New exports & imports to the Americas

  • The Columbian Exchange began with the arrival of Europeans in the Americas

  • It led to the exchange of plants, animals, and diseases between the ‘New World’ and the ‘Old World

  • This early exchange of goods and resources:

    • Reshaped economies on both sides of the Atlantic

    • Set the stage for the development of new trade systems

Transatlantic Trade

  • The Triangle Trade or Transatlantic Trade took place between the 16th and 19th centuries

  • This system of trade exchanged goods, services, and ideas among the Americas, Africa, and Europe

  • This trading structure was also used to transport captured African peoples to the Americas to become part of an enslaved labor force

African Enslaved Labor

  • The Portuguese brought captured Africans to the Caribbean and South America after they decimated the Indigenous population

  • Many Africans were enslaved in South and Central America

    • A smaller number of Africans were enslaved in North America

  • African enslavement expanded to North America 

    • 1619 marks the first recorded instance of Europeans bringing kidnapped Africans over to the Americans

      • The English privateer ship The White Lion brought 20−30 individuals to Port Comfort in Virginia

      • The people were raided for supplies

      • More enslaved Africans arrived in Virginia aboard a second English ship called The Treasurer days later

  • The 18th century was the peak period of transporting captured Africans for use as enslaved labor

  • Other trade items included:

    • Europe to the Americas: Livestock such as horses, pigs, and cattle

    • Europe to Africa: Metal, gunpower, iron, tools, and textiles

    • North America to Europe: Sugar, rice, tobacco, cotton, and molasses

Middle Trade or Middle Passage

  • The route Europeans used to bring captured Africans from western Africa to the Americas became known as the Middle Trade or Middle Passage

  • Between 15-20 percent of the captured Africans did not survive the journey due to:

    • Lack of sanitary conditions that led to disease

    • Infectious diseases such as smallpox and measles

    • Lack of food

    • Accidents

    • Punishment for rebelling against being held captive

Shift from feudalism to capitalism

  • Europeans brought the idea of feudalism with them when they arrived in the ‘New World’

  • This system of hierarchy meant that common people in society lived and worked on land owned by rich nobles

  • The nobles offered military protection to the commoners or peasants who worked the land

  • Feudalism disappeared in the ‘New World’ due to:

    • the introduction of new trade markets

    • new opportunities for wealth

    • the creation of new labor systems

  • The decline of feudalism led to the rise of the middle/merchant class and the development of new industries 

  • As feudalism declined, the system of capitalism was created based on trade, industry, and banking 

  • A currency system replaced barter systems
