Vietnam was in a civil war in the 17th century between the Trinh lords based in Tonkin in north Vietnam at Hanoi and the Nguyen lords in central and south Vietnam.

The Nguyen lords allied with the Portuguese and the Trinh lords allied with the Dutch.

The Dutch captured Vietnamese slaves from fighting the Nguyen lords (calling them Quinamese after Quang Nam aka Quinam).

The Trinh lords in Tonkin, north Vietnam allowed foreign Dutch men and English men to have rampant sexual relations with north Vietnamese women in cities like Hanoi and Haiphong (Doméa).
