institutions of Western Europe diverged from those in Eastern Europe and then how those of England diverged from those in the rest of Western Europe. This was a consequence of small institutional differences, mostly resulting from institutional drift interacting with critical junctures. It might then be tempting to think that these institutional differences are the tip of a deep historical iceberg where under the waterline we find English and European institutions inexorably drifting away from those elsewhere, based on historical events dating back millennia. The rest, as they say, is history.
Except that it isn’ t, for two reasons. First, moves toward inclusive institutions, as our account of Venice shows, can be reversed. Venice became prosperous. But its political and economic institutions were overthrown, and that prosperity went into reverse. Today Venice is rich only because people who make their income elsewhere choose to spend it there admiring the glory of its past. The fact that inclusive institutions can go into reverse shows that there is no simple cumulative process of institutional improvement.
Second, small institutional differences that play a crucial role during critical junctures are by their nature ephemeral. Because they are small, they can be reversed, then can reemerge and be reversed again. We will see in this chapter that, in contrast with what one would expect from the geography or culture theories, England, where the decisive step toward inclusive institutions would take place in the seventeenth century, was a backwater, not only in the millennia following the Neolithic Revolution in the Middle East but also at the beginning of the Middle Ages, following the fall of the Western Roman Empire. The British Isles were marginal to the Roman Empire, certainly of less importance than continental Western Europe, North Africa, the Balkans, Constantinople, or the Middle East. When the Western Roman Empire collapsed in the fifth century AD, Britain suffered the most complete decline. But the political revolutions that would ultimately bring the Industrial Revolution would take place not in Italy, Turkey, or even western continental Europe, but in the British Isles.
In understanding the path to England’ s Industrial Revolution and the countries that followed it, Rome’ s legacy is nonetheless important for several reasons. First, Rome,
