1. Asia has a lot of people which is beneficial in trading and opening ports. They had items like silk, spices, and gunpowder which were considered rare goods at the time.
2. Africa contained a lot of gold which was very valuable. Because of this, this led European monarchies to colonize African regions with the most gold.
3. Increased international trade greatly improved the standard of living for both Americans and Europeans because international trade increases the economy of a country as well as the economic condition of citizens. The better economic condition is, the purchasing power of people increases which results in the standard of living being improved.
4. American and European imperialism grew for economic, political, military reasons. Military power was important in imperialism. Economic imperialism would help the trade industry. Imperialism in Asia, Africa and Latin America brought modernization and resources but greatly destroyed cultures. Imperialism in America caused slavery-like conditions among the workforce.
Have a great day :)
