Sikhism originated in 15th-century Punjab, Delhi Sultanate (present-day India and Pakistan) with the teachings of Nanak and nine successive gurus. The principal belief in Sikhism is faith in Vāhigurū— represented by the sacred symbol of ēk ōaṅkār [meaning one god]. Sikhism's traditions and teachings are distinctly associated with the history, society and culture of the Punjab. Adherents of Sikhism are known as Sikhs (students or disciples) and number over 27 million across the world.[citation needed]
