Write about the rayas and nayakas

The rayas and the nayakas:

1. Nayakas were military chiefs who usually controlled forts and had armed supporters. They moved from one area to another, and in many cases were accompanied by peasants looking for fertile land on which to settle. They usually spoke Telugu or Kannada. Many nayakas submitted to the authority of the kings of Vijayanagara but they often rebelled and had to be subdued by military action.
2. The amara-nayaka system was a major political innovation of the Vijayanagara Empire. They were military commanders who were given territories to govern by the raya. They collected taxes and other dues from peasants, craftspersons and traders in the area.
3. These contingents provided the Vijayanagara kings with an effective fighting force with which they brought the entire southern peninsula under their control.
