The following outline is provides an overview of Sikhism, or Sikhi (its endonym). Sikhism is a monotheistic religion—emphasizing universal selflessness and brotherhood—founded in the 15th century upon the teachings of Guru Nanak and the ten succeeding Gurus. It is the fifth-largest organized religion in the world, and one of the fastest-growing.
