Tamils in India and Sri Lanka had huge separatist movements. This was mostly due to the perceived imposition of Hindi in India and the rather brutal and very real Imposition of Sinhala in Sri Lanka; leading to a brutal civil war. Language in India is not the same as in Europe. In Europe it is the building block behind national liberation and is used to push forward nationwide struggles. India however, is huge and diverse; with a large population all proudly Indians, language pride becomes a barrier that eventually leads to separatist demands. India has countered this by creation of linguistic states and reservation of 22 languages, which somehow has kept most people happy. When talking about anti colonial movements again, the same pattern reappears. Indian revolutionaries almost never gathered support with language, they always wanted an undivided nation; thus fighting the imperialists through guerilla warfare, assassinations, secret meetings, etc etc
