Explanation:

Pindari, historically, an irregular horseman, plunderer, or forager attached to a Muslim army in India who was allowed to plunder in lieu of pay. The name is Marathi and probably derives from two words, meaning “bundle of grass” and “who takes.”
The Pindaris followed the Maratha bands who raided Mughal territory from the late 17th century. With the collapse of the Mughal Empire in the 18th century, these camp followers organized themselves into groups, each usually attached to one of the leading Maratha chiefs. But as those chiefs themselves grew weak at the end of the century, the Pindaris became largely a law unto themselves and conducted raids from hideouts in central India. The majority of their leaders were Muslims, but they recruited from all classes.
Lord Hastings after getting permission from the British government waged wars against the Pindaris which resulted in the Suppression of Pindaris.
