François Eliès, born Fañch Eliès and better known by the pseudonym Abeozen, (1896 Saint-Sauveur, Finistère – 1963 La Baule) was a Breton nationalist, novelist and dramatist who wrote in the Breton language. Abeozen was also a noted scholar of the Welsh language. As France was liberated Abeozen, like many Breton nationalists, was arrested for collaborating with the German occupants and spent fourteen months in prison. (See also Breton nationalism and World War II for the political background.) He was further fired from the Éducation nationale and forbidden to stay in administrative Brittany.
