Sikhism originated in northern India over 500 years ago and is now one of the largest organized religions in the world with over 20 million adherents. It was founded by Guru Nanak and nine subsequent gurus who established the religion's core beliefs, practices, and scripture. Sikhism teaches the oneness of God, equality of all people, engaging in charitable acts, honest work, and living a virtuous life. Some of the most distinctive practices for Sikhs include keeping uncut hair wrapped in a turban, carrying a small knife, wearing a steel bracelet, and visiting the Golden Temple in Amritsar, India which is the religion's most sacred site.
