The major trade network that was established between the Americas, Africa, Asia and Europe was known as the Exchange

: The major trade network you are referring to is known as the Columbian Exchange. This was the widespread transfer of plants, animals, culture, human populations (including slaves), technology, and ideas between the Americas and the Old World (Africa, Asia, and Europe) following Christopher Columbus’s voyage to the Americas in 1492. The exchange had a significant impact on the world, leading to changes in agriculture, cuisine, populations, and even the environment.

Key elements transferred from the Old World to the New World included horses, cattle, sheep, pigs, and wheat, while from the New World to the Old World, key items included maize (corn), potatoes, tomatoes, sweet potatoes, and other crops. Unfortunately, along with these goods, diseases were also transferred, with devastating effects on indigenous American populations, who lacked immunity to Old World diseases such as smallpox and influenza.
