About Ly Cao Tong

Lý Cao Tông, born Lý Long Trát, courtesy name Long Cán, was the seventh emperor of the Lý dynasty, ruled Đại Việt for 35 years. He was enthroned at just three year old and was assisted by the loyal and capable officials such as Tô Hiến Thành, Ngô Lý Tín, which ensured the stability during the early years of his reign. However, when growing up and officially governing, Cao Tông proved to be a hedonistic tyrant. His reign was marked by debauchery, nationwide corruption, legal disorder, harsh forced labor and widespread uprising. His reign entered the irreversible crisis which ultimately led to the fall of the Lý dynasty and the establishment of the Trần dynasty fifteen years after his death.
