  Revolution dynamics is studied through a minimal Ising model with three main
influences (fields): personal conservatism (power-law distributed),
inter-personal and group pressure, and a global field incorporating
peer-to-peer and mass communications, which is generated bottom-up from the
revolutionary faction. A rich phase diagram appears separating possible
terminal stages of the revolution, characterizing failure phases by the
features of the individuals who had joined the revolution. An exhaustive
solution of the model is produced, allowing predictions to be made on the
revolution's outcome.
