The French State, known as Vichy France, proclaimed by Marshal Philippe Pétain after the Fall of France in 1940 before Nazi Germany, was quickly recognized by the Allies, as well as by the Soviet Union, until 30 June 1941 and Operation Barbarossa. However France broke with the United Kingdom after the destruction of the French Fleet at Mers-el-Kebir. Canada maintained diplomatic relations until the occupation of Southern France (Case Anton) by Germany and Italy in November 1942.
