Siol nan Gaidheal ([ˈʃiəl̪ˠ nə ˈŋɛː.əl̪ˠ], meaning "Seed of the Gaels") is a minor Scottish ultranationalist[4] and ethnic nationalist group which describes itself as a "cultural and fraternal organisation".

[1] It grew in the immediate aftermath of the 1979 devolution referendum, despite being shunned by the mainstream nationalist SNP, whose ruling executive attempted to ban SnG from the party as early as 1980.

[12] Throughout the 1980s, Siol nan Gaidheal published a magazine called Firinn Albannach [sic][a] (Scottish Truth), which has been described as having a rhetoric which was "anti-communist, neo-fascist and sometimes violent in tone".

[13] Prime Minister Margaret Thatcher's personal security was stepped up in Scotland after members of SnG tried to accost her outside the Conservative Party conference in Perth in 1982.

[14] Some members of SnG formed an unofficial paramilitary wing called Arm nan Gaidheal (AnG; "Army of the Gael"), which was responsible for a number of petrol bomb attacks in 1982 and 1983.

[3] The group made headlines in the run-up to the referendum for heckling Labour MP Jim Murphy on his visits to Dundee and Montrose.

SnG exists to promote, safeguard and stimulate a third Scottish Renaissance which will use the best past traditions of Scotland to forge a new Nation which will be an example to the world.They have been branded as like "proto fascists" by former SNP leader Gordon Wilson.
