In the second half of the twentieth century, Louviers' political history has a left-wing tilt. From 1953–1958, the mayor was Pierre Mendès France (1907–1982), a member of the left-wing Radical Party. From 1965–69, the mayor was Ernest Martin of the DVG (Miscellaneous left). The candidates on the list that he headed were left-wing and anti-authoritarian; their party allegiances went from the Parti Socialiste Unifié (PSU) to the anarchists. They sought self governance ("autogestion"), and the events of May 1968 led in Louviers to the establishment of self-managing bodies – neighbourhood committees, avant-garde cultural policies, and so on.
