The watery ally: military inundations in Dutch history

For centuries, the Dutch have fought against their arch-enemy: water. But, during the Dutch War of Independence in the 16th and 17th centuries, the Dutch found an ally in their arch enemy. Their struggle against Spain seemed almost hopeless because the rebels were facing the best trained, supplied and funded European army of that era. As the underdog, they turned to water and used it as a weapon against the Spanish by planning and carrying out a number military inundations, intentionally flooding enormous swaths of land to stop or even defeat the enemy.

However, it is possible that during the Dutch Wars of Independence the province of Holland could have been permanently flooded and lost to the North Sea. The Spanish, hurt by the military inundations, hatched a secret plan that aimed at defeating the Dutch by turning their watery ally against them. Luckily, this plan was never carried out. While Holland survived, the Dutch constructed a line of fortifications and waterworks to facilitate military inundations, which became known as the Dutch Water Line. This militarization of the Dutch landscape had profound long term political, social and environmental consequences for the province and the region.

Episode 77 of the Exploring Environmental History podcast explores these social, political and environmental issues with Robert Tiegs, Adjunct Professor at Sheridan College in Ontario, Canada.
