The 6 February 1934 crisis was an anti-parliamentarist street demonstration in Paris organized by multiple far-rightist leagues that culminated in a riot on the Place de la Concorde, near the building used for the French National Assembly. The police shot and killed 17 people, nine of whom were far-right protesters. It was one of the major political crises during the Third Republic (1870–1940). Leftist Frenchmen claimed it was an attempt to organize a fascist coup d'état. According to historian Joel Colton, "The consensus among scholars is that there was no concerted or unified design to seize power and that the leagues lacked the coherence, unity, or leadership to accomplish such an end."

The Place de la Concorde is one of the major public squares in Paris, France. Measuring 7.6 ha in area, it is the largest square in the French capital. It is located in the city's eighth arrondissement, at the eastern end of the Champs-Élysées.
