In 1865 he persuaded the then Bishop of Quimper and Leon, Monseigneur Sergeant, of the value of a newspaper written in the Breton language for the inhabitants of the diocese.
He also encouraged Sergeant to entrust the journal to Goulven Morvan, priest of Tréhou, who spoke excellent Breton and had wide experience in a number of local parishes.
The review ceased publication on April 26, 1884, its last editor (1883 to 1884) being Gabriel Milin, a lay Breton language author, who had taken over from abbé Nédélec.
Thanks to the activity of the Feiz ha Breiz Association, which was set up in the Diocese of Quimper and Leon to protect the Breton language, the review was revived in 1899.
After Perrot was assassinated by the Resistance, the journal continued for a short while, but its last number appeared in March 1944, edited by abbé L. Bleunven, Rector of Ploudalmezeau.
