The French Mission was organized 18 June 1850. It was closed in 1864, though missionary work did continue under the direction of the other missions in Europe. On 15 October 1912 the mission was reorganized, but it was closed two years later, on 18 September 1914, due to the outbreak of World War I. A few years after the war, the French Mission was reorganized from the Swiss-German Mission and the Netherlands Mission in December 1923. It remained open until World War II, closing on 14 December 1939 due to the war. On 23 April 1946 the mission reopened once again.
