The chronicle and the archives have recorded that in 1586, King Bayinnaung led his army through the Malamao strait in Tak province to invade Ayutthaya. After long continuous battles, Ayutthaya finally lost the war to the Burmese troops from Hongsawadi in 1569 and end their independence. The collapse of the Ayutthaya Kingdom could not be explained some said that the cause might be the Black Death that wipe out the residents. Some blamed the hungry ghosts, some blamed the plague that came with the Portuguese.
