As he was connected with the nonconformist intellectual movement of Santiago, the new archbishop made him be banished and locked in 1803 in Aniago Monastery (Valladolid). In 1809, he organised in Seville the Galician revolt against the French. He participated in the reconquest of Vigo, where he was nominated as political governor and during the Assembly of Cadiz he defended the liberal laws.
