Founder of Sikhism is Guru Nanak.

Guru Nanak (15th April 1469 – 22nd September 1539) was the first of the ten Sikh Gurus.

He was born in Rai Bhol Ki Talavandi (present-day Nankana Sahib, Punjab, Pakistan). Guru Nanak’s birth anniversary is celebrated as Guruparb every year. This festival of Sikhs is celebrated worldwide on the full moon day (Kartik Pooranmashi) in the month of Katak, October-November. Guru Nanak’s teachings are registered in the holy scripture of Guru Granth Sahib in the form of 974 poetic hymns. “Asa di Var”, “Japji Sahib” is some of the prayers by Guru Nanak that are registered in the Holy Scripture.

Guru Nanak is regarded as the greatest religious innovators of all time. Guru Nanak was succeeded by Guru Angad (born as Bhai Lehna on 31st March 1504 and passed away on 29th March 1552). Guru Nanak passed away in Kartarpur, Mughal Empire (present-day Pakistan) at the age of 70.
