Sources of information

Information about Ashoka from his inscriptions; other inscriptions that mention him or are possibly from his reign; and ancient literature, especially Buddhist texts. These sources often contradict each other, although various historians have attempted to correlate their testimony.

Inscriptions

Ashoka's inscriptions are the earliest self-representations of imperial power in the Indian subcontinent. However, these inscriptions are focused mainly on the topic of dhamma, and provide little information regarding other aspects of the Maurya state or society. Even on the topic of dhamma, the content of these inscriptions cannot be taken at face value. In the words of American academic John S. Strong, it is sometimes helpful to think of Ashoka's messages as propaganda by a politician whose aim is to present a favourable image of himself and his administration, rather than record historical facts.

A small number of other inscriptions also provide some information about Ashoka. For example, he finds a mention in the 2nd century Junagadh rock inscription of Rudradaman. An inscription discovered at Sirkap mentions a lost word beginning with "Priyadari", which is theorised to be Ashoka's title "Priyadarshi" since it has been written in Aramaic of 3rd century BCE, although this is not certain. Some other inscriptions, such as the Sohgaura copper plate inscription and the Mahasthan inscription, have been tentatively dated to Ashoka's period by some scholars, although others contest this.
