This was set up because of the creation of the extremist Breton National Party, which had pro-Nazi sympathies.
In 1936, he, Morvan Marchal, and Francis Bayer du Kern founded Kredenn Geltiek Hollvedel (Worldwide Celtic Beliefs), also known as Kevanvod Tud Donn and Dêua Ana.
In addition, he also founded a journal about druidic studies and philosophy called Kad (combat).
Through the movement he sought to commemorate Breton national heroes, and was responsible for the statue of Nominoë, the first independent Duke of Brittany, at Bains-sur-Oust.
He also designed the commemorative plaque[2] for the 18th century Breton rebel Marquis de Pontcallec in the Place du Bouffay, in Nantes.
