Against which country did the Dutch Republic fight the Eighty Years' War?
Explanation
The Dutch Republic fought the Eighty Years' War against Spain. The conflict arose due to religious tensions and power struggles between the Protestant Dutch provinces and the Catholic Spanish Habsburgs, who ruled over the Seventeen Provinces (including present-day Netherlands). The Dutch Republic sought to gain independence and establish religious freedom, which clashed with Spain's goal of maintaining Catholic dominance. This prolonged war, spanning from 1568 to 1648, eventually led to the recognition of an independent Dutch state and marked an important turning point in European history.
