Abstract: Socialism history in Brittany is a shift from a mission land in a
Catholic region which voted for the right, to a political stronghold
built by the Socialist Party (PS). SFIO first relied upon the secular
republican culture until the fifties. Then, the United Socialist Party
(PSU) expanded the Socialist audience to include new social backgrounds,
thus renewing a political movement in crisis in the sixties, and
offering a springboard for a new generation of activists in the
1970s-1980s.
