While looking for maps of the Sikh Empire on Google Images, I found some... interesting South Asian irredentist maps.
First off we have some kind of Sikh wank, which, if this were an actual country, would be heavily Hindu and Muslim, which I would think rather negates the purpose of a Sikh country.
Next up we have Pakistan growing tentacles into a broken India, but oddly enough not retaking Bangladesh. What becomes of Sikkim, Assam, the Andamans and Nicobars, Manipur etc.? No clue, maybe they all go independent.
another thrilling Sikh wank, this time adding a bunch of Buddhist regions to increase the not-Sikh-ness of this Sikh Empire.
a religiously balkanized India that doesn't even name most of its countries and for some reason gives all of Rajasthan and Gujarat to the Jains (are there a lot of Jains there? Im not really sure. Probably not enough to justify giving them that whole thing, though.)
