Siol nan Gaidheal

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

The first incarnation of the group was founded by Tom Moore in 1978, though it became defunct twice and was re-established by Jackie Stokes in 1987 and again in 1997.

Though the group publicly disavows politics, SnG has been variously described by commentators as anywhere from "traditionalist" to "crypto-fascist" or "proto-fascist". Members of the group have been banned from membership of the mainstream nationalist Scottish National Party since 1982.
