The Nation of Islam (NOI) is a religious and political organization founded in the United States by Wallace Fard Muhammad in 1930. A black nationalist organization, the NOI focuses its attention on the African diaspora, especially on African Americans. While describing itself as Islamic, its religious tenets, while phrased in Islamic terminology, differ considerably from mainstream Islamic traditions. Scholars of religion characterize it as a new religious movement. It operates as a centralized and hierarchical organization.
