The present study seeks to show that ever since its inception in 1699, the Khalsa movement possessed some of the major characteristics of a popular resistance movement, and that it further acquired all the characteristics of guerilla warfare in the post-Banda Bahadur period, 1716-68. It makes a small effort towards formulation of an Indian theory of peoples war, and provides the Indian students of guerilla warfare with a historical example of their own. Further it strives to show that the objective of Raj Khalsa which Guru Gobind Singh had placed before his Sikhs was fairly borad and capable of flexible interpretation. No doubt it was religious zeal which initially provided the accent and uncompromising style to Sikh struggle, the class nature of the Khalsa movement became fairly articulate when it progressively embraced socio-economic goals under Banda Bahadur. In mid-eighteenth century, when the Sikhs were unceasingly fighting for the twin objective of evicting the Mughals from the Panjab and preventing Afghan domination over it, their struggle acquired the nature and content of a popular Panjabi resistance movement which enjoyed active support of both the Hindus and the Muslims.
