India and Khan Mohammad Atif, a professor at the University of Lucknow, estimates that "The population of Pathans in India is twice their population in Afghanistan". Historically, Pashtuns have settled in various cities of India before and during the British Raj in colonial India. These include Bombay (now called Mumbai), Delhi, Calcutta, Rohilkhand, Jaipur and Bangalore. The settlers are descended from both Pashtuns of present-day Afghanistan and Pakistan (British India before 1947). In some regions in India, they are sometimes referred to as Kabuliwala. In India significant Pashtun diaspora communities exist. While speakers of Pashto in the country only number 21,677 as of 2011, estimates of the ethnic or ancestral Pashtun population in India range from 3,200,000 to 11,482,000 to as high as double their population in Afghanistan, as claimed by former Head of Department of Persian at Lucknow University, India. The Rohilkhand region of Uttar Pradesh is named after the Rohilla community of Pashtun ancestry. They also live in the states of Maharashtra in central India and West Bengal in eastern India that each have a population of over a million with Pashtun ancestry; both Bombay and Calcutta were primary locations of Pashtun migrants from Afghanistan during the colonial era. There are also populations over 100,000 each in the cities of Jaipur in Rajasthan and Bangalore in Karnataka. Bombay (now called Mumbai) and Calcutta both have a Pashtun population of over 1 million, whilst Jaipur and Bangalore have an estimate of around 100,000. The Pashtuns in Bangalore include the khan siblings Feroz, Sanjay and Akbar Khan, whose father settled in Bangalore from Ghazni. During the 19th century, when the British were accepting peasants from British India as indentured servants to work in the Caribbean, South Africa and other far away places, Rohillas who had lost their empire and were unemployed and restless, were sent to places as far as Trinidad, Surinam, Guyana, and Fiji, to work with other Indians on the sugarcane fields and perform manual labour. Many of these immigrants stayed there and formed unique communities of their own. Some of them assimilated with the other South Asian Muslim nationalities to form a common Indian Muslim community in tandem with the larger Indian community, losing their distinctive heritage. Some Pashtuns travelled to as far away as Australia during the same era. Today, the Pashtuns are a collection of diversely scattered communities present across the length and breadth of
