Representative peer
A representative peer was a hereditary peer of either the Peerage of Scotland or the Peerage of Ireland elected by the members of their respective peerage to represent them in the House of Lords of the Parliament of the United Kingdom.[1] This system originated from the Acts of Union, which united Scotland with England and Wales in 1707 and Ireland with Great Britain in 1801, limiting the number of peers who could sit in the unified Parliament to avoid overwhelming the existing English peerage.[1] Scottish peers elected 16 representatives at the beginning of each Parliament, while Irish peers elected 28 temporal peers alongside 4 spiritual representatives (Irish bishops).[2] The elections for representative peers were conducted by the full body of eligible peers in Scotland and Ireland, with Scottish representatives serving for the life of the Parliament until a convention developed of re-electing incumbents, effectively making terms lifelong in practice.[1] Irish representative peers were initially elected for sessions but later held for life following legislative changes in 1844 and 1868.[2] These peers enjoyed the same rights and privileges in the House of Lords as hereditary peers of England, Great Britain, or the United Kingdom, participating in debates, legislation, and voting on par with them.[3] The institution of representative peers persisted until the mid-20th century, with the Peerage Act 1963 abolishing elections for Scottish peers and granting all holders of Scottish peerages the unqualified right to sit and vote in the House of Lords.[4] For Irish peers, the system effectively ended in 1922 following the partition of Ireland and the establishment of the Irish Free State, after which only peers from Northern Ireland continued limited representation until its termination in 1963.[1] This reform marked a significant expansion of hereditary peer participation, reflecting broader changes in the composition and democratic legitimacy of the upper house.[5]
