List of constituencies in the Parliament of Scotland at the time of the Union is a list of the constituencies of the Parliament of Scotland (the Estates of Scotland) during the period shortly before the Union between the Kingdom of Scotland and the Kingdom of England. The unicameral Estates of Scotland existed from medieval times until 1707. The Commissioners for the burghs (the "Third Estate") and shires and stewartries (sometimes called the "Fourth Estate", or classified as a subgroup within the "Second Estate") were elected, but on a very restrictive franchise. Commissioner was the title for ordinary, representative members of the parliament (junior peers were called Lords of Parliament; and senior peers, representatives of the monarch, and certain members of the clergy also sat in parliament). The Scottish ministers (the Privy Council of Scotland), were not answerable to the Estates of Scotland but to the Scots monarch (which, after the Union of Crowns in 1603, usually meant de facto to the Privy Council of England, which had the opportunity to advise a king or queen resident in London). The Parliament of Scotland was abolished when it merged with the Parliament of England to create the new Parliament of Great Britain, in 1707 under the Acts of Union. Constituencies The representation of the burghs and those of the shires and stewartries, by the time of the Union, consisted of 154 Commissioners elected from 99 constituencies. An election was not held immediately after the Union because the establishment feared a possible landslide victory for the anti-Union Commissioners. Instead 45 Commissioners were hand-picked to represent the whole country (see Scottish representatives to the first Parliament of Great Britain) as the first MPs from Scotland. 43 of these hand-picked representatives were pro-Union. From 1708, there were 45 single member constituencies of the Parliament of Great Britain. These constituencies remained unchanged until 1832. All the burghs were grouped into 4- or 5-member districts, apart from Edinburgh. Three pairs of shires were represented in alternate Parliaments. The names given in the 'Shire or Stewartry' column in the list below were those for the shires and stewartries used in the Parliamentary returns for the Estates of Scotland which met on 6 May 1703, as reported in 1878 (this reporting date is important to note, as the names used are the anglicised ones introduced by the Victorians, and not the names given to the subdivisions of Scotland extant
