Founded in 1900, the IARF is the first international interfaith organisation - a worldwide community uniting diverse traditions of free and liberal religion. Our membership includes individuals and 48 organisations from 5 continents, 23 countries and various religious traditions, including Unitarianism, Christianity, Islam, Judaism, Buddhism, Shinto, Zoroastrianism, Hinduism indigenous faiths, and others. In nine countries we also have local chapters.

Our mission is to protect religious minorities, advance religious freedom and other human rights, and promote global awareness and understanding of liberating religion. We believe that religious freedom encompasses not only freedom of religion but also freedom within religion.

Our work spans diverse activities: from supporting projects and advocating with the UN and governments to organising courses, dialogues, and cultural exchanges. We strive to foster a global community of liberal thinkers who believe that free and liberal religion not only aids personal spiritual growth but also contributes to a more just world.
