The Slave Trade in Portugal refers to the transatlantic trade of enslaved Africans, which was a critical aspect of Portuguese colonial expansion from the 15th to the 19th centuries. This trade allowed Portugal to establish significant economic wealth through the exploitation of enslaved labor on plantations and in mines across its colonies, especially in Brazil and Africa. The practice not only had profound social and economic implications but also contributed to the shaping of racial dynamics and the legacy of colonialism in the Atlantic world.
