Slavery in New England played a significant role in the region's early history. Cities like Boston and Newport were important ports for the transatlantic slave trade, with ships bringing enslaved Africans to be sold throughout the colonies. And while slavery had largely disappeared in New England by the early 19th century, the legacy of this institution had a lasting impact on the region's economic and social development.
