 For roughly a millennium a series of Chinese dynasties had controlled northern Vietnam , until the independence of the Ngô dynasty ( 939 – 967 ) . Early Song armies had fought and lost to the Early Lê dynasty ( 980 – 1009 ) of Vietnam at the Battle of Bạch Đằng in 981 . Subsequently the Zhuang rebel Nong Zhigao ( Nùng Trí Cao ) ( 1025 – 1053 ) attempted to establish his own frontier kingdom in 1042 , 1048 , and 1052 , creating a disturbance on Song 's southern border that prompted an invasion against Nong Zhigao / Nùng Trí Cao 's forces in the 1050s . This invasion resulted in the Song conquest of border regions inhabited by Tai peoples and a border confrontation with the Lý dynasty ( 1010 – 1225 ) that lasted from 1075 to 1077 . The Song court 's interest in maximizing the economic benefits of these frontier zones came into conflict with the Lý dynasty , whose goal was to consolidate their peripheral fiefdoms . In the aftermath , an agreement was negotiated by both sides that fixed the borders ; the resulting line of demarcation " would largely remain in place through to the present day " , according to James A. Anderson , Associate Professor in the History Department at the University of North Carolina .

 Vietnam was a tumultuous place during Ba Cụt 's youth , particularly in the Mekong Delta . In 1939 , Huỳnh Phú Sổ founded the Hòa Hảo religious movement , and within a year had gained more than 100 @,@ 000 followers . He drew adherents for two reasons : the prophecies he made about the outbreak of World War II and the conquest of South @-@ East Asia by Japan , which proved to be correct ; and his work as a mystical healer — his patients claimed to have been miraculously cured from all manner of serious illnesses after seeing him , when Western medicine had failed . Sổ 's cult @-@ like appeal greatly alarmed the French colonial authorities . During World War II , Imperial Japan invaded and seized control of Vietnam from France ; its defeat and withdrawal at the end of the war in 1945 left a power vacuum in the country .
