Final answer:
The triangular trade route was developed during the late 16th century to facilitate efficient exchange of goods between Europe, Africa, and the Americas. It involved three stages: taking manufactured goods from Europe to Africa, shipping African slaves to the Americas, and bringing back crops from the plantations in the Americas to Europe.
Step-by-step explanation:
The triangular trade route was first developed during the late 16th century because it allowed for the efficient exchange of goods between Europe, Africa, and the Americas. This trade route involved three stages. First, manufactured goods were taken from Europe to Africa in exchange for African slaves. Then, the slaves were shipped to the Americas, known as the Middle Passage. Finally, the yield of crops from the slave-labor plantations in the Americas was brought back to Europe.
