The power of the Cholas declined about the middle of the thirteenth century and the Pandyas, under Maravarman Sundara I, became aggressive. This king invaded Tondamandalam, subjugated all the Chola subordinates in this region and reached as far north as Nellore and performed Virabhiseka there. There are several records of this Pandyan king in the Tirumala temple (1-44-50 and 56).
