The Nayak System of administration was one of the key elements of the Vijayanagar Empire which protected South India and Sri Lanka against the Turkic invaders for almost 300 years. The origin of the Nayak System dates back to the Kakatiya Period. It was developed by Queen Rudramadevi and her successor Prataparudra.

I would like to know wheather the different social movements, which emerged in south India before and during the Kakatiya period like the Bhakti movement, had an influence on the Kakatiya rulers to establish this unique system. In fact the Nayak System of the Kakatiya period reduced the power of the nobles and even allowed people from lower classes to become governors.
At that time there were only few regions in South Asia or even in the world where such a small part of the kingdom was under the rule of feudal lords and instead large parts of the Kakatiya Dynasty were under the rule of the Nayak governors who were appointed by the Kakatiya rulers.

Did the great Social reformers like Basava of that time, who propagated the equality of all classes and castes, had an impact on the Kakatiya rulers to establish this system or were there other factors which led to the Nayak System?
