Prompted by international ramifications of Jewish migration from Nazi Germany, President Franklin D. Roosevelt called a world conference on refugees in March 1938. The conference, held at Evian, France, in July, established the Intergovernmental Committee on Political Refugees. The committee, led by American diplomats, sought relaxation of Germany's discriminatory practices against Jews and tried, without success, to resettle German Jews abroad. World War II ended the committee's efforts to achieve systematic immigration from Germany. The American, British, and German diplomatic papers contain the most thorough chronicle of American involvement in the refugee crisis. Memoirs and presidential public papers provide insight into Roosevelt's motivations for calling the conference. Although efforts to rescue German Jews failed, the refugee crisis introduced Americans to intervention in Europe.
