This work explores the accomplishments of the golden age of macrohistory, the sociologically informed analysis of long-term patterns of political, economic, and social change that has reached new heights of sophistication in the last decades of the twentieth century. It describes the scholarly revolution that has taken place in the Marxian-inspired theory of revolutions, the shift to a state-breakdown model in which revolutions, rather than bubbling up from discontent below, start at the top in the fiscal strains of the state. The author links revolutions to military-centered transformations of the state, and reviews how he used this theory in the early 1980s to predict the breakdown of the Soviet empire.
