When did the Transatlantic slave trade notably end?

The Transatlantic slave trade is typically recognized as having ended in the early 19th century, specifically around the 1830s. This timeline corresponds with significant legislative movements in various countries. In the British Empire, for example, the Slavery Abolition Act was passed in 1833, which abolished slavery in most of its territories but did not take effect until 1834. Similarly, the United States had already banned the importation of slaves in 1808, but the trade persisted in various forms until the 1830s.

At this time, public opinion was increasingly turning against the practice of slavery and the slave trade, leading to broader abolitionist movements across Europe and the Americas. Therefore, the early 1830s is often highlighted as a pivotal moment when the practices began to decline in intensity and volume, effectively signaling the end of the Transatlantic slave trade. Other choices do not align with this significant historical endpoint, as events or legislations related to slave trading continued or occurred later.
