nanda bayin

nanda bayin -lrb- , ; 9 november 1535 -- -rrb- , was king of toungoo dynasty of burma -lrb- myanmar -rrb- from 1581 to 1599 .
he presided over the collapse of toungoo empire , the largest empire in the history of southeast asia .
the eldest son of king bayinnaung was one of the principal commanders in his father 's military campaigns that expanded and defended the empire .
as king , nanda faced the impossible task of keeping his father 's `` improbable domain '' together .
he never gained the full support of his father 's chosen vassal rulers , who governed what used to be sovereign kingdoms just a few decades earlier .
within the first three years of his reign , both upper burma and siam revolted .
though he could never raise more than a third of his father 's troop levels , nanda could not come to terms with a smaller empire .
between 1584 and 1593 , he launched five disastrous invasions of siam , which increasingly weakened his hold everywhere else .
from 1593 onward , it was he who was on the defensive , unable to stop a siamese invasion that seized the entire tenasserim coast in 1594 -- 95 , or prevent the rest of the vassals from breaking away in 1597 .
in 1599 , nanda surrendered to the joint forces of toungoo and arakan , and was taken prisoner to toungoo .
a year later , he was assassinated by natshinnaung .
nanda was an energetic king , who probably would have made an `` above average '' burmese monarch .
but he made the mistake of trying to hold on to an `` absurdly overextended '' empire built mainly on patron-client relationships .
the king 's monumental failures taught his 17th century successors not to overextend their realm and to implement a more centralized administrative system .
the restored toungoo administrative reforms , which with konbaung modifications , would last to the end of burmese monarchy in 1885 , had their origins in the failures of nanda bayin .
