The question of nationality and nationalism has been a central feature of political debates on the Left. During the French Revolution, nationalism was a policy of the Republican Left.  The Republican Left advocated civic nationalism  and argued that the nation is a "daily plebiscite" formed by the subjective "will to live together". Related to "revanchism", the belligerent will to take revenge against Germany and retake control of Alsace-Lorraine , nationalism was sometimes opposed to imperialism . In the 1880s, there was a debate between those, such as Georges Clemenceau (Radical), Jean Jaurès (Socialist) and Maurice Barrès (nationalist), who argued that colonialism diverted France from the "blue line of the Vosges " (referring to Alsace-Lorraine), and the " colonial lobby ", such as Jules Ferry (moderate republican), Léon Gambetta (republican) and Eugène Etienne , the president of the parliamentary colonial group. After the Dreyfus Affair however nationalism became increasingly associated with the far right.
