Yarlagadda Sivarama Prasad

He was the last hereditary zamindar of the Challapalli Samasthanam (estate) which compromises the modern day region of Diviseema / Avanigadda Assembly constituency .

The Challapalli Samasthanam was one of the largest in the Madras State and consisted of towns in Diviseema and other coastal parts of Krishna District surrounding Machilipatnam.

[7] Sivarama Prasad was crowned on December 26, 1929, an event attended by many Telugu and Sanskrit scholars who advised the new zamindar on how to manage the estate's affairs.

The peasantry in the Challapalli Samasthanam occupied thousands of acres of land owned by Sivarama Prasad, but the Congress-backed police aided the zamindar in putting down the rebellion.

[10][11] In the financial and industrial sector, Sivarama Prasad financed Bhogaraju Pattabhi Sitaramayya's Andhra Bank.
