What role did they play in the struggle between the spanish and the dutch?

The Dutch and Spanish conflict primarily revolved around the Eighty Years' War (1568-1648), where the Dutch sought independence from Spanish rule. The Dutch Republic, driven by a desire for religious freedom and economic autonomy, engaged in naval battles and formed alliances, notably with England and France. This struggle was marked by significant naval warfare, including the establishment of the Dutch East India Company, which challenged Spanish maritime dominance. Ultimately, the conflict culminated in the recognition of Dutch independence through the Treaty of Westphalia in 1648.
