Alfred coined the term Columbian exchange in 1972. The Columbian exchange started to connect the New and Old Worlds with the transmission of ideas, plants, animals, and diseases. Two worlds that had grown apart with very different organisms started to become homogeneous (Crosby, 1972).
The term was coined by historian Alfred Crosby in 1972, although the event took place hundreds of years earlier. The Columbian Exchange is considered to have been of great benefit to the Europeans who sought to spread out and conquer other lands, but it ultimately brought disaster to the Native Americans.
