The peace would not last long. In 1548, the Burmese invaded Ayutthaya but failed to take the capital; that same year Photisarath was approached by Burma with offers of an alliance. Photisarath neither accepted the alliance, nor did he support Ayutthaya which had unsuccessfully tried to invade Lan Xang only eight years earlier. In 1550 Photisarath returned to Luang Prabang, but was killed in an accident while riding an elephant in front of the fifteen international delegations which were seeking an audience.
