Trịnh–Nguyễn War
As the site contained several mountain passes, it has historically been a center for conflict between ruling powers and dynastic struggles. The site was the scene of heavy inter-dynastic fighting between the Trịnh–Nguyễn War and the point in which the Nguyen dynasty had escaped following their expulsion from their strongholds in the north. Its primary city of Hội An was destroyed and rebuilt during the Tay Son rebellion.
