The fall of France in June 1940 served as the direct catalyst for the formation of the Free French movement. Following the military collapse of Metropolitan France, the government was transferred to Marshal Philippe Pétain, who sought an armistice with Germany.1

Opposing this surrender, General Charles de Gaulle fled to London and issued a radio appeal on June 18, 1940, urging his compatriots to continue the war against Germany. This act of defiance established the foundation for the Free French Forces, initially composed of French troops already in England, volunteers, and naval units.12

While de Gaulle initially faced significant political challenges and lacked widespread recognition, his movement grew as various French colonial territories rallied to his cause and underground Resistance groups within France began to align with his leadership. By positioning himself as the leader of the continuation of the war, de Gaulle transformed a small group of exiles into a movement that eventually unified French forces to participate in the liberation of France.12
