Sikhism is a monotheistic religion founded in the 15th century by Guru Nanak in the Punjab region of India. It emphasizes devotion to one God, equality among all people, and selfless service to humanity. The religion is rooted in the teachings of ten Sikh Gurus, as compiled in the Guru Granth Sahib, the Sikh holy scripture.

Core principles include living an honest life, remembering God at all times, and sharing with those in need. Sikhs reject caste divisions and rituals, focusing instead on inner devotion and moral conduct. The community kitchen, or langar, symbolizes equality and generosity.
