Tweeddale was also a historic district of Scotland, bordering Teviotdale and the Marches to the east, Liddesdale and Annandale to the south, Clydesdale to the west and Lothian to the north. The district which covered the Sheriffdoms of Peebles and Selkirk later became of the County of Peebles in the north and County of Selkirk or the "Ettrick Forest" in the south, two of the counties of Scotland. The main reorganisation took place during the Local Government (Scotland) Act 1889, this Act established a uniform system of county councils and town councils in Scotland and officially restructured many of Scotland’s counties.
