Candrarāja succeeded his father at Vicitraprakāra at the age of 30, in the year 546 of the
Chula Sakarat Era (1184 CE). Subsequently, after the death of his cousin
Pra Poa Noome Thele Seri in 1204/05, he moved northward to reconstruct
Sukhothai, establishing it as his new political and administrative center. He then ceased the payment of tribute to the suzerain polity of
Indaprasthanagara () following the counsel of his elder son,
Si Inthrathit. This defiance precipitated hostilities between the two realms; however, the Sukhothai forces, commanded by Si Inthrādhit, achieved victory. Thereafter,
Indaprasthanagara refrained from interfering in Sukhothai's internal affairs. It is further recorded that Lavo was under his authority following this episode. Around 1200 CE, Sukhothai’s southern neighbor—a polity in the
Phraek Si Racha region known as
Chen Li Fu (possibly
Indaprasthanagara)—is recorded to have asserted a degree of autonomy by independently dispatching tribute to the Chinese imperial court. This polity has also been speculated to have maintained some form of dynastic connection with Angkor. == Death and succession ==
