World War II: French Resistance coup in Algiers, in which 400 civilian French patriots neutralize Vichyist XIXth Army Corps after 15 hours of fighting, and arrest several Vichyist generals, allowing the immediate success of Operation Torch in Algiers.

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The French Resistance was a collection of groups that fought the Nazi occupation and the collaborationist Vichy regime in France during the Second World War. Resistance cells were small groups of armed men and women who conducted guerrilla warfare and published underground newspapers. They also provided first-hand intelligence information, and escape networks that helped Allied soldiers and airmen trapped behind Axis lines. The Resistance's men and women came from many parts of French society, including émigrés, academics, students, aristocrats, conservative Roman Catholics, Protestants, Jews, Muslims, liberals, anarchists, communists, and some fascists. The proportion of the French people who participated in organized resistance has been estimated at from one to three percent of the total population.

Algiers is the capital city of Algeria as well as the capital of the Algiers Province; it extends over many communes without having its own separate governing body. With 2,988,145 residents in 2008 and an estimated 3,004,130 residents in 2025 in an area of 1,190 square kilometres (460 sq mi), Algiers is the largest city in Algeria, the third largest city on the Mediterranean, sixth in the Arab World, and 29th in Africa. Located in the north-central portion of the country, it extends along the Bay of Algiers surrounded by the Mitidja Plain and major mountain ranges. Its favorable location made it the center of Ottoman and French cultural, political, and architectural influences for the region, shaping it to be the diverse metropolis it is today.
