Peerage of the United Kingdom

The Peerage of the United Kingdom comprises most peerages created in the United Kingdom of Great Britain and Ireland after the Acts of Union in 1801, when it replaced the Peerage of Great Britain. New peers continued to be created in the Peerage of Ireland until 1898.
The House of Lords Act 1999 reformed the House of Lords. Until then, all peers of the United Kingdom were automatically members of the House of Lords. However, from that date, most of the hereditary peers ceased to be members, whereas the life peers retained their seats. All hereditary peers of the first creation, and all surviving hereditary peers who had served as Leader of the House of Lords, were offered a life peerage to allow them to sit in the House should they wish.
Some holders of the Peerage of United Kingdom was 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.
