She also wrote and starred in a four-part documentary regarding the role of women in society, entitled The Ascent of Woman.
Foreman was born in London. Her parents were Evelyn (Smith) and the screenwriter and film producer Carl Foreman (1914–1984). Her father moved to England to work after being blacklisted by the Hollywood movie studios during the McCarthyism of the 1950s. Her brother, Jonathan Foreman, is an international correspondent and film critic. She has five children and is married to Jonathan Barton.
Amanda Foreman was educated at Hanford School, a girls' junior independent school in southwest England, followed by various girls' boarding schools. She attended Sarah Lawrence College in Yonkers, New York, then Columbia University, before returning to England in 1991. She was awarded a 1993 Henrietta Jex-Blake Senior Scholarship at Lady Margaret Hall, Oxford. At Oxford, Foreman completed an MPhil thesis Politics or Providence?: Why the Houses of Parliament voted to abolish the slave trade in 1807 (1993) and a DPhil with her thesis The political life of Georgiana, Duchess of Devonshire, 1757–1806 (1998) which was then turned into her first biography.
After completing her DPhil, Foreman remained at Oxford as a researcher, and in 1998 she published her first book, Georgiana, Duchess of Devonshire, based on her doctoral thesis. Published by HarperCollins in the UK and Random House in the US, the book was an international best-seller and reached number one in the UK as a hardback, paperback, and reissue nine years later. It was shortlisted for the 1998 Guardian First Book Prize, and won the 1998 Whitbread Prize for Best Biography. The book has been the subject of a television documentary, a radio play, starring Judi Dench, and a film, The Duchess, starring Ralph Fiennes and Keira Knightley.
