The Dutch were by the nature of their country obliged to seek their means of subsistence upon the sea and in far-off regions. Their famous son, Hugo Grotius, had been the first to proclaim the freedom of the seas as an indispensable condition to the growth and progress of the world's civilization. Since Lisbon had closed her ports to the Netherlands and Spain was imposing a series of unreasonable restrictions upon the navigators of other countries, the Dutch had for some time past been determined to discover a passage by which their ships could penetrate the seas of Asia. Dutch mariners who had been in the employ of the Spaniards and Portuguese and had shared in their voyages of discovery, had brought home tales of the strange lands and stranger peoples, which stirred the imagination of the ambitious and capable nation. The unknown continents and islands stimulated the scholars' desire for investigation and research. Exaggerated reports about the mineral wealth and other treasures of the New World had roused the merchants' spirit of enterprise and acquisition. As visions of the riches that awaited development in those foreign climes, and of territories they might once call their own, rose before the minds of these merchant princes and lords of the sea, the thirst of conquest quickened in this sturdy seafaring people. Step by step the Dutch followed the discoveries and explorations of the Spaniards, and recorded and described them minutely. From the middle of the sixteenth century on the publishing houses of Amsterdam, Leyden and other centers of the printing trade of the country sent out books dealing with the new continent conquered by their enemy, and especially the West Indies. Stirred by this reading, the spirit of the people rose and demanded a share in the lands and the wealth which their mariners had helped to discover. There was an abundance of unemployed labor and capital in the country. Hence the government, knowing only too well that the future of the Dutch people lay on the seas, encouraged this spirit and deliberated upon numerous plans of exploration and colonization. The first step towards a realization of these plans was taken when a charter was granted to the Dutch East India Company, which gave that organization the exclusive right to commerce beyond the Cape of Good Hope on the one side and the Straits of Magellan on the other side. As it recalled similarly privileged institutions in feudal times, when the rights of the classes engaged in trade and industry had to be protected against violation by noble lords, more properly called robber barons, the ideal this company represented appealed to the people. Statesmen of other countries realized its advantages and the Dutch East India Company became the model for the great trade corporations which eventually sprang up in France and England.
