The Dutch States Army (Dutch: Staatse leger) was the army of the Dutch Republic. It was usually called this, because it was formally the army of the States-General of the Netherlands, the sovereign power of that federal republic. This mercenary army was brought to such a size and state of readiness that it was able to hold its own against the armies of the major European powers of the extended 17th century, Habsburg Spain and the France of Louis XIV, despite the fact that these powers possessed far larger military resources than the Republic. It played a major role in the Eighty Years' War (opposite the Spanish Army of Flanders) and in the wars of the Grand Alliance with France after 1672.
