A monotheistic religion founded in 1469 by Guru Nanak. The religion was led by a series of ten gurus until the last declared that the Guru Granth Sahib (the collected holy scripture, written by the ten gurus) was the last guru, and the only one the people would ever need. Includes ideas of reincarnation based on deeds but also the forgiveness available from God, the rejection of idolatry and the caste system, and the belief that the work of God can be seen in all his creation.

The customary headgear of Sikh men is a turban, symbolising equality and denial of caste and also helping to keep their hair in order. (Many Sikhs will not cut their hair: if God chose that humans should grow hair, then it is good in His sight, so why should humans cut it off?)

Another token of Sikhism is the Kirpan.
