 In comparison to First and Second Anglo-Dutch War, political reasons were more important as causes for this war than economic ones.In 1667, Charles II of England had been humiliated by the Dutch Raid on the Medway, and in 1668, Louis XIV of France had been offended by the Dutch preventing his conquest of the Spanish Netherlands through the Triple Alliance.In 1670, the two kings concluded the Secret Treaty of Dover, intending to destroy the Dutch Republic.
