The rebellion was rooted in long-standing grievances over land exploitation and forced trade agreements. Dutch authorities traded cloth for indigenous land, displacing Plains Aboriginal communities. Guo’s uprising targeted Dutch markets in Tainan, shutting down critical economic hubs[1].
To quell dissent, the Dutch constructed Fort Provintia near Sakam, a site offering control over inland trade routes. The fort housed 40–50 soldiers and served as the Dutch administrative heart[3]. After Koxinga’s 1661 invasion, the fort fell to Zheng clan forces and later degraded into an ammunition depot under Qing rule[1][2].
Physical remnants like the Bixi turtle steles – inscribed with Qianlong’s poems commemorating Qing military victories – remain as testimonies to the site’s layered colonial past. These artifacts bridge Dutch-era conflicts with Qing-era consolidation efforts[1].
The fort’s design ultimately reflected its dual role: a military deterrent and a symbol of colonial authority. Its construction marked the Dutch effort to assert dominance after the rebellion, while its subsequent repurposing under Koxinga underscored shifting power dynamics in early Taiwanese history[1][2].
