what was the second middle passage

The Second Middle Passage was the forced internal movement of enslaved people within the United States, especially from the Upper South to the Deep South, after the international slave trade ended in 1808. It was driven by the expansion of cotton plantations and the domestic slave trade, and it tore apart many families.

What it means

The term compares this internal slave trade to the original Middle Passage across the Atlantic. Instead of crossing oceans, enslaved people were sold and transported over land, often “down the river” to places like Louisiana, Mississippi, and Alabama.

Why it happened

  • Cotton cultivation expanded rapidly in the early 1800s.
  • Enslavers in the Upper South sold people to meet labor demand in the Deep South.
  • This became one of the largest forced migrations in U.S. history.

Human impact

Historians estimate about one million enslaved people were moved this way between roughly 1808 and 1865. Many were separated from spouses, children, and parents, causing lasting trauma.

In one sentence

It was the domestic slave trade that relocated enslaved African Americans within the U.S. to support cotton slavery, especially in the decades before the Civil War.
