There are over 20 million Sikhs on the planet, many of whom live in the Punjab area of India. The 2001 census recorded that there were 336,000 Sikhs living in the United Kingdom.
Sikhism was founded in the 1500s in the Punjab area of what is now India and Pakistan. It was set up by Guru Nanak and is founded on his teachings, and those of the nine Sikh leaders who followed him.
The most important thing in Sikhism is the internal religious state of the individual.
