The Burmese King Bayinnong moved his troops to attack Ayutthaya, and he conquered it. So, he asked for King Naresuan as his adopted child while Naresuan was 9 years old. When Naresuan was 16, King Mahathammaracha wanted Naresuan to come back to be a viceroy of Phitsanulok and gave Princess Suphan Kanla Ya instead as the captive from Phitsanulok.
