Holland’s recent successes, especially at sea, against Spain and the Barbary States, had made her very confident in her maritime power. England was then much exhausted, from internal dissension, and Holland was anxious to be considered mistress of the Narrow Seas, a right which England had long claimed, and which the Dutch had always firmly disputed. The Prince of Orange died rather suddenly, leaving his heir yet unborn, and the Democratic party, which comprised the most liberal and enlightened of the Dutch people, seized the opportunity to abolish the office of Stadtholder, and restore a pure Republic. After their success in this it was thought and hoped that at least a close alliance, offensive and defensive, might be formed between the two Republican States. An ambassador was sent from England to Holland for that purpose, but the negotiation lagged. The “High Mightinesses” who now ruled Holland offered a counter-proposition. Delays followed, and St. John, the English envoy, whose time was limited to a certain fixed date, had his pride hurt by the delay. The Dutch, on their side, thought it arrogant and menacing in the English Parliament to have set a time for their action and its agent’s return. The exiled court was then at the Hague, and the exiled cavaliers frequently made St. John feel their presence. Then, again, Holland may have wished to see the result of the invasion of Scotland, and, after long delays, St. John left Holland, more inclined for war than peace. The Dutch statesmen saw their mistake after the battle of Worcester had firmly established the English commonwealth, and now endeavored to renew negotiations. But new troubles prevented an understanding. Dutch privateers had continued to injure English commerce; while still more insuperable difficulties arose from the passage by the English Parliament of the Navigation Act. At that time, in addition to being great traders, the Dutch were great fishermen. Rotterdam and Amsterdam were the exchanges of Europe, and immense fortunes were made by the ship owners of these ports. Under the Stuarts England had neglected the merchant marine, and afforded a fine field to the Dutch traders, but the Navigation Act, in declaring that no goods the produce of Asia, Africa or America, should be imported into England, except in vessels either belonging to that commonwealth or to the countries from which the goods were imported, put a period, so far as the British Islands, their colonies and dependencies were concerned, to a very lucrative branch of Dutch enterprise.
