World War II: The French armistice with Nazi Germany comes into effect.

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 Armistice of 22 June 1940, sometimes referred to as the Second Armistice at Compiègne, was an agreement signed at 18:36 on 22 June 1940 near Compiègne, France by officials of Nazi Germany and the French Third Republic. It became effective at midnight on 25 June. Signatories for Germany included Colonel General Wilhelm Keitel, head of the German armed forces (OKW), while those on the French side held lower ranks, led by General Charles Huntziger.
