Answer:
Guru Nanak was the founder of the Sikh religion.
Guru Nanak was born to Mata Tripta Ji and Kalyan Chand Das Bedi Ji (often shortened to Mehta Kalu) on Nov. 29, 1469 in Rai Bhoi di Talwandi (now Nankana Sahib, Pakistan). Guru Nanak had an older sister named Bebe Nanki Ji. At age seven, Guru Nanak was enrolled in the village school, where he was said to have noted the spiritual significance of the number “one” as in one God, or Ik Onkar (ੴ). Guru Nanak stood up for rights of all people no matter what caste, religion, gender, or nationality. Guru Nanak Ji taught three important principles:
Kirat Karo - Work Hard and earn an honest living.
Naam Japo - Remember God.
Vand Chhako - Help others in need.
Between 1500 and 1524, spanning 24 years, Guru Nanak traveled more than 28,000 km and spread his message of equality throughout much of Asia and parts of Europe and Africa.
In a time when people were segregated by caste and women were not given the same rights as men, Guru Nanak denounced the caste system, and elevated the status of women as equal to men. Guru Nanak acquired many followers, the most important being Bhai Mardana Ji, his lifelong companion in all his travels. Guru Nanak Dev JI started a tradition called Langar, which is free food served to all people without making a distinction of religion, caste, gender, economic status, or ethnicity. Langar is still served in Gurdwaras (Sikh places of worship) today. People sit and eat together, and the kitchen is maintained by community volunteers.
