Which two are you referring to? The first separatist movement of course was the demand for Pakistan prior to independence. Then there was the demand for Bangladesh in East Pakistan. Both of these were successful.
Within today's India, there was first Tamil separatism, then Sikh, Kashmir and then a few small eastern tribal groups. They have each waxed and waned over the years for different reasons. Ultimately it is the duty of the Indian state to preserve & strengthen the Union while ensuring that its value for each constituent outweighs any ethnic or religious separatist sentiments.
The US is unique in being formed basically from scratch, and growing from there, rather than as a merger of historical nation/states.
I was referring to what you referenced. In a lot of ways the US was just another part of England, but the revolution really started as people wanting their rights as English citizens and went separatists from there. We then got waves to different regions as immigrants (e.g. the North Dakota and Minnesota immigration maps are pretty interesting for an example).
It just seemed like our Civil War shutdown the separatists and India separatists had some success, so I was wondering if there is a likely further break or not.
