History for IAS – Extent of Mauryan Empire

In the previous post, we saw the family tree of the Mauryan dynasty. In this post we will explore the reign of its three major rulers – Chandragupta, Bindusara and Ashoka. I have highlighted the important points that you should remember while preparing for Prelims as questions are likely to be asked on these aspects.
