The Colombian exchange is the circle of trade routes established by Christopher Columbus upon reaching the New World, or the Americas. This exchange created a massive impact on the western world. One of the biggest things it did was to spread new foods and products throughout Europe, like tomatoes, coffee, potatoes, and other items. It increased the power and influence of mercantilism and created new wealth for many in Europe.
Unfortunately, on the negative side, the Columbian Exchange also encouraged slavery and widened its impact. One of the legs of the Columbian Exchange was the transport of slaves from Africa to the Americas, and this accelerated slavery in the new world drastically. In the end, the trade routes established created massive changes that reverberated throughout the western world.
