The document discusses the globalization and international exchange that occurred between Western countries and other parts of the world from the 15th century onward. It describes how Western countries, led by Portugal and Spain, sought to increase trade routes and colonize new lands through maritime expeditions. This allowed for the spread of Western cultural and political beliefs around the world as well as an imbalance in trade relationships that benefited Western nations. While some indigenous populations resisted participating in the new world economy and trade systems, globalization generally expanded Western influence and power over time through imperialism and colonialism.
