The word Bhangi is derived from bhang or hemp, a plant of wild growth found in the jungles of the Punjab, and in abundance along river banks. When pounded in a mortar with a pestle and sifted through a piece of coarse cloth, it leaves behind a thick liquid of gree colour. Its drink is intoxicating and soothes the effect of heat in summer. A particular group of Dal Khalsa liberally indulged in this drink, and profusely entertained others with it. At the time of fighting, it made its lovers furious and reckless. On account of addiction to it, this group of Khalsa came to be called Bhangi. This misal was the largest in its size and area it occupied.
This nom de plume attracted the sweeper class also called Bhangi to join them. They were freely welcomed by this band of the Khalsa among them. Some of them were offered important posts. Although the majority of the soldiers of Bhangi misls were Jats, there were substantially number of converted sikhs from lower hindu castes. Here are the name of some of the pioneer Sardars of Bhangi Misal:
Chajja Singh: of village Panjwar, 13 kms from Amritsar. He took pahul from the hand of Guru Gobind singh ji and got many Sikhs from the Majha area to join his band.
