Traditionalism or traditionalist Islam, in the context of Muslim society in Indonesia, refers to a religious strand which puts emphasis on preserving traditionally established local rituals and scholarship. Traditionalist Muslims refer to themselves as ahlusunnah wal jamaah or aswaja. Traditionalism is often contrasted with modernism, which is inspired by modernity and rationalism. Traditionalism has been the most adhered Muslim religious orientation in the history of contemporary Muslim Indonesia. The extent of traditionalism widely overlaps with the influence of a socio-religious organization Nahdlatul Ulama, the biggest Muslim organization in Indonesia. Traditionalism is also a critical element within the Muslim intellectual movement known as Islam Nusantara.
