was much larger than the prefarming one. In general, villages grew by between two and six times when the transition took place. Moreover, many of the consequences that people have traditionally argued as having flowed from this transition undoubtedly happened. There was greater occupational specialization and more rapid technological progress, and probably the development of more complex and possibly less egalitarian political institutions. But whether this happened in a particular place was not determined by the availability of plant and animal species. Instead, it was a consequence of the society’s having experienced the types of institutional, social, and political innovations that would have allowed sedentary life and then farming to emerge.
Though the Long Summer and the presence of crop and animal species allowed this to happen, it did not determine where or when exactly, after the climate had warmed up, it would happen. Rather, this was determined by the interaction of a critical juncture, the Long Summer, with small but important institutional differences that mattered. As the climate warmed up, some societies, such as the Natufians, developed elements of centralized institutions and hierarchy, though these were on a very small scale relative to those of modern nation-states. Like the Bushong under Shyaam, societies reorganized to take advantage of the greater opportunities created by the glut of wild plants and animals, and it was no doubt the political elites who were the main beneficiaries of these new opportunities and of the political centralization process. Other places that had only slightly different institutions did not permit their political elites to take similar advantage of this juncture and lagged behind the process of political centralization and the creation of settled, agricultural, and more complex societies. This paved the way to a subsequent divergence of exactly the type we have seen before. Once these differences emerged, they spread to some places but not to others. For example, farming spread into Europe from the Middle East starting around 6500 BC, mostly as a consequence of the migration of farmers. In Europe, institutions drifted away from parts of the world, such as Africa, where initial institutions had been different and where the innovations set in motion by the Long Summer in the Middle East happened only much later, and even then in a different form.
THE INSTITUTIONAL INNOVATIONS of the Natufians, though they did most likely underpin the Neolithic Revolution, did not leave a simple legacy in world history and did not lead inexorably to the long-run prosperity of their homelands in modern Israel, Palestine, and Syria. Syria and Palestine are relatively poor parts of the modern world, and the prosperity of Israel was largely imported by the settlement of Jewish people after the Second World War and their high levels of education and easy access to advanced technologies. The early growth of the Natufians did not become sustained for the same reason that Soviet growth fizzled out. Though highly significant, even revolutionary for its time, this was growth under extractive institutions. For the Natufian society it was also likely that this type of growth created deep conflicts over who would control institutions and the extraction they enabled. For every elite benefiting from extraction there is a non-elite who would love to replace him. Sometimes infighting simply replaces one elite with another. Sometimes it destroys the whole extractive society, unleashing a process of state and societal collapse, as the spectacular civilization that Maya city-states built more than one thousand years ago experienced.
THE UNSTABLE EXTRACTION
Farming emerged independently in several places around the world. In what is now modern Mexico, societies formed that established states and settlements, and transitioned to agriculture. As with the Natufians in the Middle East, they also achieved some degree of economic growth. The Maya city-states in the area of southern Mexico, Belize, Guatemala, and Western Honduras in fact built a fairly sophisticated civilization under their own brand of extractive institutions. The Maya experience illustrates not only the possibility of growth under extractive institutions but also another fundamental limit to this type of growth: the political instability that emerges and ultimately leads to collapse of both society and state as different groups and people fight to become the extractors.
Maya cities first began to develop around 500 BC. These early cities eventually failed, sometime in the first century AD. A new political model then emerged, creating the foundation for the Classic Era, between AD 250 and 900. This period marked the full flowering of Maya culture and civilization. But this more sophisticated civilization would also collapse
