Dear Sitush, I understand your point. If you see this WP Only a few are cited from inscriptions, most of them are well supported by Book citations ( I mean I have given book citations as secondary, I have provided more than 2-3 citations as backup). Please remember that those inscriptions are genuine and they are not manipulated or tricky.
Once can easily corelate the inscription to the actual Rajus WP content.
For E.g The inscription A.R No. 283 of 1924 (krishna dist)says "States that a certain Brahmin Chavali Bhaskara  consecrated the image of Chagi-Ganapesvara and that king Chagi Manma endowed the temple with land.  Describes the Chagi family as of Kshatriya caste (bahujakula) and gives the donor’s genealogy."  > from this inscription We derive Chagi family as belonging to Kshatriya caste - There is only Chagi royal family in entire telugu society, i.e Chagis of Kshatriya Raju's who ruled Krishna dist, later they ruled Peddapuram kingdom also. There are several inscriptions/books/evidences about Rajus/Rajulu as they have been in ruling since 5th century right from Eastern Chalukyas, after medieval period certainly ther kingdoms started diminishing except one or two.
 one can see my contribution to this Rajus WP since three years, I have removed content which was puffery and added content which I was sure about and genuine with backing evidence. I can surely say this Rajus WP just reflects 40-50% of their glorious history. Whatever content I written/write I am sure Majoritarian Andhra historians will agree with me. I agree with you on the point that most of Indian caste make puffery out of nothing, For this I would suggest to Wiki Founders to induldge the Genuine Historians of respective region like Andhra Historical Research Society to be involved and review the caste/community specific WP. I would be one of the happiest persons if it was so. Also please go through this talk page, as most of the answers and relations are explained by Mr. APHistory and myself.
