Suriyothai was queen during the early part of the reign of King Maha Chakkraphat (2091 to 2106 Buddhist Era, with another reign from 2111 to 2112 B.E.). In 1548 AD, barely six months into King Maha Chakkraphat's reign, the King of Burma invaded Siam with the intent of sacking the main capital, Ayutthaya.
