Expansion and Division
•As southern
expansion continued, the central
government in Hanoi had increasing
difficulties establishing their authority
in the south.
•By the 16th
century, a rival dynasty (the
Nguyen) emerged to challenge the
northern Trinh dynasty.
•For two
centuries, the war between the Trinh
and Nguyen continued.
•Internal war
weakened the Vietnamese
when it became necessary to
face an external threat from
European imperialism.
