NIRANKARIS, a sect of the Sikhs born of a reform movement which arose in northwest Punjab in the middle of the nineteenth century aiming to restore the purity of Sikh belief and custom. Its founder, Baba Dayal (1783-1855), was a contemporary of Maharaja Ranjit Singh. A man of humble origin, he cavilled at the shortcomings of the mighty and assailed the rites and observances which had perverted the Sikh way of life. His main target was the worship of images against which he preached vigorously.
