The main reason for the exploration of the New World by European powers was the pursuit of wealth, particularly in the form of gold and silver, as well as the desire for new trade routes. Additionally, European nations sought to expand their empires, spread Christianity, and gain strategic advantages over their rivals. The competition among Spain, France, England, and other nations led to extensive exploration and colonization efforts beginning in the late 15th century. The discoveries by explorers such as Christopher Columbus opened the door to vast territories and resources in the Americas.
