"Rama and Ayodhya" and "The Battle for Rama", by Meenakshi Jain
Circumstantial Evidence Preceded Archaeological Evidence(see my earlier review of Rama and Ayodhya and a part-review of The Battle for Rama
This review incorporates material from both reviews as well)
The diffusion of propaganda requires repetition. In the words of someone many leftists have secretly admired for long, repetition is what makes propaganda successful (the full quote is (bold-emphasis mine), "The most brilliant propagandist technique will yield no success unless one fundamental principle is borne in mind constantly and with unflagging attention. It must confine itself to a few points and repeat them over and over".
This was a strategy used to brilliant success by militant Islamists, communist historians, and Indologists of dubious integrity in the west during the Ayodhya movement in the 1980s and 90s.
