hi sps sir,

this weeks doubt (....)

bit confused on the vengi wars - can you help to clear.

RRC - daugther Kundavai marries vimaladityan. their offspring
rajaraja narendra - after much difficulty marries daughter of RJC -
ammanga devi ( 1022)...

now who is Vijayaditya VII, who is supported by western chalukyan
king jaysimhan?? RJC comes to support narendra , wins and is crowned
king

again in 1031 again narendra is diven out and vijayaditya is
crowned - 1035 RJC comes back - drives out vijayaditya and crowns
narendra...

was vijayadityan the offspring of vimaladityan via his marriage to
western chalukyan princess - if so who was the rightful heir.
