Unified India?

 

The modern state of India is more of an artificial creation establishmed by the departing British Colonialist who connected and integrated vasts swathes of territory and different peoples/cultures/ethnic groups into one new new nation called India, In essence, they can be credited with creating Indian's current national indentity and country, which is good from an economic point of view (but bearing in mind Colonial intentions, which more accurately reflected their personal requirements), but bodes poorly for regional culture and identity, many of whom are being diluted as we speak.

 

historically speaking, parts of India where often conquered by foreign invading forces and joined to their expanding empires.

 

One exception may also be the short rule of Ashoka, who was a buddhist and ruled over a vast array of lands in the region.  But his rule is an exception rather than the rule.

 

Other than that, the South Asian region particularly the areas of modern day India, where ruled by a plethora of different kings, 'governments' who operated freely and independently of each other. 

 

I would recommend reading up from different sources to help broaden your understanding of the region as a whole in order to see the regions history in its broader sense to fully understand it.

 

Wishing you well in your endeavours.
