Dravia Nadu defintiely might work for what I would want to do. How Though could we divide it up into more? Like only a bit more, though maybe a unified one could still work.
An independent Karnataka/Mysore is possible, as is Kerala, as is Tamil Nadu, or a Telugu state. With the country being founded by language-based nationalism, it makes sense that it results in the rise of language-based nationalism within the new country.
How about for northern and Western India?
Sindh is possible, as is the Northwest Frontier Province and Balochistan. IOTL, there is an active Sindhi nationalism, a massive Balochi insurgency, and the North West Frontier Province tried to secede even IOTL.
As for anything more, maybe you could get some of the princely states in Uttarakhand and Himachal Pradesh to secede, but I’m not sure how. Uttarakhand seems likelier than Himachal, anyways.
The Hindi belt forming its own countries is just plain ASB, as it is unified in language, culture, and geography.
And wonder if we could still maybe do something with Punjab... maybe they form a union with Sindh and Kashmir...?
That just sounds like a larger version of Pakistan. Rather boring, if you ask me.
