European countries were the earliest countries on earth who consumed all their resourses and utilized them for weopens and other useful materials. European conquest of the New World was motivated by European nation-states' need to gain increasingly scarce resources, compounded by rivalry between nations. By the 15th and 16th centuries, European resources were depleting. Each nation-state looked aggressively for new land, and explorers discovering new terrain took possession in the name of the sponsoring nation. Discovery of new land was followed by rapid and aggressive attempts at colonization.

Europe was growing fast in terms of population and commerce. Human needed buildings to live. For trade, ships were the best vehicles at that time.
