The burden of over-population with which Spain, France, and Portugal were troubled, and to relieve the pressure of which was one of the motives of their colonizing efforts, was not felt by Holland; for despite the fact that she sustained a more dense population than any other European State, her citizens were prosperous. They were not stirred, like neighboring peoples, by the impulse of emigration. Preeminently a trading nation, Holland sought commerce rather than extension of empire. Long the chief carrier of Europe before striking into a broader field, she followed in the steps of the Portuguese, and by the opening of the seventeenth century took rank as a colonizing power. Her most fruitful labors were in the East rather than in the West. It was in the attempt to find the northwest passage to India that Hudson discovered the river which bears his name. With the Dutch, though religious reformers, religion was secondary to trade. So long as trade was good, they were patient under insult and outrage. Individually they made but little impress upon the community. Commerce was chiefly conducted through large chartered companies, minutely managed in Holland. Dutch colonies declined because their commercial system was non-progressive and unsound; they appear to have been unable to rise out of the trader state. Yet we must not forget that Holland was of small size and had overbearing, jealous neighbors; her long and heroic struggle with Spain tended greatly to delay her efforts to trade in and colonize the New World. Sidenote: Sweden. The Swedish colony on the Delaware was planned by authority of Gustavus Adolphus on broad, liberal principles; he hoped it would become "the jewel of his kingdom." But while it throve for a time and gave much promise of endurance, the Dutch soon overpowered it. Had the Swedish monarch lived to carry out the design, doubtless he would have proved that Scandinavians could successfully maintain an independent province in the New World. Like the Germans, however, they have in later years been in the main content to colonize as the subjects of foreign governments. 22. English Policy. Sidenote: England.
