Far-right leagues rally in front of the Palais Bourbon in an attempted coup against the French Third Republic, creating a political crisis in France.

The far-right leagues 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.

The Palais Bourbon is the meeting place of the National Assembly, the lower legislative chamber of the French Parliament. It is in the 7th arrondissement of Paris, on the Rive Gauche of the Seine across from the Place de la Concorde. The official address is on the Rue de l'Université, facing the Place du Palais-Bourbon.

A coup d'état, or simply a coup, is typically an illegal and overt attempt by a military organization or other government elites to unseat an incumbent leadership. A self-coup is said to take place when a leader, having come to power through legal means, tries to stay in power through illegal means.

The French Third Republic was the system of government adopted in France from 4 September 1870, when the Second French Empire collapsed during the Franco-Prussian War, until 10 July 1940, after the Fall of France during World War II led to the formation of the Vichy government. The French Third Republic was a parliamentary republic.
