The Columbian Exchange, The Americas, and Africa

The exchange of trade and Colombia has had a tremendous impact on the world between the AD 1450 and the year 1750. The Colombian Stock Exchange helps link the United States, Africa and Europe, and a huge international trade network helps shape the world. In these trading networks, spice, silver, slavery, sugar trading are particularly important that affect the world. Silver trading has become an important part of the world economy and has made Europe involve more East Asian trade. Silver is the center of world trade and is more important than spice trade in building a global trade network. Most of the circulating silver is from the United States, especially Potosí of Bolivia. Because Potosi is closest to the world's largest silver mine, it is the largest city in the Americas. Early modern times, Spain and the United States produced about 85% of the world's silver. Spanish silver excavated from this mine was brought into Europe for the purchase of African slaves and Asian goods, especially spices.

Before 1492, there was little connection between the New World and Eurasia and Africa. When Columbus comes in contact with the Americas, it will begin to exchange crops, slaves, and diseases known as Colombian exchanges. Agriculture is the way to use least developed countries. Europe uses American raw materials to enrich itself. In the past agriculture was mainly used as a food source of the population. After that, agriculture was also used for the production of products such as tobacco and sugarcane (which means that agriculture has become more important in world trade).
