In his memoirs, published in 1933, Schwerer states that he rejected the French Third Republic in favour of royalism at an early age.^[6] After his retirement in 1924 Schwerer devoted himself to the royalist League of the Action francaise, becoming one of the movement's most active leaders. He became president of the League in 1930, succeeding Bernard de Vésins in difficult circumstances. He was a talented orator.^[1] At the December 1931 congress, "greeted by loud acclamation", he gave a full presentation of "the general situation of France", external, financial, economic, interior and religious. He concluded with a passionate statement,^[7]

... the situation is very dark. It would be almost desperate if there were not a cell that is not huge, but that is alive and is the only one able to animate the amorphous environment that surrounds it. This cell is the Action française. Every day more people understand it. There will always be imbeciles in France, men of bad faith, madmen and criminals; but there are in our midst many excellent elements now deceived and blinded. Our task is to enlighten them and then to train them to the assault. It requires a huge effort pursued with perseverance. The job is tough. We will not do it by sitting in a good armchair, in flowery salons, lavishing sweet smiles and honeyed words, fighting in white gloves with dainty foils. We must be ready for hard sacrifices. Are you all ready? You want the restoration of the Monarchy. Have you all done what is necessary to achieve this?^[7]

Antoine Schwerer was forced by illness to retire to Brittany in 1935. He was succeeded as head of the League by François de Lassus.^[7] He died in Grand-Fougeray, Ille-et-Vilaine, on 3 November 1936.^[8]
