French declaration of war on Germany (1939)

Newspaper Paris-soir announcing France's declaration of war on Germany on 3 September 1939.

On 3 September 1939—two days after the German invasion of Poland—France declared war on Nazi Germany according to its defensive treaty with Poland, when France's ultimatum to Germany, issued the previous day, expired at 17:00. This occurred hours after the United Kingdom declaration of war on Germany.[1][2]
