How can we, with a PoD of 185 BCE or later, (the historical fall of the Mauryan dynasty) maintain a legacy of either a united India and a Buddhist India?
Both of these are perhaps the Mauryan's most famous contributions to Indian history– they were not merely the first empire to come close to uniting India, they were the first great Indian Empire, and the last to come close to uniting India until the Mughals. Additionally, under Ashoka, the Empire was famously converted to Buddhism. So how can we prevent a Buddhist decline and aid in a United Indian subcontinent?
