 The Act of Union 1707 made this function redundant, but a Lord High Commissioner to the General Assembly of the Church of Scotland has been appointed each year, as the Sovereign's personal representative, since 1690.Prior to 1929, the General Assembly was held in the former Tolbooth Highland St John's Church on Edinburgh's Royal Mile (this building is no longer used as a church, instead being converted into "The Hub" for the Edinburgh International Festival society), where a Throne was provided for the use of the Lord High Commissioner.The union of the Church of Scotland and the (non-established) United Free Church of Scotland took place in 1929.
