The Anatomy of Revolution is a book by Crane Brinton outlining the "uniformities" of four major political revolutions: the English Revolution of the 1640s, the American, the French, and 1917 Russian Revolution. Brinton notes how the revolutions followed a life-cycle from the Old Order to a moderate regime to a radical regime, to Thermidorian reaction. The book has been called "classic, "famous" and a "watershed in the study of revolution," and has been influential enough to have inspired advice given to US President Jimmy Carter by his National Security Advisor Zbigniew Brzezinski during the Iranian Revolution.
