Labour’s 2024 general election manifesto promised to remove the remaining hereditary peers from the House of Lords. Today, the House of Lords (Hereditary Peers) Bill has its second reading in the House of Commons. In this post, Constitution Unit Director and House of Lords expert Meg Russell explores 10 key questions about the bill and Labour’s policy. For example, who are the hereditary peers? How did they get into the House of Lords? How have they survived so long? And what effect will their departure have on the House of Lords? 

1. How long have the hereditary peers been in the House of Lords? 

The history of the House of Lords is long and complex. It is an ancient institution, but has changed very substantially over the years. The roots of the chamber can be traced to bodies that were drawn together to advise the monarch as long ago as the medieval period. Individuals called to those early assemblies were powerful figures, including major landholders and representatives of the church. Around the 14^th century they began meeting separately from others representing the people – so that parliament developed into two distinct chambers, which became the House of Lords and the House of Commons. Initially, there was no guarantee that an individual called to one meeting of the upper chamber would be called to the next. But membership gradually stabilised, and it became established that the members of the nobility who took seats would pass these down the family line along with their titles. By the 13^th century the chamber included earls and barons, while the titles Duke and Marquess date to the 14^th century
