With a POD no earlier than the end of WW1, your challenge is to come up with a plausible TL in which the British Raj falls apart even more than IOTL, and gets balkanized into as many different independent nations as possible by the present day. IOTL, it was effectively broken up into six nations- India, Pakistan, Myanmar, Bangladesh, Yemen and the UAE. So then, here are the requirements for the different difficulty bands in this AHC:
Tin- Balkanize the former territories encompassed by the British Raj, as of November 1918, into at least 10 independent sovereign nations by the present day
Bronze- Balkanize the former territories encompassed by the British Raj, as of November 1918, into at least 16 independent sovereign nations by the present day
Silver- Balkanize the former territories encompassed by the British Raj, as of November 1918, into at least 25 independent sovereign nations by the present day
Gold- Balkanize the former territories encompassed by the British Raj, as of November 1918, into at least 40 independent sovereign nations by the present day
Platinum- Balkanize the former territories encompassed by the British Raj, as of November 1918, into at least 55 independent sovereign nations by the present day
Big no-no's: nuclear exchanges, ASB intervention, plague epidemics and natural disasters which didn't happen IOTL. And annexations of former British Raj territory by other nations (e.g, Aksai Chin's effective annexation by China) don't count towards increasing the total. Anyone up to the challenge? And what's the highest AHC difficulty level that you think you could realistically clear?
