The origin of the Palayakkarar (poligari) system dates back to the 1530s. It is believed that this system was practiced earlier in Kakatiya kingdom of Warangal.  

• The literal meaning of Palayakkarar is the holder of a camp as well as the holder of an estate on military tenure.  
• Prior to the enforcement of this system Servaikarars and Talayaris collected fees for police work.  
• After the creation of palayams, the Servaikarars turned Palayakkarars and subordinated Talayaris to their authority.
