1. Abolition Movements: The abolitionist movements in Europe and North America gained momentum in the late 18th century. Countries such as the United Kingdom and France passed laws abolishing the slave trade, making the importation of African slaves increasingly illegal and socially unacceptable.
2. Uprisings and Independence Movements: Several slave uprisings and revolutions occurred in the Caribbean and South America during this period. These movements, including the Haitian Revolution, contributed to the decline of slavery and, consequently, the triangular trade.
3. Economic Changes: The industrial revolution shifted economies towards manufacturing and reduced the reliance on agricultural production based on slave labor.
4. Diplomatic Pressure and Changing Attitudes: Diplomatic pressure from abolitionist nations, such as Britain, and the changing social attitudes toward slavery influenced other countries to reconsider their involvement in the transatlantic slave trade.
While the triangular trade gradually declined and was largely abolished by the mid-19th century, the remnants of slavery and its global impact continued to shape societies for years to come.
