1568 – 1648
A tax revolt in the richest provinces of Europe became an eighty-year war against the most powerful empire on earth — and won. The Dutch lost nearly every open battle, held their cities behind water and earthworks until Spain went bankrupt paying for the sieges, and invented modern warfare in the process: drill, volley fire, and the military academy. What emerged was a republic with no king, the world's first stock exchange, and a global maritime empire that had begun as seven waterlogged provinces refusing to pay.
