The European colonization of the Americas encountered diverse physical and human geography, which influenced the methods and results. Spanish Conquistadors found large native empires in Mexico and Peru and quickly conquered them to build feudal systems similar to those at home. Where valuable mineral deposits were found, colonies were built on that basis. Places suitable to sugar developed a plantation economy. North America, where such resources were not found, was colonized later, mainly by France, England, and the Netherlands. Their colonies were initially based on trade with the natives rather than conquest, and later on lumber rather than minerals. Where farmland was good, an export trade in its products developed.
