 The first major dialogue was the Parliament of the World's Religions at the 1893 Chicago World's Fair, which affirmed universal values and recognition of the diversity of practices among different cultures.The 20th century has been especially fruitful in use of interfaith dialogue as a means of solving ethnic, political, or even religious conflict, with Christian–Jewish reconciliation representing a complete reverse in the attitudes of many Christian communities towards Jews.Recent interfaith initiatives include A Common Word, launched in 2007 and focused on bringing Muslim and Christian leaders together, the "C1 World Dialogue", the Common Ground initiative between Islam and Buddhism, and a United Nations sponsored "World Interfaith Harmony Week".
