After the Acts of Union 1707, the peerage of Scotland elected sixteen of their number, the Scottish representative peers, to sit in the House of Lords at Westminster.
General elections were held with each Parliament, and by-elections to fill vacancies in between.
The elections ceased after the Peerage Act 1963 granted all peers of Scotland an hereditary seat in the House of Lords.
The commissioners for the barons and the burghs chose their representatives to the British House of Commons at the same time.
[1] The elections were not without controversy: in November 1708, four Scottish peers - William Johnstone, 1st Marquess of Annandale, John Earl of Sutherland, Patrick Earl of Marchmont, and William Lord Rosse - presented a petition in the House of Lords complaining of irregularities in the voting which they claimed had led to them being unfairly outvoted by William Kerr, 3rd Marquess of Lothian, and the Earls of Wemyss, Loudoun, and Glasgow.
