http://en.wikipedia.org/wiki/Palnadu) provides a slice of Andhra history at the beginnings of Kakatiya empire. That battle is the most favorite subject for burrakatha (
http://en.wikipedia.org/wiki/Burrakatha).
The story highlights a lot of transitions:
- Kalachuris rule in PalnaduÂ
 * It was a transitional stage from Chalukayas to Kakatiya and establishment of pure Andhra/Telugu kingdom.
- Dominance of VeerashaivamÂ
 * On religious side, it is a fight between Shaivas and Vaishnavas on the land (karmarastram) where buddhism dominated leading to end of buddhism in Andhra. Nagamma supported shaivism where as Brahma Naidu is a follower of Chenna Kesava (so supporter of Vaishnawas)
- Rise and solidification of Nayaka castes
 * Although the battle is in between Kalachuris of same family to rule the palnadu, it is actually between two Nayakas - Nayaki Nagamma and Recherla Brahma Naidu
 * It also gives clues <b>into split of Kammas (belonging to Nagamma) and Velamas (belonging to Brahma Naidu)</b> and beginning of Nayaka system.
 * Kakatiya empire was a federation of 70+ Nayaka regions<!--QuoteEnd--><!--QuoteEEnd-->
It is interesting observation. Do you mean that current day castes Reddy, Velama, Raju, kamma and Kapu are all actually nayakas of bye-gone period?
I read in one of the blogs/articles ( may not be authentic ) somewhere that Kammas are actually migrants from current Multan area of Punjab(now in Paki land), an agrarian-enterprenural class imigrated during pre-Satavahana period. They went thru the economic downturn with everyone else before they turned back to thier current riches.<!--QuoteEnd--></div><!--QuoteEEnd-->
Current-day Reddys are amalgamation of various subcastes. Only some Reddy subcaste (e.g Kapus) are Nayaka castes. Reddy was a title but became a caste now. Current-day Kapus are also amalgmation due to political convenience. Not all current-day Kapus are original Kapus *. Only some subcastes are Nayakas. Other Reddy subcastes are either warriors, village heads, or farmers.
All Velama subcastes are Nayakas. Padmanayaka velamas are Doralu (kings) and Koppula Velamas are warriors.
Many Kamma subcastes are Nayakas and but others are warriors, village heads, or farmers.
Velama and Kamma are geographically-derived. Velamas are Velanti vallu (people from Velnadu) and Kammas are Kammanati vallu (people from Kammanadu). Velnadu is current day Guntur/Krishna/Nalgonda/Khammam and Kammanadu is buddhist Kammarastram (Karmarastram) **
Rajus are amalgamation of older kshtriayas and Nayakas.
It is important to note that before Kakatiyas, these castes were fluid and only at 11th century we see castes (right word is Kulam as usage of caste word is confusing ) distinguishing themselves. e.g, Nagamma and Brahma naidu were relatives. Nagamma was identified either as Kamma or Reddy where as Brahman Naidu was clearly identified as Padmanayaka (Velama). Vema Reddy (who started Reddy kingdom in Addanki) and Musunuri Proloya (ruled Kakatiya for 50 years) were relatives. But Vema Reddy was Kapu Reddy where are Musunuri was Kamma. Same Musunuri had relations with other Nayakas who were identified as Kapu Naidus. Even today common family names and Gotras are found in these castes.
* Kapu means protector of farm land. Kapu Reddy, Kapu Naidu, Kamma, Velama are all Kapus/farmer castes
** Looking at diffusion of caste population. Original Kapus were along the Godavari delta. Original Kamma and Velmas were along Krishna/Godavari delta. Original Reddys were diffused from west. Post Kakatiya migration is another story. May be putting in a map makes sense.
