European and American voyages of scientific exploration

The era of European and American voyages of scientific exploration followed the Age of Discovery and were inspired by a new confidence in science and reason that arose in the Age of Enlightenment. Maritime expeditions in the Age of Discovery were a means of expanding colonial empires, establishing new trade routes and extending diplomatic and trade relations to new territories, but with the Enlightenment scientific curiosity became a new motive for exploration to add to the commercial and political ambitions of the past. See also List of Arctic expeditions and List of Antarctic expeditions.

From the early 15th century to the early 17th century the Age of Discovery had, through Spanish and Portuguese seafarers, opened up southern Africa, the Americas (New World), Asia and Oceania to European eyes: Bartholomew Dias had sailed around the Cape of southern Africa in search of a trade route to India; Christopher Columbus, on four journeys across the Atlantic, had prepared the way for European colonisation of the New World; Ferdinand Magellan had commanded the first expedition to sail across the Atlantic and Pacific oceans to complete the first circumnavigation of the Earth. Over this period colonial power shifted from the Portuguese and Spanish to the Dutch and then the British and French. The new era of scientific exploration began in the late 17th century as scientists, and in particular natural historians, established scientific societies that published their researches in specialist journals. The British Royal Society was founded in 1660 and encouraged the scientific rigour of empiricism with its principles of careful observation and deduction. Activities of early members of the Royal Society served as models for later maritime exploration. Hans Sloane (1650–1753) was elected a member in 1685 and travelled to Jamaica from 1687 to 1689 as physician to the Duke of Albemarle (1653–1688) who had been appointed Governor of Jamaica. In Jamaica Sloane collected numerous specimens which were carefully described and illustrated in a published account of his stay. Sloane bequeathed his vast collection of natural history 'curiosities' and library of over 50,000 bound volumes to the nation, prompting the establishment in 1753 of the British Museum. His travels also made him an extremely wealthy man as he patented a recipe that combined milk with the fruit of Theobroma cacao (cocoa) he saw growing in Jamaica, to produce milk chocolate. Books of distinguished social figures like the intellectual commentator Jean Jacques Rousseau, Director of the Paris Museum of Natural History Comte de Buffon, and scientist-travellers like Joseph Banks, and Charles Darwin, along with the romantic and often fanciful travelogues of intrepid explorers, increased the desire of European governments and the general public for accurate information about the newly discovered distant lands.
