In addition to political parties, other independent organisations promote the autonomy movement. The Revived Cornish Stannary Parliament was a human rights pressure group which claimed to be a revival of the mediaeval Stannary Parliaments, local legislative organisations in the mining regions. It was established in 1974 and had campaigned against the government of the United Kingdom's position on the constitutional status of Cornwall. The group has not been active since 2008. Other groups include TGG (Tyr-Gwyr-Gweryn), Cornwall 2000, Cornish Solidarity who were constitutional and Cornish human rights groups, but are no longer active, and the Cornish Constitutional Convention which campaigns for a Cornish Assembly.
