Until the passage of the House of Lords Act 1999, all peers of Great Britain could sit in the House of Lords.

Some peerages of Great Britain were created for peers in the Peerage of Scotland and Peerage of Ireland as they did not have an automatic seat in the House of Lords until the Peerage Act 1963 which gave Scottish Peers an automatic right to sit in the Lords.

In the following table of peers of Great Britain, holders of higher or equal titles in the other peerages are listed. Those peers who are known by a higher title in one of the other peerages are listed in italics.

Ranks
The ranks of the peerage are Duke, Marquess, Earl, Viscount, and Baron.

Titles
Marquesses, earls, viscounts and barons are all addressed as 'Lord X', where 'X' represents either their territory or surname pertaining to their title. Marchionesses, countesses, viscountesses and baronesses are all addressed as 'Lady X'. Dukes and duchesses are addressed just as 'Duke' or 'Duchess' or, in a non-social context, 'Your Grace'.

Creation of peers
The last non-royal dukedom of Great Britain was created in 1766, and the last marquessate of Great Britain was created in 1796. Creation of the remaining ranks ceased when the United Kingdom of Great Britain and Ireland was formed; subsequent creations of peers were in the Peerage of the United Kingdom.

The last 8 (6 non-royal and two royal) people who were created hereditary peers (from 1798 to 1800) were:
