About this source
What it is
This is the printed text of a speech delivered by John Quincy Adams before the U.S. Supreme Court on February 24 and March 1, 1841, in the case concerning Cinque and other Africans captured aboard the schooner Amistad. It was printed in New York in 1841 and is held by the Library of Congress.
Why it matters
By 1841 Adams was an elderly former president, yet he took on the defence of the Amistad Africans, arguing from principles of natural rights against slavery. The speech also reviewed an earlier case, that of the ship Antelope, connecting it to the broader struggle over slavery and freedom in American law.
