During the later half of the 15th century, Punjab gave birth to a great person who brought not only the Punjab but also the whole of India out of darkness. This great person was Guru Nanak Dev. The political, social and religious condition of Punjab was extremely bad during Guru Nanak Devs time. To eliminate the evils, Guru Nanak Dev waged a peaceful struggle. The revolutionary change that took place in India with Guru Nanak Devs struggle of 70 years personified as Sikh religion .
Though the Sikh religion chose a peaceful path for religious and social reform, but the Sikhs adopted the policy of arms after some time. Guru Hargobind was first to adopt the policy of armed struggle . Guru Arjun Devs martyrdom was the reason for this change because the emperor Jahangir, due to his orthodoxy, could not tolerate the increasing influence of the Sikh religion. The Mughal emperors wanted to see only the Islam religion throughout India, therefore, Guru Arjun Dev was executed on 30th May, 1606 .
