The Dutch Empire or the Dutch colonial empire () comprised the overseas territories and trading posts controlled and administered by Dutch chartered companies—mainly the Dutch East India Company and the Dutch West India Company—and subsequently by the Dutch Republic (1581–1795), and by the modern Kingdom of the Netherlands after 1815. It was initially a trade-based system which derived most of its influence from merchant enterprise and from Dutch control of international maritime shipping routes through strategically placed outposts, rather than from expansive territorial ventures. The Dutch were among the earliest empire-builders of Europe, following Spain and Portugal and one of the wealthiest nations of that time. With a few notable exceptions, the majority of the Dutch colonial empire's overseas holdings consisted of coastal forts, factories, and port settlements with varying degrees of incorporation of their hinterlands and surrounding regions. Dutch chartered companies often dictated that their possessions be kept as confined as possible in order to avoid unnecessary expense, and while some such as the Dutch Cape Colony and Dutch East Indies expanded anyway (due to the pressure of independent-minded Dutch colonists), others remained undeveloped, isolated trading centres dependent on an indigenous host-nation. This reflected the primary purpose of the Dutch colonial empire: commercial exchange as opposed to sovereignty over homogeneous landmasses. The imperial ambitions of the Dutch were bolstered by the strength of their existing shipping industry, as well as the key role they played in the expansion of maritime trade between Europe and the Orient. Because small European trading-companies often lacked the capital or the manpower for large-scale operations, the States General chartered larger organisations—the Dutch West India Company and the Dutch East India Company—in the early seventeenth century. These were considered the largest and most extensive maritime trading companies at the time, and once held a virtual monopoly on strategic European shipping-routes westward through the Southern Hemisphere around South America through the Strait of Magellan, and eastward around Africa, past the Cape of Good Hope. The companies' domination of global commerce contributed greatly to a commercial revolution and a cultural flowering in the Netherlands of the 17th century, known as the Dutch Golden Age. In their search for new trade passages between Asia and Europe, Dutch navigators explored and charted distant regions such as Australia, New Zealand, Tasmania, and parts of the eastern coast of North America. During the period of proto-industrialization, the empire received 50% of
