The far-right leagues (French: ligues d'extrême droite) were several French far-right movements opposed to parliamentarism, which mainly dedicated themselves to military parades, street brawls, demonstrations and riots. The term ligue was often used in the 1930s to distinguish these political movements from parliamentary parties. After having appeared first at the end of the 19th century, during the Dreyfus affair, they became common in the 1920s and 1930s, and famously participated in the 6 February 1934 crisis and riots which overthrew the second Cartel des gauches, i.e. the center-left coalition government led by Édouard Daladier.
For a long time, the French left wing had been convinced that these riots had been an attempted coup d'état against the French Republic. Although contemporary historians have shown that, despite the riots and the ensuing overthrow of the governing left wing, there had been no organized plans to overthrow Daladier's Radical-Socialist government, this widespread belief led to the creation of the anti-fascist movement in France, and later to the dissolving of these leagues in 1936 by the leftist Popular Front government headed by Léon Blum.
