During the Age of Exploration, beginning at the end of the 15th century, most markedly by Columbus´ arrival in America, European powers saw the opportunity to take advantage of unknown cultures around the world that were militarily inferior and so they could be overtaken and subdued, often enslaving the peoples of these cultures for European gain, as well as being able to benefit from the exploitation of the natural resources that these unknown lands procured the Europeans and the new markets that they opened up.
