Answer: Map depicting the European exploration of the New World in the 15th and 16th centuries, including the voyages made by Christopher Columbus, John Cabot, Alonso de Ojeda and Amerigo Vespucci, Pedro Álvares Cabral, Ferdinand Magellan and Juan Sebastián del Cano, Giovanni da Verrazzano, Jacques Cartier, Sir Francis Drake, and others. The lines of demarcation represent an early division between the territory of Spain (to the west) and Portugal (to the east).
The motives that spur human beings to examine their environment are many. Strong among them are the satisfaction of curiosity, the pursuit of trade, the spread of religion, and the desire for security and political power. At different times and in different places, different motives are dominant. Sometimes one motive inspires the promoters of discovery, and another motive may inspire the individuals who carry out the search.
For a discussion of the society that engaged in these explorations, and their effects on intra-European affairs, seeEuropean history. The earliest European empires are discussed in ancient Greek civilization and ancient Rome.
The threads of geographical exploration are continuous and, being entwined one with another, are difficult to separate. Three major phases of investigation may nevertheless be distinguished. The first phase is the exploration of the Old World centred on the Mediterranean Sea, the second is the so-called Age of Discovery, during which, in the search for sea routes to Cathay (the name by which China was known to medieval Europe), a New World was found, and the third is the establishment of the political, social, and commercial relationships of the New World to the Old and the elucidation of the major physical features of the continental interiors—in short, the delineation of the modern world.
