World War II: French monarchist, Fernand Bonnier de La Chapelle, assassinates Vichy French Admiral François Darlan in Algiers, Algeria.

Monarchism in France is the advocacy of restoring the monarchy in France, which was abolished after the 1870 defeat by Prussia, arguably before that in 1848 with the establishment of the French Second Republic. The French monarchist movements are roughly divided today into three groups:

1. The Legitimists for the royal House of Bourbon,
2. the Orléanists for the cadet branch of the House of Orléans, and
3. the Bonapartists for the imperial House of Bonaparte

Fernand Bonnier de La Chapelle was a royalist member of the French Resistance during World War II. He assassinated Admiral of the Fleet François Darlan, the former chief of government of Vichy France and the high commissioner of French North Africa and West Africa, on 24 December 1942.

Vichy France, officially the French State, was a French rump state headed by Marshal Philippe Pétain during World War II, established as a result of the French capitulation after the defeat against Germany. It was named after its seat of government, the city of Vichy.

Jean Louis Xavier François Darlan was a French admiral and political figure. Born in Nérac, Darlan graduated from the École navale in 1902 and quickly advanced through the ranks following his service during World War I. He was promoted to rear admiral in 1929, vice admiral in 1932, lieutenant admiral in 1937 before finally being made admiral and Chief of the Naval Staff in 1937. In 1939, Darlan was promoted to admiral of the fleet, a rank created specifically for him.
