Peerage of England
In the following table, each peer is listed only by his or her highest English title (with the exception of the Duke of Norfolk/Earl of Arundel) showing higher or equal titles in the other peerages. Those peers who are known by a higher title in one of the other peerages are listed in "italics".
List of viscountcies in the peerages of Britain and Ireland
Viscounts were created in the peerages of England and Scotland until the Act of Union 1707, thereafter being created in the peerage of Great Britain. After the Acts of Union 1800 came into effect in 1801, all peerages were created in the Peerage of the United Kingdom. Viscounts in the Peerage of Ireland were created by English and British monarchs in their capacity as Lord or King of Ireland. Irish peers were not initially granted a seat in the House of Lords and so allowed the grantee to sit in the House of Commons. Viscounts of Ireland have precedence below peers of England, Scotland, and Great Britain of the same rank, and above peers of the United Kingdom of the same rank; but Irish peers created after 1801 yield to United Kingdom peers of earlier creation.
