Rohillas are a mixed Indian community of Pashtun heritage, historically found in Rohilkhand, a region in the state of Uttar Pradesh, India. It forms the largest Pashtun diaspora community in India, and has given its name to the Rohilkhand region. The Rohilla military chiefs settled in this region of northern India in the 1720s, the first of whom was Ali Mohammed Khan.
