History of the Maratha nation

<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->It is known from an edict that the Reddy's who were once of professions of a different Varna became Kshatriyas. A 1345 inscription of Reddi kings read, "With the death of the Kshatriyas (by the Muslims - I think the word used to describe the invaders in the edict was Mlecchas), the duty of defending cows and Brahmins fell to Shudras". The Reddys then bravely fought off the Muslims. <!--QuoteEnd--><!--QuoteEEnd-->
True, I think you are referring to Vema Reddy, he along with Prolaya Nayaka and Kapaya Nayaka liberated many parts of Andhra Pradesh from Muslims and his inscriptions talk in a similar vein of what you said, for example one of them says:
<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->In 1325 the responsibility of organizing defense of the dharma was taken up by the valiant shudra warrior Prolaya Vema Reddy. Son of local warlord, he describes himself "as one of the 4th varNa that emerged from the feet of mahAviShNu" who decided to rid the land of the wicked Turks after kshatriyas had all been killed for the protection of the agrahAras and brAhmaNas.
