Final answer:
The Portuguese established control over trade in the Indian Ocean to tap into the spice trade and redirect it to Europe. Venice and other Italian states lost power and wealth due to the new Portuguese trade routes. Future international trade would be different as Western European countries developed new sea trade routes, leading to increased trade, exploration, colonization, and the establishment of global trade networks.
Step-by-step explanation:
According to Boorstin, the Portuguese established control over trade in the Indian Ocean in order to tap into the lucrative spice trade and divert it to a European sea trade. By establishing control over the trade routes, Portuguese ships were able to bring valuable spices, drugs, gems, and silks directly to Atlantic-facing Europe, bypassing the traditional routes through the Persian Gulf, the Red Sea, and the Levant.
The trading powers that lost power and wealth because of the new Portuguese trade routes were Venice and other Italian states that had monopolized trade with the Muslim world through the overland spice trade routes. The flow of Asiatic treasure, which included spices, silks, and other goods, shifted from the Persian Gulf, the Red Sea, and the Levant to Portuguese ships traveling around the Cape of Good Hope to Europe.
Future international trade would be different because Western European countries, like Portugal, Spain, and other European powers, developed new sea trade routes to Asia. These new trade routes opened up opportunities for increased trade and contact with Asian cultures, leading to the exploration and colonization of new territories, the spread of European influence, and the establishment of global trade networks.
