"Eighty Years" refers to a significant period in history, often associated with the Eighty Years' War, which took place from 1568 to 1648. This conflict was primarily between the Spanish Empire and the Dutch Republic, as the Dutch sought independence from Spanish rule. The war was marked by various battles, political maneuvers, and the eventual recognition of Dutch sovereignty. The conclusion of the war was formalized in the Treaty of Westphalia, which not only recognized the independence of the Netherlands but also reshaped the political landscape of Europe. This period is notable for its impact on trade, culture, and the rise of the Dutch Golden Age.
