The International Fellowship of Reconciliation was founded on the eve of World War I by a British Quaker (Henry Hodgkin) and a German chaplain to the Kaiser (Friedrich Siegmund-Schultze), who refused to let the impending hostilities threaten their friendship. Their Christian opposition to war and desire to build a new and better world launched a civil society organization that has worked for peace and nonviolence around the world for over 90 years. It has many international chapters that have played prominent roles in nonviolent campaigns, including the U.S civil rights movement and training and support for the Philippines People Power movement. In the 1940s, member André Trocmé helped save thousands of Jews from the Nazi Holocaust.
